A term meaning acceptance, forbearance, or patience. As the third of the six perfections, patience is classified into three kinds: the capacity to tolerate abuse from sentient beings, to tolerate the hardships of the path to buddhahood, and to tolerate the profound nature of reality. As a term referring to a bodhisattva’s realization, dharmakṣānti (chos la bzod pa) can refer to the ways one becomes “receptive” to the nature of Dharma, and it can be an abbreviation of anutpattikadharmakṣānti, “forbearance for the unborn nature, or nonproduction, of dharmas.”

Lit. “Not Disturbed” or “Immovable One.” The buddha in the eastern realm of Abhirati. A well-known buddha in Mahāyāna, regarded in the higher tantras as the head of one of the five buddha families, the vajra family in the east.

A major śrāvaka disciple and personal attendant of the Buddha Śākyamuni during the last twenty-five years of his life. He was a cousin of the Buddha (according to the Mahāvastu, he was a son of Śuklodana, one of the brothers of King Śuddhodana, which means he was a brother of Devadatta; other sources say he was a son of Amṛtodana, another brother of King Śuddhodana, which means he would have been a brother of Aniruddha).

Ānanda, having always been in the Buddha’s presence, is said to have memorized all the teachings he heard and is celebrated for having recited all the Buddha’s teachings by memory at the first council of the Buddhist saṅgha, thus preserving the teachings after the Buddha’s parinirvāṇa. The phrase “Thus did I hear at one time,” found at the beginning of the sūtras, usually stands for his recitation of the teachings. He became a patriarch after the passing of Mahākāśyapa.

The king of Magadha and a great patron of the Buddha. His birth coincided with the Buddha’s, and his father, King Mahāpadma, named him “Essence of Gold” after mistakenly attributing the brilliant light that marked the Buddha’s birth to the birth of his son by Queen Bimbī (“Goldie”). Accounts of Bimbisāra’s youth and life can be found in The Chapter on Going Forth (Toh 1-1, Pravrajyāvastu).

King Śreṇya Bimbisāra first met with the Buddha early on, when the latter was the wandering mendicant known as Gautama. Impressed by his conduct, Bimbisāra offered to take Gautama into his court, but Gautama refused, and Bimbisāra wished him success in his quest for awakening and asked him to visit his palace after he had achieved his goal. One account of this episode can be found in the sixteenth chapter of The Play in Full (Toh 95, Lalitavistara). There are other accounts where the two meet earlier on in childhood; several episodes can be found, for example, in The Hundred Deeds (Toh 340, Karmaśataka). Later, after the Buddha’s awakening, Bimbisāra became one of his most famous patrons and donated to the saṅgha the Bamboo Grove, Veṇuvana, at the outskirts of the capital of Magadha, Rājagṛha, where he built residences for the monks. Bimbisāra was imprisoned and killed by his own son, the prince Ajātaśatru, who, influenced by Devadatta, sought to usurp his father’s throne.

A high-ranking deity presiding over a divine world; he is also considered to be the lord of the Sahā world (our universe). Though not considered a creator god in Buddhism, Brahmā occupies an important place as one of two gods (the other being Indra/Śakra) said to have first exhorted the Buddha Śākyamuni to teach the Dharma. The particular heavens found in the form realm over which Brahmā rules are often some of the most sought-after realms of higher rebirth in Buddhist literature. Since there are many universes or world systems, there are also multiple Brahmās presiding over them. His most frequent epithets are “Lord of the Sahā World” (sahāṃpati) and Great Brahmā (mahābrahman).

This refers to what occurs at the end of an arhat’s or a buddha’s life. When nirvāṇa is attained at awakening, whether as an arhat or buddha, all suffering, afflicted mental states (kleśa), and causal processes (karman) that lead to rebirth and suffering in cyclic existence have ceased, but due to previously accumulated karma, the aggregates of that life remain and must still exhaust themselves. It is only at the end of life that these cease, and since no new aggregates arise, the arhat or buddha is said to attain parinirvāṇa, meaning “complete” or “final” nirvāṇa. This is synonymous with the attainment of nirvāṇa without remainder (anupadhiśeṣanirvāṇa).

According to the Mahāyāna view of a single vehicle (ekayāna), the arhat’s parinirvāṇa at death, despite being so called, is not final. The arhat must still enter the bodhisattva path and reach buddhahood (see Unraveling the Intent, Toh 106, 7.14.) On the other hand, the parinirvāṇa of a buddha, ultimately speaking, should be understood as a display manifested for the benefit of beings; see The Teaching on the Extraordinary Transformation That Is the Miracle of Attaining the Buddha’s Powers (Toh 186), 1.32.

The term parinirvāṇa is also associated specifically with the passing away of the Buddha Śākyamuni, in Kuśinagara, in northern India.

A state of deep concentration in which the mind is absorbed in its object to such a degree that conceptual thought is suspended. It is sometimes interpreted as settling (āhita) the mind in equanimity (sama).

A state of involuntary existence conditioned by afflicted mental states and the imprint of past actions, characterized by suffering in a cycle of life, death, and rebirth. On its reversal, the contrasting state of nirvāṇa is attained, free from suffering and the processes of rebirth.

The deities ruled over by Māra. The term can also refer to the devas in his paradise, which is sometimes identified with Paranirmitavaśavartin, the highest paradise in the realm of desire. This is distinct from the four personifications of obstacles to awakening, also known as the four māras (devaputramāra, mṛtyumāra, skandhamāra, and kleśamāra).

Speaker or reciter of scriptures. In early Buddhism a section of the saṅgha would consist of bhāṇakas, who, particularly before the teachings were written down and were only transmitted orally, were a key factor in the preservation of the teachings. Various groups of dharmabhāṇakas specialized in memorizing and reciting a certain set of sūtras or vinaya.

Eighteen special features of a buddha’s behavior, realization, activity, and wisdom that are not shared by other beings. They are generally listed as: (1) he never makes a mistake, (2) he is never boisterous, (3) he never forgets, (4) his concentration never falters, (5) he has no notion of distinctness, (6) his equanimity is not due to lack of consideration, (7) his motivation never falters, (8) his endeavor never fails, (9) his mindfulness never falters, (10) he never abandons his concentration, (11) his insight (prajñā) never decreases, (12) his liberation never fails, (13) all his physical actions are preceded and followed by wisdom (jñāna), (14) all his verbal actions are preceded and followed by wisdom, (15) all his mental actions are preceded and followed by wisdom, (16) his wisdom and vision perceive the past without attachment or hindrance, (17) his wisdom and vision perceive the future without attachment or hindrance, and (18) his wisdom and vision perceive the present without attachment or hindrance.

In the context of Buddhist philosophy, one way to describe experience in terms of eighteen elements (eye, form, and eye consciousness; ear, sound, and ear consciousness; nose, smell, and nose consciousness; tongue, taste, and tongue consciousness; body, touch, and body consciousness; and mind, mental phenomena, and mind consciousness).

This also refers to the elements of the world, which can be enumerated as four, five, or six. The four elements are earth, water, fire, and air. A fifth, space, is often added, and the sixth is consciousness.

The essentially pure nature of mind is obscured and afflicted by various psychological defilements, which destroy the mind’s peace and composure and lead to unwholesome deeds of body, speech, and mind, acting as causes for continued existence in saṃsāra. Included among them are the primary afflictions of desire (rāga), anger (dveṣa), and ignorance (moha). It is said that there are eighty-four thousand of these negative mental qualities, for which the eighty-four thousand categories of the Buddha’s teachings serve as the antidote.

Kleśa is also commonly translated as “negative emotions,” “disturbing emotions,” and so on. The Pāli kilesa, Middle Indic kileśa, and Buddhist Hybrid Sanskrit kleśa all primarily mean “stain” or “defilement.” The translation “affliction” is a secondary development that derives from the more general (non-Buddhist) classical understanding of √kliś (“to harm,“ “to afflict”). Both meanings are noted by Buddhist commentators.

Morally virtuous or disciplined conduct and the abandonment of morally undisciplined conduct of body, speech, and mind. In a general sense, moral discipline is the cause for rebirth in higher, more favorable states, but it is also foundational to Buddhist practice as one of the three trainings (triśikṣā) and one of the six perfections of a bodhisattva. Often rendered as “ethics,” “discipline,” and “morality.”

Four gods who live on the lower slopes (fourth level) of Mount Meru in the eponymous Heaven of the Four Great Kings (Cāturmahā­rājika, rgyal chen bzhi’i ris) and guard the four cardinal directions. Each is the leader of a nonhuman class of beings living in his realm. They are Dhṛtarāṣṭra, ruling the gandharvas in the east; Virūḍhaka, ruling over the kumbhāṇḍas in the south; Virūpākṣa, ruling the nāgas in the west; and Vaiśravaṇa (also known as Kubera) ruling the yakṣas in the north. Also referred to as Guardians of the World or World Protectors (lokapāla, ’jig rten skyong ba).

The meditations on love (maitrī), compassion (karuṇā), joy (muditā), and equanimity (upekṣā), as well as the states of mind and qualities of being that result from their cultivation. They are also called the four abodes of Brahmā (caturbrahmavihāra).

In the Abhidharmakośa, Vasubandhu explains that they are called apramāṇa‍—meaning “infinite” or “limitless”‍—because they take limitless sentient beings as their object, and they generate limitless merit and results. Love is described as the wish that beings be happy, and it acts as an antidote to malice (vyāpāda). Compassion is described as the wish for beings to be free of suffering, and acts as an antidote to harmfulness (vihiṃsā). Joy refers to rejoicing in the happiness beings already have, and it acts as an antidote to dislike or aversion (arati) toward others’ success. Equanimity is considering all beings impartially, without distinctions, and it is the antidote to both attachment to pleasure and to malice (kāmarāgavyāpāda).

The four truths that the Buddha transmitted in his first teaching: (1) suffering, (2) the origin of suffering, (3) the cessation of suffering, and (4) the path to the cessation of suffering.

When the Buddhist teachings are classified according to their power to lead beings to an awakened state, a distinction is made between the teachings of the Lesser Vehicle (Hīnayāna), which emphasizes the individual’s own freedom from cyclic existence as the primary motivation and goal, and those of the Great Vehicle (Mahāyāna), which emphasizes altruism and has the liberation of all sentient beings as the principal objective. As the term “Great Vehicle” implies, the path followed by bodhisattvas is analogous to a large carriage that can transport a vast number of people to liberation, as compared to a smaller vehicle for the individual practitioner.

This term denotes the ontological status of phenomena, according to which they are said to possess existence in their own right‍—inherently, in and of themselves, objectively, and independent of any other phenomena such as our conception and labelling. The absence of such an ontological reality is defined as the true nature of reality, emptiness.

The name of the southern continent in Buddhist cosmology, which can signify either the known human world, or more specifically the Indian subcontinent, literally “the jambu island/continent.” Jambu is the name used for a range of plum-like fruits from trees belonging to the genus Szygium, particularly Szygium jambos and Szygium cumini, and it has commonly been rendered “rose apple,” although “black plum” may be a less misleading term. Among various explanations given for the continent being so named, one (in the Abhidharmakośa) is that a jambu tree grows in its northern mountains beside Lake Anavatapta, mythically considered the source of the four great rivers of India, and that the continent is therefore named from the tree or the fruit. Jambudvīpa has the Vajrāsana at its center and is the only continent upon which buddhas attain awakening.

The supernatural powers of a śrāvaka correspond to the first abhijñā: “Being one he becomes many, being many he becomes one; he becomes visible, invisible; goes through walls, ramparts and mountains without being impeded, just as through air; he immerses himself in the earth and emerges from it as if in water; he goes on water without breaking through it, as if on [solid] earth; he travels through the air crosslegged like a winged bird; he takes in his hands and touches the moon and the sun, those two wonderful, mighty beings, and with his body he extends his power as far as the Brahma world” (Śūraṃgamasamādhisūtra, trans. Lamotte 2003).

The great supernatural powers (maharddhi) of bodhisattvas are “causing trembling, blazing, illuminating, rendering invisible, transforming, coming and going across obstacles, reducing or enlarging worlds, inserting any matter into one’s own body, assuming the aspects of those one frequents, appearing and disappearing, submitting everyone to one’s will, dominating the supernormal power of others, giving intellectual clarity to those who lack it, giving mindfulness, bestowing happiness, and finally, emitting beneficial rays” (Śūraṃgamasamādhisūtra, trans. Lamotte 2003).

The bodhisattva Maitreya is an important figure in many Buddhist traditions, where he is unanimously regarded as the buddha of the future era. He is said to currently reside in the heaven of Tuṣita, as Śākyamuni’s regent, where he awaits the proper time to take his final rebirth and become the fifth buddha in the Fortunate Eon, reestablishing the Dharma in this world after the teachings of the current buddha have disappeared. Within the Mahāyāna sūtras, Maitreya is elevated to the same status as other central bodhisattvas such as Mañjuśrī and Avalokiteśvara, and his name appears frequently in sūtras, either as the Buddha’s interlocutor or as a teacher of the Dharma. Maitreya literally means “Loving One.” He is also known as Ajita, meaning “Invincible.”

For more information on Maitreya, see, for example, the introduction to Maitreya’s Setting Out (Toh 198).

Māra, literally “death” or “maker of death,” is the name of the deva who tried to prevent the Buddha from achieving awakening, the name given to the class of beings he leads, and also an impersonal term for the destructive forces that keep beings imprisoned in saṃsāra:

(1) As a deva, Māra is said to be the principal deity in the Heaven of Making Use of Others’ Emanations (paranirmitavaśavartin), the highest paradise in the desire realm. He famously attempted to prevent the Buddha’s awakening under the Bodhi tree‍—see The Play in Full (Toh 95), 21.1‍—and later sought many times to thwart the Buddha’s activity. In the sūtras, he often also creates obstacles to the progress of śrāvakas and bodhisattvas. (2) The devas ruled over by Māra are collectively called mārakāyika or mārakāyikadevatā, the “deities of Māra’s family or class.” In general, these māras too do not wish any being to escape from saṃsāra, but can also change their ways and even end up developing faith in the Buddha, as exemplified by Sārthavāha; see The Play in Full (Toh 95), 21.14 and 21.43. (3) The term māra can also be understood as personifying four defects that prevent awakening, called (i) the divine māra (devaputra­māra), which is the distraction of pleasures; (ii) the māra of Death (mṛtyumāra), which is having one’s life interrupted; (iii) the māra of the aggregates (skandhamāra), which is identifying with the five aggregates; and (iv) the māra of the afflictions (kleśamāra), which is being under the sway of the negative emotions of desire, hatred, and ignorance.

In this scripture wherever the term “mindset” (citta) appears alone (i.e., not in a compound like bodhicitta), it may refer to the mindset of awakening, or to a proper mindset directly related to it, or to an improper mindset antithetical to it, or to the immediate content of any of these three senses of the word mindset. See the introduction, i.92.

The term bhikṣu, often translated as “monk,” refers to the highest among the eight types of prātimokṣa vows that make one part of the Buddhist assembly. The Sanskrit term literally means “beggar” or “mendicant,” referring to the fact that Buddhist monks and nuns‍—like other ascetics of the time‍—subsisted on alms (bhikṣā) begged from the laity.

In the Tibetan tradition, which follows the Mūlasarvāstivāda Vinaya, a monk follows 253 rules as part of his moral discipline. A nun (bhikṣuṇī; dge slong ma) follows 364 rules. A novice monk (śrāmaṇera; dge tshul) or nun (śrāmaṇerikā; dge tshul ma) follows thirty-six rules of moral discipline (although in other vinaya traditions novices typically follow only ten).

The extreme philosophical view that rejects rebirth and the law of karma by considering that causes (and thus actions) do not have effects and that the self, being the same as one or all of the aggregates (skandhas), ends at death. Commonly translated as “nihilism” or, more literally, as “view of annihilation.” It is often mentioned along with its opposite view, the extreme of eternalism or permanence.

In Sanskrit, the term nirvāṇa literally means “extinguishment” and the Tibetan mya ngan las ’das pa literally means “gone beyond sorrow.” As a general term, it refers to the cessation of all suffering, afflicted mental states (kleśa), and causal processes (karman) that lead to rebirth and suffering in cyclic existence, as well as to the state in which all such rebirth and suffering has permanently ceased.

More specifically, three main types of nirvāṇa are identified. (1) The first type of nirvāṇa, called nirvāṇa with remainder (sopadhiśeṣanirvāṇa), is the state in which arhats or buddhas have attained awakening but are still dependent on the conditioned aggregates until their lifespan is exhausted. (2) At the end of life, given that there are no more causes for rebirth, these aggregates cease and no new aggregates arise. What occurs then is called nirvāṇa without remainder ( anupadhiśeṣanirvāṇa), which refers to the unconditioned element (dhātu) of nirvāṇa in which there is no remainder of the aggregates. (3) The Mahāyāna teachings distinguish the final nirvāṇa of buddhas from that of arhats, the nirvāṇa of arhats not being considered ultimate. The buddhas attain what is called nonabiding nirvāṇa (apratiṣṭhitanirvāṇa), which transcends the extremes of saṃsāra and nirvāṇa, i.e., existence and peace. This is the nirvāṇa that is the goal of the Mahāyāna path.

The term bhikṣuṇī, often translated as “nun,” refers to the highest among the eight types of prātimokṣa vows that make one part of the Buddhist assembly. The Sanskrit term bhikṣu (to which the female grammatical ending ṇī is added) literally means “beggar” or “mendicant,” referring to the fact that Buddhist nuns and monks‍—like other ascetics of the time‍—subsisted on alms (bhikṣā) begged from the laity. In the Tibetan tradition, which follows the Mūlasarvāstivāda Vinaya, a bhikṣuṇī follows 364 rules and a bhikṣu follows 253 rules as part of their moral discipline.

For the first few years of the Buddha’s teachings in India, there was no ordination for women. It started at the persistent request and display of determination of Mahāprajāpatī, the Buddha’s stepmother and aunt, together with five hundred former wives of men of Kapilavastu, who had themselves become monks. Mahāprajāpatī is thus considered to be the founder of the nun’s order.

The first of the four truths of the noble ones. The term “suffering” includes all essentially unsatisfactory experiences of life in cyclic existence, whether physical or mental. These comprise (1) the suffering of suffering, i.e., the physical sensations and mental experiences that are self-evident as suffering and toward which spontaneous feelings of aversion arise; (2) the suffering of change, i.e., all experiences that are normally recognized as pleasant and desirable, but which are nonetheless suffering in that persistent indulgence in these always results in changing attitudes of dissatisfaction and boredom; and (3) the suffering of the pervasive conditioning underlying the round of birth, aging, and death.

This term has three meanings: (1) the ultimate nature, (2) the experience of the ultimate nature, and (3) the quiescent state of a worthy one (arhat) to be avoided by bodhisattvas.

The term dhāraṇī has the sense of something that “holds” or “retains,” and so it can refer to the special capacity of practitioners to memorize and recall detailed teachings. It can also refer to a verbal expression of the teachings‍—an incantation, spell, or mnemonic formula‍—that distills and “holds” essential points of the Dharma and is used by practitioners to attain mundane and supramundane goals. The same term is also used to denote texts that contain such formulas.

The ancient capital of Magadha prior to its relocation to Pāṭaliputra during the Mauryan dynasty, Rājagṛha is one of the most important locations in Buddhist history. The literature tells us that the Buddha and his saṅgha spent a considerable amount of time in residence in and around Rājagṛha‍—in nearby places, such as the Vulture Peak Mountain (Gṛdhrakūṭaparvata), a major site of the Mahāyāna sūtras, and the Bamboo Grove (Veṇuvana)‍—enjoying the patronage of King Bimbisāra and then of his son King Ajātaśatru. Rājagṛha is also remembered as the location where the first Buddhist monastic council was held after the Buddha Śākyamuni passed into parinirvāṇa. Now known as Rajgir and located in the modern Indian state of Bihar.

According to most lists (specifically those of the Pāli and some Abhidharma traditions), the (three) roots of virtue or the roots of the good or wholesome states (of mind) are what makes a mental state good or bad; they are identified as the opposites of the three mental “poisons” of greed, hatred, and delusion. Actions based on the roots of virtue will eventually lead to future happiness. The Dharmasaṃgraha, however, lists the three roots of virtue as (1) the mind of awakening, (2) purity of thought, and (3) freedom from egotism (Skt. trīṇi kuśala­mūlāni | bodhi­cittotpādaḥ, āśayaviśuddhiḥ, ahaṃkāramama­kāraparityāgaśceti|).

A bodhisattva famous for his quest for the Dharma and for his devotion to the teacher. It is told that Sadāprarudita, in order to make offerings to the bodhisattva Dharmodgata and request the Prajñāpāramitā teachings, sets out to sell his own flesh and blood. After receiving a first set of teachings, Sadāprarudita waits seven years for the bodhisattva Dharmodgata, his teacher, to emerge from meditation. When he receives signs this is about to happen, he wishes to prepare the ground for the teachings by settling the dust. Māra makes all the water disappear, so Sadāprarudita decides to use his own blood to settle the dust. He is said to be practicing in the presence of Buddha Bhīṣma­garjita­nirghoṣa­svara. His name means "Ever Weeping", on account of the numerous tears he shed until he found the teachings.

His story is told in detail by the Buddha in The Perfection of Wisdom in Eighteen Thousand Lines (Toh 10, ch. 85–86), and can be found quoted in several works, such as The Words of My Perfect Teacher (kun bzang bla ma’i zhal lung) by Patrul Rinpoche.

Name of the ancient tribe in which the Buddha was born as a prince; their kingdom was based to the east of Kośala, in the foothills near the present-day border of India and Nepal, with Kapilavastu as its capital.

One of the principal śrāvaka disciples of the Buddha, he was renowned for his discipline and for having been praised by the Buddha as foremost of the wise (often paired with Maudgalyā­yana, who was praised as foremost in the capacity for miraculous powers). His father, Tiṣya, to honor Śāriputra’s mother, Śārikā, named him Śāradvatīputra, or, in its contracted form, Śāriputra, meaning “Śārikā’s Son.”

A mendicant whose encounter with the Buddha and acceptance of him as the tathāgata features in the Prajñāpāramitā sūtras as evidence that the Buddha’s omniscience is not something to be understood through signs or characteristics. Also known as Śreṇika Vatsagotra.

The three different renderings of his name in Tibetan‍—sde can, phreng ba can, and bzo sbyangs (which may correspond to Skt. Seniṣka, Prakniṣka, and Śaniṣka)‍—are taken as markers for three different Tibetan translations of the Aṣṭa­sāhasrikā­prajñā­pāramitā, as mentioned in the catalog of the Phukdrak (phug brag) Kangyur and the Thamphü (tham phud) of the Fifth Dalai Lama, Ngawang Lozang Gyatso.

The eighty secondary physical characteristics of a buddha and of other great beings (mahāpuruṣa), which include such details as the redness of the fingernails and the blackness of the hair. They are considered “minor” in terms of being secondary to the thirty-two major marks or signs of a great being.

The five Pure Abodes are the highest heavens of the Form Realm (rūpadhātu). They are called “pure abodes” because ordinary beings (pṛthagjana; so so’i skye bo) cannot be born there; only those who have achieved the fruit of a non-returner (anāgāmin; phyir mi ’ong) can be born there. A summary presentation of them is found in the third chapter of Vasubandhu's Abhidharmakośa, although they are repeatedly mentioned as a set in numerous sūtras, tantras, and vinaya texts.

The five Pure Abodes are the last five of the seventeen levels of the Form Realm. Specifically, they are the last five of the eight levels of the upper Form Realm‍—which corresponds to the fourth meditative concentration (dhyāna; bsam gtan)‍—all of which are described as “immovable” (akopya; mi g.yo ba) since they are never destroyed during the cycles of the destruction and reformation of a world system. In particular, the five are Abṛha (mi che ba), the inferior heaven; Atapa (mi gdung ba), the heaven of no torment; Sudṛśa (gya nom snang), the heaven of sublime appearances; Sudarśana (shin tu mthong), the heaven of the most beautiful to behold; and Akaniṣṭha (’og min), the highest heaven.

Yaśomitra explains their names, stating: (1) because those who abide there can only remain for a fixed amount of time, before they are plucked out (√bṛh, bṛṃhanti) of that heaven, or because it is not as extensive (abṛṃhita) as the others in the pure realms, that heaven is called the inferior heaven (abṛha; mi che ba); (2) since the afflictions can no longer torment (√tap, tapanti) those who reside there because of their having attained a particular samādhi, or because their state of mind is virtuous, they no longer torment (√tap, tāpayanti) others, this heaven, consequently, is called the heaven of no torment (atapa; mi gdung ba); (3) since those who reside there have exceptional (suṣṭhu) vision because what they see (√dṛś, darśana) is utterly pure, that heaven is called the heaven of sublime appearances (sudṛśa; gya nom snang); (4) because those who reside there are beautiful gods, that heaven is called the heaven of the most beautiful to behold (sudarśana; shin tu mthong); and (5) since it is not lower (na kaniṣṭhā) than any other heaven because there is no other place superior to it, this heaven is called the highest heaven (akaniṣṭha; ’og min) since it is the uppermost.

The assembly hall in the center of Sudarśana, the city in the Heaven of the Thirty-Three (Trāyastriṃśa). It has a central throne for Indra (Śakra) and thirty-two thrones arranged to its right and left for the other thirty-two devas that make up the eponymous thirty-three devas of Indra’s paradise. Indra’s own palace is to the north of this assembly hall.

The real nature, true quality, or condition of things. Throughout Buddhist discourse this term is used in two distinct ways. In one, it designates the relative nature that is either the essential characteristic of a specific phenomenon, such as the heat of fire and the moisture of water, or the defining feature of a specific term or category. The other very important and widespread way it is used is to designate the ultimate nature of all phenomena, which cannot be conveyed in conceptual, dualistic terms and is often synonymous with emptiness or the absence of intrinsic existence.

Tuṣita (or sometimes Saṃtuṣita), literally “Joyous” or “Contented,” is one of the six heavens of the desire realm (kāmadhātu). In standard classifications, such as the one in the Abhidharmakośa, it is ranked as the fourth of the six counting from below. This god realm is where all future buddhas are said to dwell before taking on their final rebirth prior to awakening. There, the Buddha Śākyamuni lived his preceding life as the bodhisattva Śvetaketu. When departing to take birth in this world, he appointed the bodhisattva Maitreya, who will be the next buddha of this eon, as his Dharma regent in Tuṣita. For an account of the Buddha’s previous life in Tuṣita, see The Play in Full (Toh 95), 2.12, and for an account of Maitreya’s birth in Tuṣita and a description of this realm, see The Sūtra on Maitreya’s Birth in the Heaven of Joy, (Toh 199).

Vajrapāṇi means “Wielder of the Vajra.” In the Pali canon, he appears as a yakṣa guardian in the retinue of the Buddha. In the Mahāyāna scriptures he is a bodhisattva and one of the “eight close sons of the Buddha.” In the tantras, he is also regarded as an important Buddhist deity and instrumental in the transmission of tantric scriptures.

The Gṛdhra­kūṭa, literally Vulture Peak, was a hill located in the kingdom of Magadha, in the vicinity of the ancient city of Rājagṛha (modern-day Rajgir, in the state of Bihar, India), where the Buddha bestowed many sūtras, especially the Great Vehicle teachings, such as the Prajñāpāramitā sūtras. It continues to be a sacred pilgrimage site for Buddhists to this day.

The term lokadhātu refers to a single four continent world-system illumined by a sun and moon, with a Mount Meru at its center and an encircling ring of mountains at its periphery, and with the various god realms above, thus including the desire, form, and formless realms.

The term can also refer to groups of such world-systems in multiples of thousands. A universe of one thousand such world-systems is called a chiliocosm (sāhasra­loka­dhātu, stong gi ’jig rten gyi khams); one thousand such chiliocosms is called a dichiliocosm (dvisāhasralokadhātu, stong gnyis kyi ’jig rten gyi khams); and one thousand such dichiliocosms is called a trichiliocosm (trisāhasra­loka­dhātu, stong gsum gyi 'jig rten gyi khams). A trichiliocosm is the largest universe described in Buddhist cosmology.

Literally, “to flow” or “to ooze.” Mental defilements or contaminations that “flow out” toward the objects of cyclic existence, binding us to them. Vasubandhu offers two alternative explanations of this term: “They cause beings to remain (āsayanti) within saṃsāra” and “They flow from the Summit of Existence down to the Avīci hell, out of the six wounds that are the sense fields” (Abhidharma­kośa­bhāṣya 5.40; Pradhan 1967, p. 308). The Summit of Existence (bhavāgra, srid pa’i rtse mo) is the highest point within saṃsāra, while the hell called Avīci (mnar med) is the lowest; the six sense fields (āyatana, skye mched) here refer to the five sense faculties plus the mind, i.e., the six internal sense fields.
