According to Buddhist tradition, one who is worthy of worship (pūjām arhati), or one who has conquered the enemies, the mental afflictions (kleśa-ari-hata-vat), and reached liberation from the cycle of rebirth and suffering. It is the fourth and highest of the four fruits attainable by śrāvakas. Also used as an epithet of the Buddha.

One of the “eight close sons of the Buddha,” he is also known as the bodhisattva who embodies compassion. In certain tantras, he is also the lord of the three families, where he embodies the compassion of the buddhas. In Tibet, he attained great significance as a special protector of Tibet, and in China, in female form, as Guanyin, the most important bodhisattva in all of East Asia.

Yeshé Dé (late eighth to early ninth century) was the most prolific translator of sūtras into Tibetan. Altogether he is credited with the translation of more than one hundred sixty sūtra translations and more than one hundred additional translations, mostly on tantric topics. In spite of Yeshé Dé’s great importance for the propagation of Buddhism in Tibet during the imperial era, only a few biographical details about this figure are known. Later sources describe him as a student of the Indian teacher Padmasambhava, and he is also credited with teaching both sūtra and tantra widely to students of his own. He was also known as Nanam Yeshé Dé, from the Nanam (sna nam) clan.

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.

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.

A cosmic period of time, sometimes equivalent to the time when a world system appears, exists, and disappears. According to the traditional Abhidharma understanding of cyclical time, a great eon (mahākalpa) is divided into eighty lesser eons. In the course of one great eon, the universe takes form and later disappears. During the first twenty of the lesser eons, the universe is in the process of creation and expansion; during the next twenty it remains; during the third twenty, it is in the process of destruction; and during the last quarter of the cycle, it remains in a state of empty stasis. A fortunate, or good, eon (bhadrakalpa) refers to any eon in which more than one buddha appears.

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.”

One of the principal śrāvaka disciples of the Buddha, paired with Śāriputra. He was renowned for his miraculous powers. His family clan was descended from Mudgala, hence his name Maudgalyā­yana, “the son of Mudgala’s descendants.” Respectfully referred to as Mahā­maudgalyā­yana, “Great Maudgalyāyana.”

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).

Mañjuśrī is one of the “eight close sons of the Buddha” and a bodhisattva who embodies wisdom. He is a major figure in the Mahāyāna sūtras, appearing often as an interlocutor of the Buddha. In his most well-known iconographic form, he is portrayed bearing the sword of wisdom in his right hand and a volume of the Prajñā­pāramitā­sūtra in his left. To his name, Mañjuśrī, meaning “Gentle and Glorious One,” is often added the epithet Kumārabhūta, “having a youthful form.” He is also called Mañjughoṣa, Mañjusvara, and Pañcaśikha.
