In general, the second of the three trainings (triśikṣā), and in this text and others the second of five qualities of the Saṅgha that are also described in other texts as the five undefiled (or beyond-worldly) aggregates (skandha) characteristic of noble ones.

In a general sense, samādhi can describe a number of different meditative states. In the Mahāyāna literature, in particular in the Prajñāpāramitā sūtras, we find extensive lists of different samādhis, numbering over one hundred.

In a more restricted sense, and when understood as a mental state, samādhi is defined as the one-pointedness of the mind (cittaikāgratā), the ability to remain on the same object over long periods of time. The Drajor Bamponyipa (sgra sbyor bam po gnyis pa) commentary on the Mahāvyutpatti explains the term samādhi as referring to the instrument through which mind and mental states “get collected,” i.e., it is by the force of samādhi that the continuum of mind and mental states becomes collected on a single point of reference without getting distracted.
