The Questions of Brahma­viśeṣacintin

In this sūtra, the Buddha Śākyamuni and a number of the bodhisattvas, elders, and gods in his assembly engage in a lively exchange clarifying many key points of the Dharma from the perspective of the Mahāyāna, including the four truths, the origin of saṃsāra, and the identity of the buddhas, while praising the qualities of the paragons of the Mahāyāna, the bodhisattvas.
