 Not all Buddhist texts from this period are hostile to argumentation. Two works contain short passages with lists and classificatory definitions of terms pertaining to debate. One is the Saṃdhi-nirmocana-sūtra (Aphorisms on release from bondage), of unknown authorship, whose original Sanskrit has been lost, but whose translations into Tibetan and Chinese have been preserved. (See Yoshimizu 2010.) The other is the Abhidharma-samuccaya (Compendium of the higher teachings), a text usually attributed to the Buddhist thinker, Asaṅga (5th century ce), whose fifth chapter has a section, its seventh, often referred to as Vāda-viniścaya (Settling on what debate is), also devoted to debate.
