Buddhavacana, from Pali and Sanskrit, means "the Word of the Buddha." It refers to the works accepted within a tradition as being the teachings of the Buddha. All traditions recognize certain texts as buddhavacana which make no claim to being the actual words of the historical Buddha, such as the Theragāthā and Vimalakīrti Nirdeśa Sūtra.
