Part 3 - The Prajñā and the teaching of the Dharma

The Dharma of the Buddhas is immense, like an ocean. According to the dispositions of beings, it is preached in various ways:^[1] sometimes it speaks of existence and sometimes of non-existence, of eternity or of impermanence, of suffering or of bliss, of self or non-self; sometimes it teaches the diligent practice of the threefold activity [of body, speech and mind] that embraces all the good dharmas (sarvakuśaladharmasaṃgrāhaka), sometimes it teaches that all dharmas are inactive by essence. Such are the multiple and various teachings: the ignorant who hear them take them to be a perverse error, but the wise man who enters into the threefold teaching of the Dharma (trividha dharmaparyāya) knows that all the Buddha’s words (buddhavacana) are the true Dharma (saddharma) and do not contradict one another.

[192b] What are these three teachings (paryāya)? – 1. The teaching of the Piṭaka; 2. the teaching of the Abhidharma; 3. the teaching of emptiness (śūnya).
