In Theravāda Buddhism, pariyatti, paṭipatti, paṭivedha (Pāli; "Learning; practicing; realizing") is the educational concept consisting of three progressive stages culminating in full understanding of the Buddha's teaching.
[2] In contrast to Mahāyāna and Vajrayāna, Theravāda tends to be conservative in matters of the theoretical study of the doctrine (pariyatti) and monastic discipline (vinaya).
[3] One element of this conservatism is the fact that Theravāda rejects the authenticity of the Mahayana sutras (which appeared c. 1st century BCE onwards).
One has to practise (paṭipatti) these teachings which lead to paṭivedha, that is the path (magga) and fruition (phala) states and Nibbana.
[6] U Ba Khin states, "When one meets with a Buddha, arahats and noble ariyas, it is truly possible to practise morality, concentration and insight and attain the paths and fruits of awakening by merely listening to and following their teachings, which are given based on firsthand personal experience and knowledge.
