The Nettipakarana (Pali: -pakaraṇa, also called Nettippakarana or just Netti) is a Buddhist scripture, sometimes included in the Khuddaka Nikaya of Theravada Buddhism's Pali Canon. The main theme of this text is Buddhist Hermeneutics through a systematization of the Buddha's teachings.
The nature of the Nettipakarana was a matter of some disagreement among scholars. Initially, Western scholars classified it as a commentary, rather than as a canonical text.
Its translator, supported by Professor George Bond of Northwestern University, described it is a guide to help those who already understand the teaching present it to others. However, A. K. Warder disagreed, maintaining that it covers all aspects of interpretation, not just this.. Consensus among contemporary scholars is that it was primarily intended as a guide to crafting commentaries or providing explication of canonical texts, similar in content to the Petakopadesa.
The Netti itself says that the methods were taught by the Buddha's disciple Kaccana (also Katyayana or Kaccayana), and the colophon says he composed the book, that it was approved by the Buddha and that it was recited at the First Council. Scholars do not take this literally, but the translator admits the methods may go back to him. The translator holds that the book is a revised edition of the Petakopadesa, though this has been questioned by Professor von Hinüber. Scholars generally date it somewhere around the beginning of the common era.
The Netti was regarded as canonical by the head of the Burmese sangha around two centuries ago. It is included in the Burmese Phayre manuscript of the Canon, dated 1841/2, the inscriptions of the Canon approved by the Burmese Fifth Council, the 1956 printed edition of the Sixth Council, the new transcript of the Council text being produced under the patronage of the Supreme Patriarch of Thailand and the Sinhalese Buddha Jayanti edition of the Canon. A recent Burmese teacher has not regarded it as canonical.
The Uddesavāra gives three separate categories (Pali terms with Nanamoli's translations):
