The Petakopadesa (peṭakopadesa) is a Buddhist scripture, sometimes included in the Khuddaka Nikaya of the Pali Canon of Theravada Buddhism.

The nature of this book is a matter of some disagreement among scholars. The translator, supported by Professor George Bond of Northwestern University,[1] holds it is a guide to those who understand the teaching in presenting it to others. However, A. K. Warder, Professor Emeritus of Sanskrit in the University of Toronto, maintains that it covers all aspects of interpretation, not just that.[2]

The text is often connected to another para-canonical text, the Nettipakaraṇa. Oskar von Hinüber suggests that both of these texts originated from outside the Theravada tradition as handbooks on the interpretation of the sutras.[3]

According to the chapter colophons, the book was composed by the Buddha's disciple Kaccana (or Kaccayana). Scholars do not take this literally, though the translator mentions that the methods may go back to him. Scholars tend to give dates around the beginning of the common era.[citation needed]

The text of the book as handed down in manuscript is very corrupt.[citation needed]

This book was regarded as canonical by the head of the Burmese sangha about two centuries ago.[4] It is included in the inscriptions of the Canon approved by the Burmese Fifth Council[5] and in the printed edition of the Sixth Council text.[6]

However, the translator says this last title is a mistake for "moulding of the guidelines", the title given at the end.
