Petakopadesa
The Petakopadesa (petakopadesa: "Pitaka-Disclosure") is a Buddhist scripture, sometimes included in the Pāli Canon of Theravada Buddhism.
Translation: Pitaka-Disclosure, tr Nanamoli, 1964, Pali Text Society, Bristol.
The nature of this book is a matter of some disagreement among scholars. The translator, supported by Professor George Bond of Northwestern University, 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.
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.
The text of the book as handed down in manuscript is very corrupt. This book was regarded as canonical by the head of the Burmese sangha about two centuries ago. It is included in the inscriptions of the Canon approved by the Burmese Fifth Council and in the printed edition of the Sixth Council text.
The Petakopadesa deals with the textual and the exegetical methodology. It is nothing but a different manipulation of the subject-matter discussed in the Nettipakarana. In some places there are quotations from the Tipitaka. B.C. Law says, “its importance lies also in the fact that in places it has quoted the Pāli canonical passages mentioning the sources by such names as Samyuttaka (Samyutta Nikāya) and Ekuttaraka (Ekuttara or Anguttara Nikāya)”. The Petakopadesa describes the cattāri ariyasaccāni or the Four Noble Truths as the central theme or the essence of Buddhism.
