Anguttara Nikaya, or «The Numerical Discourses of the Buddha», — is the fourth of the four major collections of the Sutta Pitaka of the Pali Canon. It consists of 11 nipatas, or books, which in total contain almost ten thousand short suttas. However, most of them are repetitions with minor changes, so there are about four thousand unique texts. At the core of the Anguttara Nikaya is a numerical scheme, in which suttas containing a specific number of points are included in the corresponding book. This facilitated easier memorization and mastery of the material in ancient times,
when writing was just beginning to emerge, and all teachings were transmitted orally.
This edition of the AN is divided into four volumes. The last, fourth volume contains the Book of Nine, the Book of Ten, and the Book of Eleven. The themes of the suttas cover a wide range of aspects of Buddhist teaching.
