The Commentary to the Anguttara Nikaya is called
Manorathapurani, or "The Wish Fulfiller" in Pali. It was compiled in 500 AD by
Ven. Buddhaghosa based on a much older commentarial tradition. This Collection
of Discourses, Anguttara Nikaya, containing 9557 short suttas is divided into
eleven divisions known as nipatas. Each nipata is divided again into groups
called vaggas which usually contain ten suttas. The discourses are arranged in
progressive numerical order, each nipata containing suttas with items of dhamma,
beginning with one item and moving up by units of one till there are eleven
items of dhamma in each sutta of the last nipata. This one-volume complete
edition of the Anguttara Nikaya commentary constitutes an important source book
on Buddhist psychology and ethics providing essential features concerning the
theory and practice of the Dhamma as understood by the commentarial Pali
tradition.
