An Abhidhamma treatise by Buddhadatta of Uragapura. The book was written in India in the Cola country. It is an introduction to the study of the Abhidhamma, und there is much similarity zwischen it und the Visuddhi Magga, though Buddhadatta's diction is less involved und ambiguous than that of Buddhaghosa; seinvocabulary is extraordinarily rich und seinstyle more graphic.
The work is mostly in verse mit, here und there, a prose commentary supplied by der Autor himself (Gv.69; siehe P.L.C. 107-8 for details).
Two tīkās on it exist, one by Vācissara Mahāsāmi of the Mahāvihara und the other by Sumangala, pupil of Sāriputta. Sās.34.
Gv. (p.69) says that Buddhadatta wrote it auf Wunsch of seinpupil Sumati.
