A country north of the river Mahī, evidently a part of Anga on the other side of that river (Angā eva so janapado; Gangāya [Mahāmahīgangāya] pana yā uttarena āpo, tāsam avidūrattā Uttarāpati vuccati) (SnA.ii.437).
It was here, in the village āpana, that the Buddha was staying when the Jatila Keniya came to see him; here also was preached the Sela Sutta (Sn.102f). From Bhaddiya (in Anga), (DhA.i.384) the Buddha went to Anguttārapa and thence to āpana (Vin.i.243-5; DhA.iii.363).
The country was probably rich because we find as many as 1,250 monks accompanying the Buddha on his tour (Sn.102f).
Other suttas preached here are the Potaliya (M.i.359), and the Latukikopama (M.i.447).
Apana seems to have been the chief township, because it is always mentioned in connection with Anguttarāpa.
