A mountain in North India, on the Upper Ganges. There, for some time, lived the Thera Sambhúta Sánavási, and it was there that Yasa Kákandakaputta saw him. The meeting of arahants to discuss what measures should be taken against the Vesálí monks was also held there, and at the meeting were present monks from the Western country and from Avanti-Dakkhinápatha (Vin.ii.298-9).
Moggaliputta lived in Ahogangá all alone for seven years, prior to the Third Council for which he was awaiting the right time (Mhv.v.233; see also Vin. Texts, ii.146, n.1. The Mbv., p.106, says upari Gangáya; see also Sp.i.57). The Mahávamsa describes it as being "further up the Ganges" (uddham Gangáya).
Moggaliputta Tissa came from Ahogangá to Pátaliputta on a raft. Sp.i.57.
