1. Ákásagangá.-The river that flows southward from the Anotatta Lake receives, in its different stages, various names. That part of it which flows sixty leagues through the air is called Ákásagangá (SnA.ii.439; MA.586, etc.). The Buddha's discourse on various topics (pakinnakakathá) is like the downward flow of the Ákásagangá (AA.i.94; DhA.iii.360); so also is the eloquence of clever preachers (E.g., DhA.iv.18; J.ii.65).
The fine clay to be found in the area (thirty yojanas in extent) over which the Ákásagangá falls to earth, is called, on account of its fineness, "butter clay" (navaníta-mattiká). This clay was brought by arahant sámaneras to be spread over the foundation of the Mahá Thúpa in Anurádhapura (Mhv.xxix.5f). The spot where it is found is called Tintasísakola. MT.515
2. Ákásagangá.-A vast channel built by Parakkamabáhu I. to bring water from the Káragangá to the Parakkamammudda. Cv.lxxix.25.
