Ākāsagaṅgā untranslated

Ākāsagaṅgā. A vast channel built by Parakkamabāhu I. to bring water from the Kāragaṅgā to the Parakkamasamudda. Cv.lxxix.25.

Ākāsagaṅgā. 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 Ākāsagaṅgā (Snp-a.ii.439; MN­a.586, etc.). The Buddha’s discourse on various topics (pakiṇṇakakathā) is like the downward flow of the Ākāsagaṅgā (AN­a.i.94; Dhp­a.iii.360); so also is the eloquence of clever preachers (e.g., Dhp­a.iv.18; Ja.ii.65).

The fine clay to be found in the area (thirty yojanas in extent) over which the Ākāsagaṅgā falls to earth is called, on account of its fineness, “butter clay” (navanīta-mattikā). This clay was brought by Arahant sāmaṇeras to be spread over the foundation of the Mahā Thūpa in Anurādhapura (Mhv.xxix.5f). The spot where it is found is called Tintasīsakola. Mhv­ṭ.515
