殑伽（上疑等反下魚佉反梵語也舊云恒河是也即無熱惱大池流出四河南面一也旋流一匝流入南海者涅盤經中恒河女神也案殑伽河神名因神彰名也慧菀慧琳皆作此說）。

殑伽 (Gaṅgā: the upper character has the fanqie 疑等; the lower character has the fanqie 魚佉; this is Sanskrit; formerly written 恒河; it is one of the four rivers flowing out of the great lake devoid of afflictions [Lake Anavatapta], namely the southern one; the one that circles once and empties into the Southern Ocean is the Gaṅgā River goddess in the Mahāparinirvāṇa-sūtra; note: Gaṅgā is the name of the river goddess, and the river is named after the goddess; both Huiyuan and Huilin offer this explanation).
