Drishadvati River

"If the river Drsadvati is full of water, they should perform the Aponaptriya Isti near its confluence (in the Sarasvati). Dhanamjaya maintains that it may be performed there, even if it (the Drsadvati) has no water."

"He set thee in the earth’s most lovely station, in Iḷā’s place, in days of fair bright weather. On man, on Āpayā, Agni! on the rivers Dṛṣadvati, Sarasvatī, shine richly."

"That land, created by the gods, which lies between the two divine rivers Sarasvati and Drishadvati, the (sages) call Brahmavarta."
