They finally reached the banks of the Sarasvati River where they saw the forest of Kamyaka, the favourite haunt of ascetics, situated on a level and wild plain on the banks of the Sarasvati abounding in birds and deer . There the Pandavas lived in an ascetic asylum . It took three days for Pandavas to reach the Kamyaka forest, setting out from Hastinapura, on their chariots . </P> <P> In the Rigveda there is also mention of a river named Aśvanvatī along with the river Drishadvati .
