Probably the headwaters of the Dṛṣadvati have changed course eastwards and joined the Yamuna. Viṣṇupurāṇa says that when the family of Viśvāmitra reached Ayōdhya, destitute and hungry, it was Triśanku and later his son Hariścandra who fed them and gave them shelter. The enmity between Viśvāmitra with their chief priest Vaśiṣṭha also belongs to the same period. Mārkanḍēya Purāṇa tells us about the battle that took place between them during Hariścandra’s reign.
