The performance of austerity by Parāśara on Mount Maināka for the sake of offspring at the behest of Vasiṣṭha. The birth of Vyāsa from Parāśara upon Kālī. The birth of Śuka from Vyāsa; an account of Śuka's lineage as four sons and one daughter. The request for assistance from Sarasvatī by Viśvāmitra desiring to seize Vasiṣṭha, his enmity remaining unabated even after the slaughter of the hundred sons. The carrying away of Vasiṣṭha from his hermitage by the force of Sarasvatī's current. The turning of Sarasvatī's water into blood due to Viśvāmitra's curse. Viśvāmitra's desire to slay Vasiṣṭha. A fierce clash between the two. The mutual acceptance of friendship through the abandonment of their growing enmity at the entreaty of the gods along with the seers. Sarasvatī's waters becoming clear again.
