tatobhavadvyāsarūpī sa viṣṇuścaturvāraṃ rāghavāsyāpi pūrṇaḥ /
parāśarātsatyavatyāṃ babhūva pailādibhirvedabhāgāṃśca kartum //

Then that Viṣṇu, having the form of Vyāsa, was complete four times for the descendant of Raghu; / he was born from Parāśara upon Satyavatī in order to make divisions of the Veda along with Paila and the others.
