Vaṃśānuvārṇana and the Transition to the Fourth (Upasaṃhāra) Pada
भूताभवादिनः शक्तास्त्रयो वेदाः प्रवादिनाम् / अग्नीध्रः काश्यपश्चैव पौलस्त्यो मागधश्च यः
bhūtābhavādinaḥ śaktāstrayo vedāḥ pravādinām / agnīdhraḥ kāśyapaścaiva paulastyo māgadhaśca yaḥ
Mighty are those who expound bhūta-ābhava, the arising of beings; for the proclaimers, the three Vedas stand as pramāṇa. They are Agnīdhra, Kāśyapa, Paulastya, and also Māgadha.
