pakṣiṇa ūcuḥ
vipulasvāniti khyātaḥ prāgāsīnmunisattamaḥ /
tasya putradvayaṃ jajñe sukṛṣastumburustathā //

The birds spoke:
“There was of yore a most virtuous Muni named Vipulasvat. To him were born two sons Sukṛṣa and Tumburu. We are the four sons of soul-subdued Sukṛṣa; to that Ṛṣi we were ever submissive in reverence, religious practices and faith. As he desired, who was diligent in the performance of austerities, and who constantly kept his organs under control, we at once produced fuel, flowers and everything else, and whatever was needed for sustenance.
