Translation:
The son of Saṅkalpā was known as Saṅkalpa, and from him lust was born. The sons of Vasu were known as the eight Vasus. Just hear their names from me: Droṇa, Prāṇa, Dhruva, Arka, Agni, Doṣa, Vāstu and Vibhāvasu. From Abhimati, the wife of the Vasu named Droṇa, were generated the sons named Harṣa, Śoka, Bhaya and so on.
