ity utsasarja svaṁ dehaṁ
nimir adhyātma-kovidaḥ
mitrā-varuṇayor jajñe
urvaśyāṁ prapitāmahaḥ
iti - thus; utsasarja - gave up; svam - his own; deham - body; nimiḥ - Mahārāja Nimi; adhyātma-kovidaḥ - fully conversant with spiritual knowledge; mitrā-varuṇayoḥ - from the semen of Mitra and Varuṇa (discharged from seeing the beauty of Urvaśī); jajñe - was born; urvaśyām - through Urvaśī, a prostitute of the heavenly kingdom; prapitāmahaḥ - Vasiṣṭha, who was known as the great-grandfather.
Mitra and Varuṇa chanced to meet Urvaśī, the most beautiful prostitute of the heavenly kingdom, and they became lusty. Because they were great saints, they tried to control their lust, but they could not do so, and thus they discharged semen. This semen was kept carefully in a waterpot, and Vasiṣṭha was born from it.
