tato 'śvarūpadhṛgbhānuruttarānagamat kurūn /
tadṛśe tatra saṃjñāñca vaḍavārūpadhāriṇīm //

Then assuming a horse's form the Sun went to the Northern Kurus, and saw Sañjñā there disguised in mare’s shape. And she, seeing him approaching and afraid of a strange male, went towards him face to face, intent on guarding her rear. And thereupon as the two met there and joined their noses, two sons issued from the mare’s mouth, Nāsatya and Dasra; and at the termination of the flow of semen Revanta was born, bearing sword, shield and armour, mounted on horseback, furnished with arrows and quiver. Then the Sun displayed his own peerless form, and she gazing upon his true form felt a keen joy; and the Sun, the robber of the waters, brought home this his loving wife Sañjñā restored to her own shape.
