nāsāpuṭābhyāmutsṛṣṭaṃ paro 'yamiti śaṅkayā
tadretasas tato jātāv aśvināv iti niścitam //

The sun, after thus getting his power modified by Viśvakarmâ, went out in the form of a horse and enjoyed himself in the company of Saṃjñâ, who, not recognising him and taking him for another person, became terrified, but was helpless; she consequently ejected the semen virile through her nostrils, out of which Aśvinikumâras, called otherwise Nâsatyas and Dasras, were born. They are called Nâsatyas, because they were born from the nose (nâsa), and Dasras, because they were born as Sons. Afterwards, Saṃjñâ recognised her Lord and became pleased, and went with her Lord in a vimâna to heaven.—34-37. Note.—‘Aśvarupeṇa’ means in the form of a horse--which implies that the Sun being overpowered with passion ran with the speed of a horse to enjoy himself in the company of Saṃjñâ. ‘Manasâkṣobham’ = was agitated in mind, because she could not recognise her Lord at the first sight. She met the Sun after a long time, and quite unexpectedly, and then there was a great difference in his features, as his power was moderated by Viśvakarmâ. The Sun of course recognised Saṃjñâ, and mixed with her in the usual way. Saṃjñâ, being overpowered, became helpless, but was very much agitated in mind.
