Mbh 1.172.6a

“The Gandharva replied, ‘I have been vanquished by thee, I shall, therefore, abandon my former name Angaraparna (the blazing vehicle). In name alone, O friend, I should not be boastful when my pride in my strength hath been overcome: I have been fortunate in that I have obtained thee; O Arjuna, that wielder of celestial weapons! I like to impart to thee the power of (producing) illusions which Gandharvas alone have. My excellent and variegated chariot hath been burnt by means of thy fiery weapon. I who had formerly been called after my excellent chariot should now be called after my burnt chariot. The science of producing illusions that I have spoken of was formerly obtained by me by ascetic penances. That science I will today impart to the giver of my life-thy illustrious self! What good luck doth he not deserve who, after overcoming a foe by his might, giveth him life when that foe asketh for it? This science is called Chakshushi. It was communicated by Manu unto Soma and by Soma unto Viswavasu, and lastly by Viswavasu unto me. Communicated by my preceptor, that science, having come unto me who am without energy, is gradually becoming fruitless. I have spoken to thee about its origin and transmission. Listen now to its power! One may see (by its aid) whatever one wisheth to see, and in whatever way he liketh (generally or particularly). One can acquire this science only after standing on one leg for six months. I shall however, communicate to thee this science without thyself being obliged to observe any rigid vow. O king, it is for this knowledge that we are superior to men. And as we are capable of seeing everything by spiritual sight, we are equal to the gods. O best of men, I intend to give thee and each of thy brothers a hundred steeds born in the country of the Gandharvas. Of celestial colour and endued with the speed of the mind, those horses are employed in bearing the celestial, and the Gandharvas.
