Vaishampayana continued, "In days of yore, O monarch, there was an intelligent sage of great ascetic merit. He was celebrated by the name of Dadhica. Possessing a complete control over his senses, he led the life of a brahmacari. In consequence of his excessive ascetic austerities Shakra was afflicted with a great fear. The sage could not be turned (away from his penance) by the offer of even diverse kinds of rewards. At last the chastiser of Paka, for tempting the sage, despatched unto him the exceedingly beautiful and celestial apsara, by name Alambusa. Thither where on the banks of the Sarasvati the high-souled sage was engaged in the act of gratifying the gods, the celestial damsel named above, O monarch, made her appearance. Beholding that damsel of beautiful limbs, the vital seed of that ascetic of cleansed soul came out. It fell into the Sarasvati, and the latter held it with care. Indeed, O bull among men, the River, beholding that seed, held it in her womb. In time the seed developed into a foetus and the great river held it so that it might be inspired with life as a child. When the time came, the foremost of rivers brought forth that child and then went, O lord, taking it with her, to that rishi.
