"Vaisampayana said, 'O king, the great sage Gautama had a son named Saradwat. This Saradwat was born with arrows (in hand). O oppressor of foes, the son of Gautama exhibited great aptitude for the study of the science of weapons, but none for the other sciences. Saradwat acquired all his weapons by those austerities by which Brahmanas in student life acquire the knowledge of Vedas. Gautama (the son of Gotama) by his aptitude for the science of weapons and by his austerities made Indra himself greatly afraid of him. Then, O thou of Kuru's race, the chief of the gods summoned a celestial damsel named Janapadi and sent her unto Gautama, saying, 'Do thy best to disturb the austerities of Gautama.' Repairing unto the charming asylum of Saradwat, the damsel began to tempt the ascetic equipped with bow and arrows. Beholding that Apsara, of figure unrivalled on earth for beauty, alone in those woods and clad in a single piece of cloth, Saradwat's eyes expanded with delight. At the sight of the damsel, his bow and arrows slipped from his hand and his frame shook all over with emotion; but possessed of ascetic fortitude and strength of soul, the sage mustered sufficient patience to bear up against the temptation. The suddenness, however, of his mental agitation, caused an unconscious emission of his vital fluid. Leaving his bow and arrows and deer-skin behind, he went away, flying from the Apsara. His vital fluid, however, having fallen upon a clump of heath, was divided into two parts, whence sprang two children that were twins.
