"Jaratkaru, thus addressed, consoling Vasuki, the king of the snakes, at length replied, saying, 'Asked by me about offspring, the high-souled and mighty ascetic said, 'There is,'--and then he went away. I do not remember him to have ever before speak even in jest aught that is false. Why should he, O king, speak a falsehood on such a serious occasion? He said, 'Thou shouldst not grieve, O daughter of the snake race, about the intended result of our union. A son shall be born to thee, resplendent as the blazing sun.' O brother, having said this to me, my husband of ascetic wealth went away--Therefore, let the deep sorrow cherished in thy heart disappear.'
