And the queen of rivers, too, seeing king Mahabhisha lose his firmness, went away, thinking of him wishfully. And on her way, she saw those dwellers in heaven, the Vasus, also pursuing the same path. And the queen of rivers beholding them in the predicament, asked them, 'Why look ye so dejected? Ye dwellers in heaven, is everything right with you?'

Therefore, O river, thyself becoming a human female make us the Vasus, thy children. O amiable one, we are unwilling to enter the womb of any human female.' Thus addressed, the queen of rivers told them, 'Be it so and asked them, 'On earth, who is that foremost of men whom ye will make your father?'
