Then beholding the boy and the girl, the daughter-in-law of Prishata, desiring to have them, approached Yaja and said, 'Let not these know any one else except myself as their mother.' Yaja, desiring to do good unto the king said, 'So be it!'

And they also said, 'Because this daughter is so dark in complexion, she should be called Krishna (the dark).'
