The Mahabharata/Book 1: Adi Parva…
“ If thou also diest, I shall not be able to bear my life.' Then Sukra said, 'O son of Vrihaspati, thou art, indeed, one already crowned with success, because Devayani regards thee so well. Accept the science that I will today impart to thee, if, indeed, thou be not Indra in the form of Kacha. None can come out of my stomach with life. A Brahmana, however, must not be slain, therefore, accept thou the science I impart to thee. Start thou into life as my son. ”
