Mbh 1.28.2a

“Sauti said, ‘Garuda, thus addressed by the snakes, then said unto his mother, ‘I shall go to bring amrita, I desire to eat something in the way. Direct me to it.’ Vinata replied, ‘In a remote region in the midst of the ocean, the Nishadas have their fair home. Having eaten the thousands of Nishadas that live there, bring thou amrita. But let not thy heart be ever set on taking the life of a Brahmana. Of all creatures a Brahmana must not be slain. He is, indeed, like fire. A Brahmana, when angry, becomes like fire or the Sun, like poison or an edged weapon. A Brahmana, it has been said, is the master of all creatures.

Indeed, a brahmana is the first-born of all creatures, the foremost of the four orders, the father and the master of all.’” Garuda then asked, ‘O mother, of what form is a Brahmana, of what behaviour, and of what prowess? Doth he shine like fire, or is he of tranquil mien?

A Brahmana must never be slain by thee even in anger.’ And Vinata out of affection for her son, again told him these words, ‘Him shouldst thou know as a good Brahmana who would not be digested in thy stomach.’ Although she knew the incomparable strength of her son, yet she blessed him heartily, for, deceived by the snakes, she was very much afflicted by woe. And she said.
