Moreover he should say, 'Thou art the mouth; may I become the mouth'; the Bahiṣpavamāna is the mouth of the sacrifice; the head among his own he becomes, the chief of his own he becomes, who knows thus. An Asura woman, named Long Tongue, licked the morning pressing of the gods; it became drunk. The gods sought to remedy it; they said to Mitra and Varuṇa, 'Do ye remove this (intoxication).' They replied, 'Be it so; let us choose a boon from you.' 'Choose' (they said). They chose this boon, the milk mess of the morning pressing. This is their fixed portion, for it is chosen as a boon by the two. Thus what by her was made intoxicated, as it were, is made perfect by this (milk mess), for by it the two removed what was intoxicated as it were.
