23. When the colloquy has been held, the Adhvaryu enters the (Havirdhana), and draws Prajapati’s (first) Mahiman cup (of Soma) in a gold vessel. The Puroruc formula thereof is (Vajasaneyi Samhita XXIII, 1; Rig-v. X, 121, 1), “The golden germ was first produced . . .” And its Puro'nuvakya is (Vajasaneyi Samhita XXIII, 63), “Of good nature, self-existent at first (within the great ocean: I verily place the right germ whence is born Prajapati).”—“May the Hotri offer to Prajapati: [of the Mahiman Soma (cup); may he relish, may he drink the Soma! Hotri, utter the offering-formula!]” is the Praisha (ib. 64). The Hotri utters the offering-formula (ib. 65), “O Prajapati, none other than thee hath encompassed all these forms . . . ;” and as the Vashat is pronounced, he (the Adhvaryu) offers with (Vajasaneyi Samhita XXIII, 2), “What greatness of thine there hath been in the day, and the year, [what greatness of thine there hath been in the wind and the air; what greatness of thine there hath been in the heavens and the sun, to that greatness of thine, to Prajapati, hail, to the gods!]” He does not repeat the Vashat, for he offers the cup of Soma all at once.
