The first layer is the Soma-sacrifice; the second the Râgasûya as prior to the consecrations; the third the Vâgapeya; the fourth the Asvamedha (horse-sacrifice); and the fifth the Agnisava. Then the sâmans he sings around the built (altar) are the Mahâvrata(-sâman); the Udgâtri's preliminary muttering (of the text of his chants) on that occasion is the Satarudriya; the 'shower of wealth' the Great Litany; and what takes place subsequent to (the singing of) the sâmans, and prior to the shower of wealth, that is the Hotri's preliminary muttering on that occasion; and what takes place after the shower of wealth is the Grihamedhas (house-sacrifices). Such are all the sacrifices: these he secures by (building) the fire-altar.
