2Savitr he sees. Having offered to Savitr, he offers to Aditi; Aditi indeed is this (earth); verily taking his stand on it he sees. Having offered to Aditi, he repeats the verse to the Maruts. The Maruts are the subjects of the gods. As the subjects of the gods are in harmony, so he brings the human subjects into harmony.' In that he repeats the verse to the Maruts, it is to bring subjects into harmony. The theologians say, 'The opening oblation should be performed with a fore-offering, but without an after-offering; the concluding oblation should be performed with all after-offering [3], but without a fore-offering.' These are the fore-offerings, and these the after-offerings, and this is the course of the sacrifice. This is not to be followed. The fore-offerings are the self; the after-offerings the offspring. If he were to omit the fore-offerings, he would omit the self; if he were to omits the after-offerings, he would omit offspring. In so far as the whole of the sacrifice is not performed, in so far does the sacrifice come to ruin, and the sacrificer comes to ruin along with the sacrifice [4]. Verily the opening oblation should be performed with both fore- and after-offerings, and the concluding oblation should be performed both with fore- and after offerings. He does not omit the self, nor offspring; the sacrifice does not come to ruin, nor the sacrificer. He offers the concluding oblation in the scrapings of the opening oblation; this is the course of the sacrifice. Now if he were to make the Yajya verses of the opening libation the Yajya verses of the concluding libation, he would mount to the other world away from this, and would be liable to die. The Puronuvakya verses of the opening libation should be made the Yajya verses of the concluding libation; verily he finds support in this world.
