11.1.18

tad yad ardharcaśo anvāha /

mensurate with the Ṛc; the first half verse is this world, the second yonder world; what is between the two half verses is the atmosphere here. In that he recites by half verses, verily thus he makes the sacrificer to prosper with these worlds; verily thus he places the sacrificer in these worlds.
