'Of bees’ honey'--this is indeed honey;--'drink ye the Gharma (hot draught),'--that is to say, drink ye the liquor;'--'ye true ones,'--those (deities) are indeed true (vasu), for it is they that maintain (vâsaya) all this (universe);--'worship ye, vât!' thus this comes to be for him as if it were offered with the Vashat-call.
