From outside the Vedi (he takes it),--for the Vedi is this (earth), and the wind which is on this (earth) is already contained in this (fire-altar): he now puts into it the wind which is beyond this (earth).
4 By his two hollow hands (he takes it), for only in this way is the catching of that (wind brought about). With the Svâhâ-call (he offers), for he offers just under the shafts (of the chariot),--this chariot is yonder sun: he thus places the wind on this side of the sun, and hence that one blows on this side thereof.
