He then makes an 'under-layer' of butter (in the guhû), takes two cuttings from that pap, pours some butter thereon, re-anoints (replenishes with butter the parts of the sacrificial dish from which he has made) the two cuttings, and steps across (to the offering-place). Having stepped across and called for the Sraushat, he says, 'Pronounce the offering-prayer to the Maruts, the Householders!' and pours out the oblation, as soon as the Vashat has been uttered.
