Having cut out with a kindling-stick some of the butter, he offers sitting a libation, with (Vâg;. S. XII, 4,), 'To Visvakarman, hail!' Then stepping near he puts the kindling-stick on the fire, with (Vâg. S. XII, 44), 'Again the Âdityas, the Rudras, the Vasus may kindle thee, again the Brahmans with sacrifices, O bringer of good things!'--that is, 'May those deities again kindle thee!'--'With ghee make thou grow thy body, let the wishes of the Sacrificer be true!'--that is, 'With ghee indeed make thou grow thy body, and for whatever wishes the Sacrificer makes up a fire, may they all come true!'
