(In the rite) the greatest number of libations are made, the greatest number of Çastras recited; verily in the middle of the sacrifice they tie a knot not to slip.

If they were not to descend to this world [3], the sacrificers would either go mad or perish. In that the Prsthas are reversed they descend to this world with them; verily also they find support in this world, for sanity. Indra was unsettled. He ran up to Prajapati; he gave him this (rite) of twenty-one nights; he grasped it, and sacrificed with it. Then indeed he became settled.

So many are the worlds of the gods; verily in them in order they find support. Yonder sun did not shine. He ran up to Prajapati; he gave him this (rite) of twenty-one nights; he grasped it, and sacrificed with it. Then in deed did he shine. Those, who knowing thus perform (the rite) of twenty one nights, shine also.
