And the Pratiprasthâtri walks round (on the south side) with (Vâg. S. VII, 18), 'Abounding in creatures, producing creatures'--for to this (libation) corresponds the food, and the creatures, the people, are the food: hence he says, 'Abounding in creatures, producing creatures,'--'encompass thou the sacrificer with growth of wealth!' By saying 'Encompass thou the sacrificer with growth of wealth!' he invokes a blessing on the sacrificer.
