And if anything be spilt, let him pour water thereon--everything here being pervaded (or obtained) by water--for the obtainment of everything; with a verse to Vishnu and Varuna,--for whatsoever distress one undergoes here on earth, all that Varuna inflicts,--(Vâg. S. VIII, 59; Atharva-veda VII, 25, 1), 'They by whose vigour the spheres were propped up, who are in strength the strongest and mightiest; who sway with powers unresisted, to Vishnu and Varuna hath it gone at the morning prayer!' For Vishnu is the sacrifice, and it is that (sacrifice) of his which now undergoes distress; and Varuna is the inflicter: thus by both these deities--that whose (sacrifice) undergoes distress, and that which inflicts it--he heals (the joint of the sacrifice), by both he puts it together.
