He then takes (water) that flows off (the main current) with, 'Overflowing waters ye are, bestowers of kingship: bestow ye kingship on me, hail!--Overflowing waters ye are, bestowers of kingship: bestow ye kingship on N.N.!' With that (water) he sprinkles. Now that (flow of water), after separating itself from that (main current), comes to be that again; and so there is in his kingdom even one belonging to some other kingdom, and even that man from another kingdom he absorbs: thus he (the Adhvaryu) bestows abundance upon him (the king), and it is with abundance that he thus consecrates him. This is one kind of water: it is that he now brings.
