Preview of English translation:

1. Now at the time when he there proceeds with the guest-meal, he who intends to perform the Pravargya, prior to the Upasads, spreads Kusha grass with its tops directed towards the east, in front of the Garhapatya, and places the vessels thereon in pairs,—the Upayamani (tray) and the Mahavira (pot), the pair of lifting-sticks, the two milking-bowls, the two Rauhina-plates, the two offering spoons for the Rauhina (cakes), and whatever other (implement) there is,—these make ten, for the Viraj consists of ten syllables, and the sacrifice is Viraj: he thus makes this to be equal to the Viraj, the sacrifice. And as to their being in pairs,—a pair means strength, for when two take hold of each other they exert strength; and a pair (couple) means a productive union: with a productive union he thus supplies and completes it.
