Now some put off those garments, and make him put on again the garment of initiation. But let him not do this; for, the limbs being his natural vestments, they deprive him of his limbs, of his native bodily form. The garment of initiation belongs to Varuna. Let him put on one of those same garments: he (the priest) thereby causes him to be furnished with his limbs, his native bodily form. The garment of initiation belongs to Varuna: he thus saves him from the Varunic garment of initiation.
