"I invoke the sons of Brahman." Having thus invoked them, having cleansed [the area] with the three [verses] beginning with "You waters indeed are soothing," the four [verses] beginning with "Golden of color, pure, purifying," and with the section beginning with "The clarifying [Soma], generator of heaven," and having worshipped with fragrant unguents, flowers, incense, and lamps saying, "Homage to such-a-one, homage to such-a-one," he should offer a ball of rice mixed with milk rice in a clockwise manner saying, "Svāhā to such-a-one, svāhā to such-a-one."
