Reading edition
p. 38. l. 12. —twice-born Sages, know ye me. The three first castes are "twice-born." The first birth is from the natural mother; the second from the ligation of the zone; the third from the due performance of the sacrifice: such are the births of him who is usually called twice-born, according to the text of the Veda: among them his divine birth is that which is distinguished by the ligation of the zone and sacrificial cord, and in that birth the Gayatri is his mother, and the Acharya his father.
