Commentary
Hariharānanda Bhāratī’s Sanskrit commentary, translated
"Iti āyurjananam" and what follows have a plain meaning. [The rite is āyur-janana, the giving of long life; the secret name is used only after the sacred thread; the śaucha impurity of a birth does not begin until the cord is cut, so the rites for the gods and ancestors are done before.]
