Kautilya's Arthashastra 1.17.26

1.17.26

prajātāyāḥ putrasaṃskāraṃ purohitaḥ kuryāt //

"This," says Kautilya, "is death in life; for no sooner is a royal family with a prince or princes given to dissipation attacked, than it perishes like a worm-eaten piece of wood. Hence when the queen attains the age favourable for procreation, priests shall offer to Indra and Brihaspati the requisite oblations. When she is big with a child, the king shall observe the instructions of midwifery with regard to gestation and delivery. After delivery, the priests shall perform the prescribed purificatory ceremonials. When the prince attains the necessary age, adepts shall train him under proper discipline."
