History of Dharmashastra (Ancient and Mediaeval Religious and Civil Law in India) v2.c24.s1.54

v2.c24.s1.54

Later writers went on adding mantras and details. On the day prior to upanayana the Nāndīśrāddha was performed as said by Haradatta on Āp. gṛ. 10. 5. *Grahamakha* ( a sacrifice to the planets ) also may be performed the previous day or on any day within 7 or 10 days of the upanayana. Then before the actual upanayana, there is the worship of Gaṇapati and of Kuladevatās, puṇyāhavācana, the worship of Mātṛs and the consecration of the maṇḍapa-devatās. For the detailed modern procedure (prayoga) of upanayana, the S. R. M. (pp. 197-210), which in the main follows the briefer procedure in the gṛhya sūtras, may be consulted. Up to the act of making the boy dine with his mother it is the father who does everything; thereafter it is the ācārya who does the rest. The saṁkalpa of upanayana is given below⁶⁶⁹.
