History of Dharmashastra (Ancient and Mediaeval Religious and Civil Law in India) v2.c24.s1.157

v2.c24.s1.157

*Saṁdhyā*:—On the day of upanayana there is no morning *saṁdhyā*. Jaimini⁷³⁹ says 'as long as there is no imparting of the Gāyatrī there is no saṁdhyā.' So the student begins his saṁdhyā in the noon of the day of upanayana. As however on that day he knows no Vedic text except the Gāyatrī, his whole saṁdhyā worship consists of the Gāyatrī.
