pañcamyāṃ pratipakṣaṃ ca pūjayedbrahmavāsinīm
tathaiva taṇḍulaprasthaṃ ghṛtapātreṇa saṃyutam
kṣīraṃ dadyāddhiraṇyaṃ ca gāyatrī prīyatāmiti //

Gâyatrî with a Viṇâ (a kind of harp), a rosary of Akṣa, a Kamaṇḍulu and a book in each hand, should be worshipped with devotion, with white flowers and unhusked rice, &c. The pious devotee should, then in silence, take his meals, morning and evening, without speaking a word at the time. He should worship the Brahmavâsîni (Gâyatrî), on the fifth day of both the fortnights. He should also offer her a quantity of (Prastha) measure of rice, placed in a vessel and full of clarified butter and milk and gold, by invoking her in the following words:—“Gayatrî, be pleased with these.”—10-11.
