Sandhyavandanam
Sandhyavandanam (Sanskrit: सन्ध्यावन्दनम्, romanized: sandhyāvandanam, lit. 'salutation to (Goddess) Twilight', or 'salutation during the twilight') is a mandatory religious ritual centring around the recitation of the Gayatri mantra, traditionally supposed to be performed three times a day by Dvija communities of Hindus, particularly those initiated through the sacred thread ceremony referred to as the Upanayanam and instructed in its execution by a Guru, in this case one qualified to teach Vedic ritual. Sandhyopasana is considered as a path to attain liberation (moksha).
