Sandhyavandanam

Sandhyavandane (Sanskrit: संध्यावन्दन sandhyāvandana) is a mandatory religious ritual that needs to be performed by all twice-born people of Hinduism. Especially brahmins who are initiated into the sacred thread ceremony called as Upanayanam, and instructed in its execution by a Guru (a qualified spiritual teacher). Sandhyavandanam consists of excerpts from the Vedas that are to be performed thrice daily at morning (prātaḥsaṃdhyā), at noon (mādhyānika), and in the evening (sāyaṃsaṃdhyā).
