Origin story
Brahma is the creator of the Trimurti, the trinity he shares with Vishnu the preserver and Shiva the dissolver. Puranic tradition describes him emerging from the golden egg Hiranyagarbha and shaping the worlds from the substance of creation, while his four heads recite the four Vedas and face the four directions.
He is shown red or golden, bearded, with four arms and the hamsa as his vehicle, and his consort is Saraswati, the goddess of learning. Direct shrines to Brahma are rare in Kerala; the Mithrananthapuram Trimurti Temple in Thiruvananthapuram keeps his shrine beside Vishnu and Shiva, one of the few places where the whole trinity is worshipped together.
