Brahma is the Lord of creation & is assisted in this process by his consort Saraswathi, who is the possessor of ultimate knowledge. Together, they thus introduce the soul into the cycle of life;
Brahma was born from the navel of Lord Vishnu at the end of one cycle to begin a fresh creation. He has four heads (originally five), representing the four vedas which are said to have sprung from his heads. His four heads are also said to represent the four yugas. He is bearded & his eyes are closed in meditation. He sits on a lotus & his vahana is the swan. In his four arms he holds the vedas, the kamandalam (water pot), suruva (sacrificial spoon) & a mala. He is a serene soul and is the provider of all sources of knowledge & wisdom.
There are no temples for Brahma (except the ones in Rajasthan & Orissa) as for Siva & Vishnu, for there has been no separate cult for Brahma as the Saiva or Vaishnava cult. According to mythology, he is supposed to have been cursed by Shiva (for his having uttered a lie & for his ego) that he would go without worship. Yet in all Siva & Vishnu temples, there is an image of Lord Brahma on the northern wall & he is one of the important Parivara devata (attendant deity).
