Dattatreya
Dattatreya is usually depicted with three heads, symbolising Brahma, Vishnu, and Shiva; past, present, and future; and the three states of consciousness: waking, dreaming, and dreamless sleep. He is portrayed sitting in meditation with his shakti beneath the audumbara (wish-fulfilling) tree. In front of him is a fire pit, and around him are four dogs. These are sometimes said to symbolise the four Vedas.
