Because he completes the Hindu cosmic cycle and heralds in the return of creation, Shiva (Siva) is revered as the destroyer, preserver, and creator. He has a vertical third eye in the centre of his forehead and wears his hair in a chignon with curls. He is frequently represented with four limbs and a trident, as well as a string of beads, a symbol of his teaching. Rudraksha beads are the name of the beads, which refers to his first name. Shaivism is a Hindu religion that worships Shiva as their principal deity.
