Shiva (also spelled Śiva) is a Hindu god. The Hindu Shiva once saved the world by consuming poison, giving him blue skin around the area of the neck and throat. Shiva is a male god, but can merge with his consort Parvati to become Ardhanari, an androgynous Hindu god of duality. Shiva is the god of destruction along with Vishnu, who is the god of preservation, and Brahma, the god of creation. Together they are the three principle deities of the Trimurti (Hindu Triad). It is believed he periodically destroys the world, then recreates it.
