Shiva (/ˈʃɪvə/; Sanskrit: शिव, lit. 'The Auspicious One', IAST: Śiva [ɕɪʋɐ]), also known as Mahadeva (/məˈhɑː ˈdeɪvə/; Sanskrit: महादेव:, lit. 'The Great God', IAST: Mahādevaḥ, [mɐɦaːd̪eːʋɐh]) and Hara, is one of the principal deities of Hinduism. He is the Supreme Being in Shaivism, one of the major traditions within Hinduism.
In the Shaivite tradition, Shiva is the Supreme Lord who creates, protects and transforms the universe. In the goddess-oriented Shakta tradition, the Supreme Goddess (Devi) is regarded as the energy and creative power (Shakti) and the equal complementary partner of Shiva. Shiva is one of the five equivalent deities in Panchayatana puja of the Smarta tradition of Hinduism. Shiva is known as The Destroyer within the Trimurti, the Hindu trinity which also includes Brahma and Vishnu.
