Om Namah Shivaya means "I bow to Shiva", a Hindu mantra, commonly used during meditation. It is well-known as the great redeeming mantra, also known as the five-syllable mantra.
Shiva is the inner Self, the supreme reality. It is the name given to consciousness that resides in all. Shiva is the name of your self - your true identity.
According to Hindu traditions there are three deities who run this creation: The Vishnu - who preserves the Universe, the Brahma - who creates the universe, and the Shiva- who in the end destroys the universe. Among the three Gods, Shiva, although considered as destroyer, also symbolize the inner self which remains intact even after everything ends.
