Shiva, is one of the most mysterious Gods of the Hindu pantheon. His energy can be found in all things, yet his tranquil, yet fierce energy can seem out of reach for some. His images often depict him in a meditative state or in his most common form, the Nataraja or the one who dances within the circular fires that represent creation and dissolution.
He is by far one of the most ancient of the Hindu Gods, there are hints of him in the Vedas, and this form is often called “proto-Shiva.” In his current incarnation he is part of the Hindu Trinity that is comprised of the Gods Brahma and Vishnu.
Shiva’s name means "the auspicious one”. Shiva is the God of creation, destruction and regeneration. It is for this reason his mantras are so powerful, they are multipurpose and can serve the magician in any way he or she sees fit.

Although most deities that I work with are female, Shiva is the only exception. He has been my patron for decades, I even have a tattoo of his image on my back. He is very close to me.

Often Shiva is associated with unbridled sexuality, eccentricity and nirvanic states. He has all these within himself. He is no doubt a figure that would be interpreted in the west as the embodiment of all that is evil, sinful and dark. This reputation is not helped by the fact many of his followers are known to perform actions that are often shocking and even downright lewd. They do this not because they are degenerates, but because they are trying to prove a point. In many ways, Shiva is the God of the outcasts.

Shiva will challenge you in ways other Gods will not. He will force you to go deep into your nature. If you are not introspective, Shiva will and can be a nightmare for you. He will force you to break open.
His mantras are often recited when people need help. All problems you may have, be they physical, mental or spiritual he can help you.
