Among the holy triad of Hindu Gods, Shiva is the Destroyer. His power to obliterate the universe however, is not to be interpreted as nihilism. Creation flourishes when the law of dharma prevails and there is equilibrium between the positive and negative. When dark forces prevail, Shiva steps in and destroys everything, thus allowing for a new cycle of regeneration. Shiva's iconography is rich in symbolism. He wears a crescent moon, the symbol of intuitive powers upon his forehead. The sacred Ganges flowing from it is the eternal life-force. His hands are held in Mudra or stylized gestures indicating protection to devotees against fear and the giving of boons.
