Lord Shiva is most Powerful Hindu Diety. Shiva is the destroyer and one of the godheads in the Hindu Trinity. Known by many names - Mahadeva, Mahayogi, Pashupati, Nataraja, Bhairava, Vishwanath, Bhava, Bhole Nath - Lord Shiva is perhaps the most complex of Hindu deities.Shiva is usually worshipped in the aniconic form of lingam. He is described as an omniscient yogi, who lives an ascetic life on Mount Kailash with wife Parvati. Shiva has two sons Ganesha and Kartikeya. Shiva has many benevolent as well as fearsome forms. He is often depicted as immersed in deep meditation, with his wife and children or as the Cosmic Dancer. In fierce aspects, he is often depicted slaying demons. The Sanskrit word Shiva is an adjective meaning "pure and destroyer". As a proper name it means "The Auspicious One", used as a name for Rudra.
A Different Deity:
The actual image of Shiva is also distinct from other deities: his hair piled high on the top of his head, with a crescent tucked into it and the river Ganges tumbling from his hairs. Around his neck is a coiled serpent representing Kundalini or the spiritual energy within life. He holds a trident in his left hand in which is bound the 'damroo' (small leather drum). He sits on a tiger skin and on his right is a water pot. He wears the 'Rudraksha' beads and his whole body is smeared with ash.
The Destructive Force:
Shiva is believed to be at the core of the centrifugal force of the universe, because of his responsibility for death and destruction. Unlike the godhead Brahma, the Creator, or Vishnu, the Preserver, Shiva is the dissolving force in life. But Shiva dissolves in order to create, since death is the medium for rebirth into a new life. So the opposites of life and death and creation and destruction both reside in his character.
The Most Fascinating of Gods:
He is also often portrayed as the supreme ascetic with a passive and composed disposition. Sometimes he is depicted riding a bull called Nandi decked in garlands. Although a very complicated deity, Shiva is one of the most fascinating of Hindu gods.
