Shiva is Nataraja, the cosmic dancer who is the creator, preserver, and destroyer of the universe and symbolizes the conception of the never-ending cycle of time. Shiva dances in a flaming halo, in his upper right hand the damaru ~ that made the first sounds of creation. Upper left hand holds agni (the fire that destroyS the universe).Thus a balance between creation and destruction. The lower right hand is in abhaya ~ protection mudra. The small figure being trampled by the right foot represents apasmara purusha ~ ego. Shiva's front left hand is pointed to his left foot, absolving the sins.

Calm yet fierce, the long tresses of Shiva embody passion and frantic energy splaying out to the cosmos , yielding and harmonizing the tranquil energies of life.
Shiva is known by many names like, Shankar the Giver of Joy; Shambhu, the Abode of Joy. As Maheshwar, he is the Divine Lord, the source of knowledge. In him are co-ordinated the three energies from which knowledge flows, the power of understanding(Jnana), the will(Iccha) and the action(Kriya). Shiva is Mahakala, it means not only the God of Death but also the God of Time. Before anything could come to exist, time has to be present. In fact time is the first condition for the existence of the world for it is prior to space.
Shiva is the dissolving force in life. 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. Nataraja or Nataraj, the dancing form of Lord Shiva means the King of Dancers and symbolizes a marvelously unified and dynamic creation involving the cosmos ,expressing the rhythm and harmony of life.
Shiva is the creator of dance and of the first 16 rhythmic syllables ever uttered, from which the Sanskrit language was born. His dance of anger is called the Roudra Tandava and his dance of joy, the Ananda Tandava. This cosmic dance of Shiva is called 'Anandatandava,' meaning the Dance of Bliss, and symbolizes the cosmic cycles of creation and destruction, as well as the daily rhythm of birth and death. The dance is a pictorial allegory of the five principle manifestations of eternal energy — creation, destruction, preservation, salvation, and illusion. According to Coomerswamy, the dance of Shiva also represents his five activities: 'Shrishti' (creation, evolution); 'Sthiti' (preservation, support); 'Samhara' (destruction, evolution); 'Tirobhava' (illusion); and 'Anugraha' (release, emancipation, grace).
Natraja is the Lord Of Dance and brings in the energy of creation so your dance studio or exercise room is the perfect place for him.
