Nataraja or Nataraj ([nɐtɐˈrɑdʒɐ], The Lord (or King) of Dance; Tamil: கூத்தன் (Kooththan)) is a depiction of the Hindu god Shiva as the cosmic dancer who performs his divine dance to destroy a weary universe and make preparations for god Brahma to start the process of creation
. Nataraja is most often depicted through a statue. The dance of Shiva in Tillai, the traditional name for Chidambaram, forms the motif for all the depictions of Shiva as Nataraja. He is also known as "Sabesan" which splits as "Sabayil aadum eesan" in Tamil which means "The Lord who dances on the dais".The form is present in most Shiva temples in South India, and is the main deity in the famous temple at Chidambaram.
The sculpture is usually made in bronze, with Shiva dancing in an aureole of flames, lifting his left leg (and in rare cases, the right leg) and balancing over a demon or dwarf (Apasmara) who symbolizes ignorance. It is a well known sculptural symbol in India and popularly used as a symbol of Indian culture.
The two most common forms of Shiva's dance are the Lasya (the gentle form of dance), associated with the creation of the world, and the Tandava (the violent and dangerous dance), associated with the destruction of weary worldviews - weary perspectives & lifestyles
. In essence, the Lasya and the Tandava are just two aspects of Shiva's nature; for he destroys in order to create, tearing down to build again.
