Using
            the body as a medium of communication, the expression
            of dance is perhaps the most intricate and developed,
            yet easily understood art form. Dance in India has
            seeped into several other realms like poetry,
            sculpture, architecture, literature, music and
            theatre. The earliest archaeological evidence is a
            beautiful statuette of a dancing girl, dated around
            6000 B.C. Bharatha's Natya Sastra (believed to be
            penned between second century B.C. and second century
            A.D.) is the earliest available treatise on
            dramaturgy. All forms of Indian classical dances owe
            allegiance to Natya Sastra, regarded as the fifth
            Veda. It is said that Brahma, the Creator, created
            Natya, taking literature from the Rig Veda, song from
            the Sama Veda, abhinaya or expression from the Yajur
            Veda and rasa or aesthetic experience from the
            Atharvana Veda. Temple panel, Orissa

            also contains deliberations on the different kind of
            postures, the mudras or hand formations and their
            meanings, the kind of emotions and their
            categorisation, not to mention the kind of attire,
            the stage, the ornaments and even the audience. All
            dance forms are thus structured around the nine rasas
            or emotions, hasya (happiness), krodha (anger),
            bhibasta (disgust), bhaya (fear), shoka (sorrow),
            viram (courage), karuna (compassion), adbhuta
            (wonder) and shanta (serenity). All dance forms
            follow the same hand gestures or hasta mudras for
            each of these rasas. The dances differ where the
            local genius has adapted it to local demands and
            needs. 
            Indian
            dance is a blend of nritta - the rhythmic elements,
            nritya - the combination of rhythm with expression
            and natya - the dramatic element. Nritta is the
            rhythmic movement of the body in dance, pure dance.
            It does not express any emotion. Nritya is usually
            expressed through the eyes, hands and facial
            movements. Nritya combined with nritta makes up the
            usual dance programmes. Nritya comprises abhinaya,
            depicting rasa (sentiment) and bhava (mood).To
            appreciate natya or dance drama, one has to
            understand and appreciate Indian legends. Most Indian
            dances take their themes from India's rich mythology
            and folk legends. Hindu gods and goddesses like
            Vishnu and Lakshmi, Rama and Sita, Krishna and Radha
            are all depicted in classical Indian dances. Each
            dance form also draws inspiration from stories
            depicting the life, ethics and beliefs of the Indian
            people. 
            The
            fascination for Indian dance all over the world is
            indicative of the deep-felt need to use the human
            body to express and celebrate the great universal
            truths. Indian dance does just that in a heightened,
            reverential form. Also, since dance is physical and
            visual, it illuminates India's culture in a direct
            manner, playing on the sensibilities of the onlooker.
            Thus, those who are attracted to India will find the
            idiom of dance the best introduction to India's rich
            ethos and traditions. 
            One
            of the most enduring symbols of India is the figure
            of Shiv Nataraj or the dancing Shiva. Shiva's cosmic
            dance is believed to encompass creation,
            preservation, and destruction and this idea has been
            embedded in Hindu thought and ritual since the dawn
            of civilisation. 
            In
            India, dance and music pervade all aspects of life
            and bring colour, joy and gaiety to a number of
            festivals and ceremonies. In fact, dance and music
            are tied inextricably to festivity of any kind.
