Nritya

[1][2] It is sometimes subdivided into two forms: nritta or pure dance, where the expressionless movements of a dancer play out the rhythms and phrases of the music; and nritya or expressive dance, where the dancer includes facial expression and body language to portray mood and ideas with the rhythmic movements.

[3][4][5] These ideas appear in the Vedic literature of Hinduism such as the Aitareya Brahmana, and in early post-Vedic era Sanskrit texts such as the Natya Shastra, Panchatantra, Malvikagnimitra and Kathasaritsagara.

[2][6] Panini too mentions the terms Nritya and Nartaka respectively as dance and dancer, in his treatise on Sanskrit grammar.

It is the Purusha and Prakriti, expression of the evolution of the movement, a truly creative force that has come down to us from ages.

This embodiment of sound and rhythm, which creates poetry of spiritual expression is called dance or nritya.
