In the ancient texts of Hinduism, the term for the technical mode part of "rāga" was "Jati". Later, "Jati" evolved to mean quantitative class of scales, while "rāga" evolved to become a more sophisticated concept that included the experience of the audience. A figurative sense of the word as 'passion, love, desire, delight' is also found in the "Mahabharata". The specialized sense of 'loveliness, beauty,' especially of voice or song, emerges in classical Sanskrit, used by Kalidasa and in the "Panchatantra".
