"Rāga", along with performance arts such as dance and music, has been historically integral to Hinduism, with some Hindus believing that music is itself a spiritual pursuit and a means to moksha (liberation). "Rāgas", in the Hindu tradition, are believed to have a natural existence. Artists don't invent them, they only discover them. Music appeals to human beings, according to Hinduism, because they are hidden harmonies of the ultimate creation. Some of its ancient texts such as the "Sama Veda" (~1000 BC) are structured entirely to melodic themes, it is sections of "Rigveda" set to music. The "rāgas" were envisioned by the Hindus as manifestation of the divine, a musical note treated as god or goddess with complex personality.
