Our tradition teaches us that sound is God—Nada Brahma. That is, musical sound and the musical experience are steps to the realization of the self. We view music as a kind of spiritual discipline that raises one’s inner being to divine peacefulness and bliss. We are taught that one of the fundamental goals a Hindu works toward in his lifetime is a knowledge of the true meaning of the universe—its unchanging, eternal essence—and this is realized first by a complete knowledge of one’s self and one’s own nature. The highest aim of our music is to reveal the essence of the universe it reflects, and the ragas are among the means by which this essence can be apprehended. Thus, through music, one can reach God.
