But what is most remarkable is that the mystics played such an important part in the development of Indian music. They used it for their meditation, as it was invented and taught by Mahadeva. Music is the most wonderful way to spiritual realization; there is no quicker and no surer way of attaining spiritual perfection than through music. The great Indian mystics such as Narada and Tumbara were singers; Krishna played the flute; and thus music in its tradition and practice has always been connected with mysticism. Musicians have always held to the principle that modern scientists have rediscovered: that the ear is incapable of fully enjoying two sounds played or sung together, and that is why they enriched the melody to such an extent for the purpose of their meditation.
