The snakes, too, are easily attracted by music, by the Indian flute, a piece of bamboo, or by the vina, if they hear it. But the vina players are serious people, and would rather charm human beings then the snakes. A special raga is used for charming snakes. The yogis and the Sufis in their meditations have always had music. Music is the greatest mystery in the world. The whole manifestation is made of vibrations, and vibrations contain all its secret. The vibrations of music free the soul, and take from a person all the heaviness which keeps him bound.
