An audience is just a mirror of what's happening on stage, and if what's happening on stage has love in it-real feeling and conviction and strength and purity-then we are truly reflecting them, because it is their own nature that is coming back. Everything is. The music is. For me, the only barriers in music are the barriers in the musician and in the equipment he has to use. If a musician has no barriers within himself, then there are no barriers within his music. His only battle is with the problems of expressing his true nature against the difficulties of the real world-the limits of his amplifiers and his guitar or his piano or whatever, the limits the outer world places upon the natural perfection of the spirit.
