Quote from : Where the Heart Beats: John Cage, Zen Buddhism, and the Inner Life of Artists Book

So it is with the places preparing to teach us. It's only when the heart begins to beat wildly and without pattern—when it begins to realize its boundlessness—that its newly adamant pulse bangs on the walls of its cage and is bruised by its enclosure... To feel the heart pound is only the beginning. Next is to feel the hurt—the tearing of the psyche—the prelude of entry into the place one has always feared. One fears that place because of being drawn to it, loving it, and wanting to be taught by it. Without the need to be taught, who would feel the psyche rip? Without the bruise, who would know where the walls are?
