Maria Popova of Brain Pickings commemorates Oliver Sacks and references the moment during which music saved his life. 

Or, more accurately, I had forgotten my fear — partly seeing that it was no longer appropriate, partly that it had been absurd in the first place. I had no room now for this fear, or for any other fear, because I was filled to the brim with music. And even when it was not literally (audibly) music, there was the music of my muscle-orchestra playing — “the silent music of the body,” in Harvey’s lovely phrase. With this playing, the musicality of my motion, I myself became the music — “You are the music, while the music lasts.”
