The great music historian and jazz critic Nat Hentofff on John Coltrane: Coltrane, a man of almost unbelievable gentleness made human to us lesser mortals by his very occasional rages. Coltrane, an authentically spiritual man, but not innocent of carnal imperatives. Or perhaps more accurately, a man, in his last years, especially but not exclusively consumed by affairs of the spirit. That is, having constructed a personal world view (or view of the cosmos) on a residue of Christianity and an infusion of Eastern meditative practices and concerns, Coltrane became a theosophist of jazz. The music was a way of self-purgation so that he could learn more about himself to the end of making himself and his music part of the unity of all being. He truly believed this, and in this respect, as well as musically, he has been a powerful infuence on many musicians since. He considered music to be a healing art, an "uplifting" art.
