“You feel an extra spirit – arousing you, flowing over your entire body, bringing pleasure. It seems as if fine balsam oil has been poured over you from your head to your feet – once, maybe more. You are overjoyed, in delight and trembling; the soul in delight, the body in trembling. Like a rider racing a horse: the rider is joyful and exuberant, while underneath, the horse quivers.”

– The Kabbalah.
