Chiah (Hebrew ChIH, “life”) in Kabbalistic lore is the second highest aspect of the human soul corresponding to the second Sephirah Chokmah. Chiah is the essential energy or dynamism of the eternal aspect of the self, the neshamah. In many current magical traditions it is identified with the true will. A.G.H.
