The physical will lasts for a fleeting second. The vital will very often plays the role of destruction. The mental will sooner or later finds satisfaction in contradicting itself. The psychic will, the soul's will, finds not only satisfaction but real fulfilment in identifying itself with God's Will. The psychic will gets its illumination and its message of perfection through unconditional surrender to the universal Will.
