Jewish customs stem from Kabbalists who discovered the system of leadership through which the Creator, the upper force, operates us. The blessings mean that I have revealed the upper force as good and benevolent, and therefore I bless it. The Creator created an evil inclination in us, the ego, and He “created a Torah spice for it,” a positive force that can balance the ego. We have to reach a state in which we say the blessings not simply as words from our mouth but in thought and desire. This happens as a result of the correction of the ego.
