Psychology investigates the person while still at the level of this world while the wisdom of Kabbalah investigates the soul. Psychology is limited since it distances itself from practical, physical life whereas the wisdom of Kabbalah teaches man how to control his impulses, expand his perception of reality, acquire good relationships, and attain a positive power that exists outside of him. Psychology works within the limitations of the evil inclination or the human ego. In order to break our egoistic perceptions and reveal the upper force in reality, we must aim for the benefit of the other.
