What Jesus is urging, then, is that our lives and personalities are to be brought to completeness, to the end goal for which they are destined. This will necessarily involve recognition of the Shadow and the acceptance of this part of ourselves as an inevitable part of our totality. The solution to the shadow problem that Jesus suggest, then, involves the growth of psychological consciousness and spiritual maturity by the recognition of our dark side as well as of our light side; he does not call upon us to repress the Shadow and identify with a persona.
