Psychotherapy is what God has been secretly doing for centuries by other names; that is, he searches through our personal history and heals what needs to be healed - the wounds of childhood or our own self-inflicted wounds.
Over time we are able to undermine habitual modes of thinking formed by our self-made self in early childhood, which tries to squeeze happiness from the gratification of our desires for the symbols in our culture of survival and security, power and control, and affection and esteem.
