People unconsciously fear pain because they do not understand that pain actually is healing, itself. All pain is growth. Furthermore, all pain experienced is pain which is leaving the body. There is no pain ever being introduced into the body. In other words, pain is one way people experience separation.
Human beings molt, just like crabs and snakes.
But so does our whole being. The one aspect of molting which humans deny, avoid, and resist the most is the molting of consciousness. Paradoxically, this is the most important part of the healing process because it affects all others and is the very vehicle for endearing one into the heart of God and for realizing one's own divinity. God did not create pain and suffering. It is not growth but resistance to growth which causes pain.
