Trauma - healed by facing the pain
Feelings/emotions that gain expression do not hurt. What hurts is the blockage. Life is motion and as long as it is allowed to move it doesn't hurt. Whenever it is stopped the pain grows. Therefore the will of healing always means to deal with pain. The frozen life starts to flow again when the pain is allowed to brake through.
The technique of regression
To express emotions might offer relief but does not cause healing. It is crucial to experience all those emotions in the correct context. You are kind of time travelling back to the time and place where the crack has happened. That's the moment when a new course will be set for you.
Thus the blockage realeases, the view unveils, the diversity of the world and one's own possibilities increase and the heart disburdens. Compulsions, addictions, diseases disappear all by themself; serenity, insight, forgiveness, self-esteem arise. All this is not to be "learned" or "practiced", it happens of it's own volition as a result of disolving such blockages and healing the traumas.
