Shamans look at the spiritual form of illness which might manifest on an emotional or physical level. Most shamanic cultures around the world believe that illness is due to the loss of the soul.
It is believed that whenever we suffer an emotional or physical trauma a part of our soul flees the body in order to survive the experience. The definition of soul is our essence, life force, the part of our vitality that keeps us alive and thriving.
The types of trauma that could cause soul loss in our culture would be any kind of abuse sexual, physical, or emotional.
It has always been the role of the shaman to go into an altered state of consciousness and track down where the soul fled to in the alternate realities and return it to the body of the client.
