A Native healer has at their disposal methods that utilize unseen forces of the natural world.  These tools include a specific ceremonial experience where the healer will journey on the spiritual planes of reality on behalf of those requesting assistance.  These are termed Soul Recovery journeys in some traditions.  The healer will momentarily leave this reality accompanied by their helpers or guides to seek out a spiritual cause or influence that contributes to the issue they seek assistance with.  The methods used to leave this reality vary and can involve drumming, chanting, meditation, prayer or other sacred experiences.
