What is Shamanic Healing?
In Shamanic terms there are three classic reasons why we become ill: Soul loss, Power loss and Intrusions (energy we have taken on that in unhelpful). Though there are also Ancestral/Karmic and Past life reasons as well as Possession (considered an intrusion), basically, something needs to be removed or something needs to be returned to the person.
Often after receiving shamanic healing, which works on the soul/spirit level of our being, other healing work can then be more successful. This is because the root cause has been treated, which then opens the way for the physical work to be carried out successfully. For example, someone can be in therapy for years, unable to get past a certain block. This may be because of soul loss and once the soul essence has been returned by shamanic means, the block can then be moved beyond because the part that was needed is back home, the person is more fully present.
