"Spirit in Health" explores ancient healing techniques as they migrate into our modern culture. Healers in ancient societies invoked spiritual force, asking spirits for help in the hunt, for wisdom, for healing in its many forms and for knowledge of plant and animal powers. Healers and shamans were also psychotherapists, using spirit-powers to treat physical and mental complaints. The Spirit is once again finding healing roles in our modern world. The placebo effect is ancient. So is visualization as a weapon against cancers. And many physical ills, heart attack and cancers among them, may involve psychological causes. Now, at a time when modern technology should guarantee an escape from all things primitive, some ancient ways are returning, offering alternative destinies. Ultimately, "Spirit in Health" finds us reaching with Animists' tools to heal the sick, and the biosphere of our planet as well.
