This program sounds pretty extreme, IMO. And almost 10K? Holy......

The victims were attending a five-day program called "Spiritual Warrior," hosted by self-help guru and inspirational speaker James Arthur Ray.
Ray, a frequent guest on TV talk shows, calls himself "a personal success strategist," and his Web site details a sampler of international spiritual philosophies that he has fused into his program.
The Angel Valley Spiritual Resort Web site says that Ray has held the workshop there since 2003. And Ray's Web site lists the cost for next year's program at "only $9,695 per person."
The program brochure promises that the participants will push themselves past their "self-imposed and conditioned borders" and "learn (and apply) the awesome power of 'integrity of action.'" It describes the sweat lodge as "a ceremonial sauna involving tight, enclosed spaces and intense temperatures."
Participants in the Ray program also could practice Holotropic Breathwork, a trancelike state brought on by breath control, and Vision Quest, a multi-day stay in the outdoors without food or water, according to the James Ray International literature.
