Since the Spirit healer village gets so many visitors from around the world, they capitalized on this and assign some of the disciples to entertain the visitors by doing live demonstration of the healing process. No actual spirit healing is done of course, since its just a demonstration to educate the visitors about the process. They would randomly pick a volunteer among the visitors to demonstrate a spirit healing with them. They would explain what goes on in every step of the process. Its all very culturally enriching stuff.
They've been receiving a rise of visitors and tourists ever since they start doing this live demonstration some time ago. It's great that many people are interested in their culture.
