How would you characterize pentecostalism or charimatic Christianity in this context--animistic expressions of folk religion. The pentecostal experience doesn't seek out a host of spirit guides, but it does seek out an infilling of "the" Spirit, with all the attendant signs such as speaking in tongues, trance states, prophesy, visions, etc.
The more extreme forms of pentecostalism get pretty far out there with snake handling and drinking poison. If you've ever watched this ritual, from external appearances it isn't all that different than snake handling rituals among Hindus & Buddhists or fire dancing (walking on coals), which is practised in a range of animist groups.
Since there is such a natural attraction for humans to gravitate to animistic expressions of religion, isn't the real issue one of learning to discern spirits? Maybe the more prudent course of action is simply not to mess around with trance states that open a person up to all sorts of alternative realities?
