Psychedelics can be profoundly healing, but on the other hand they can blow holes in the aura leaving some open to entity possession. Much depends on one’s own state of mind, body and Spirit at the time, and the protection given by the shaman ministering the medicine. And many of these so-called shamans are clueless, jumping on the bandwagon of a growing interest in their use from the West. It is also very easy for the ego to take control of some experiences, creating a Messiah-like complex, in the same way that psychic experiences can be used either by the Spirit or the ego.
