My caution in this article is therefore based on this personal path and the clinical practice that is mine and which is recognized by Amazonian healers. Reiki propulses its users in a completely unknown field of practitioners who hold no thread from Ariane in their hand. My caution is therefore, in a short way, in a few words: speed is dangerous, deceptive ease. In no case can one exempt from a slow and patient work on your own or think of making the economy of confrontation with its own inner darkness and the powers of evil. As it is currently developing, Reiki practice, based on ignorance of intermediate world structures and by offering short-circuit ancestral knowledge in this regard, is highly irresponsible and potentially dangerous.
