Ah, yes, Reiki – another form of woo BS, attracting the most gullible and illiterate.
“Reiki is therefore a form of vitalism – the pre-scientific belief that some spiritual energy animates the living, and is what separates living things from non-living things. The notion of vitalism was always an intellectual place-holder, responsible for whatever aspects of biology were not currently understood. But as science progressed, eventually we figured out all of the basic functions of life and there was simply nothing left for the vital force to do. It therefore faded from scientific thinking. We can add to that the fact that no one has been able to provide positive evidence for the existence of a vital force – it remains entirely unknown to science.”
