Lots of my students began as skeptics. I’ve also had the good fortune of having most, if not all, of my students be critical thinkers. Finally, I haven’t yet met a student who could confidently say at the onset that they understood how Reiki or energy healing works. And while there are lots of great articles that attempt to explain the science behind how Reiki works (here’s a recent one), Reiki is an experiential process.
