I'm struggling with this because I have done Reiki once, and I did feel the energy while doing it. I don't know whether to believe in the existence of energy that you can feel or not even though I can feel it because it appears to be a trick of the mind. Many people don't feel anything while others do, and it seems that people who are more sensitive in different ways are more likely to feel the energy. I wish there was a way to understand what happened. The things I felt can not be explained by mental anticipation because I was not told to expect them, so there is something going on and some validity to energy even if it is psychological, but I don't know what. To deny what I felt would be to deny my senses. It was just as real as anything that I have ever seen, heard, tasted, touched, etc... If I deny this aspect of sensory experience like people tell and expect me to, there is no reason why I should not deny other aspects as well. I don't want to go down that route. Does anyone have any idea or information?
