That is a really interesting story. Is there evidence for any of it or do we have to take your word for it?
"Sometimes if you walk barefeet on the grass you can really feel a connection to the Earths energy"
Really now. I never have, but if there is such a thing, I'm sure it has been determined and measured before. Would you point us to such a study, if one exists?
"some people you instinctively feel drawn towards and some you just want to get away from - without knowing why"
That is more likely because we are evolved to perceive and interpret hundreds of clues about a person's state of mind from facial expressions, tics, body language etc. We can like someone or be wary of him without knowing why with no need for glowing yet invisible lights around him.
"There is not really a scientific explaination of Reiki and nor should there be - it is beyond science really."
Sorry but
. "Beyond science"? What does that even mean?
Are you saying there will never be any evidence found for these "energies" or Reiki's effectiveness because, uh, it's beyond science? But you know that story is the truth because... how, exactly?
