One of the people to answer stated that unless you had been trained in healing energy it would seem to be nonsense.

Could someone who HAS been trained in this kind of energy please explain it to us? How does it work, how is it measured? What are its properties? What is the charge carrier - if any?
Hey Happy new year Rhianna. Rumors had it you were kidnapped by a white-slaver. I'm back at university again in a couple of weeks I need a good hobby to keep me busy. Cake done and ready, it'll improve over a couple of months.
Penny, really that does not have an explanation. Maybe I missed it but I searched the entire site for energy and there is no explanation about the energy. It asserts there IS energy, equally I could assert there is a pink unicorn living in my wardrobe

I hope this really isn't the best explanation that can be offered.
Well I must admit sometimes (only at weekends because I don't want to turn up on a client's site smelling like a boudoir) I like a few drops of white musk in the bath with a big glass of single malt to sip. Relaxing, but invisible energy?

No, I took a year off last year. Too much time on my hands recently though - I got library access back again - woohoo

Yes, starting my PhD
OK I extended expiration in the hope that SOMEONE might provide the answer. Otherwose the Jedi get it.
