If you visit my website
Metaphysical Institute and go to Links page there are many references and links to research on Life Energy Fields and if you are serious about factual Knowledge there are links to books on some of this research.
As to quoting one critical study I see on these forums, there are good and not so good doctors as in all professions including Energy Healers.
Also the knowledge base from 10 years ago is very old for this information age. Developments are happening daily with amazing advances. The difficulty is keeping up with them.
