If everything is spirit then there is no such thing as spirit and the very concept wouldn't exist.

We only know what "spirit" means because we have "matter" to differentiate it from.

As for Kirlian photography, who knows what the hell that is? One reason I loathe discussion about Kirlian photography is that instantly we have to start wading through every self-professed guru's crap about spirit and matter when nobody knows WHAT Kirlian photography is photographing, if anything.

We'll never know what spirit or matter are since they are only our mental constructs to deal with something we do not understand. They are only labels and are utterly useless.

The value of proof is that it tells one if something is useless or not. Without proof, I don't believe. To believe without proof is worse than useless--it is dangerous and highly irresponsible behavior for anyone who regards themselves as intelligent. Believing without proof and even disdaining proof is something I expect from George W. Bush and you can see where it has gotten us.
