To follow up on what LH and Two Bears have said, in my first post to this thread, I said:

some of us don't see "matter" and "spirit" as being separate at all.

...and Wolfgang gave us this:

Once you realise that Kirlian photographs of not living matter lead to the same observable phenomena, you quickly drop the interpretation of the effect as an energy field, because it makes no sense any longer.

I'd say this point from Wolfgang actually supports the idea of matter and spirit being the same thing, much more than it undermines it.
