Oh boy!  Another pop-psychobabble get-em-rolling seminar like EST and all
the others.  :-)  Sarcasm aside, I have no opinion on their value.

Wow, I can't think of how many times I've needed to walk on hot coals!  :-)
There is a short article in the March issue of Science 85 on how fire-walking
works, prompted by this fad.  Essentially, there are a few physical reasons
why: coals have a very low specific heat and are very poor conductors of
heat, and moisture in the skin vaporizes which provides an insulating layer
of steam and dry skin which also conducts heat poorly.  It was pointed out
that a real test of mental powers would be to walk across aluminum heated
as hot.

I've never been to an EST seminar, but I read a book about it.
The climax of the seminar is when they tell you that you are a 
machine.  However, they say that you control the machine,
whereas I believe that God controls the machine.

Not at all.  The same boundary layer occurs.  The Scientific American
article some years back recommended heating the backs of shovels for this
experiment.  The author of the article had walked across 12 (I think)
shovels heated to 1500 degrees F.  Be careful if you try this though, the
boundary layer is not properly effective at LOWER temperatures (<1100
degrees).  At higher temperatures, the boundary layer is not effective
either, but you'll melt your shovels if you go too high anyway.
