Hi Ron,

> Does Zen meditation lead to the production of theta [brain] waves?
I haven't really studied this - I know there is much study of such
things. The most interesting is in our electro-magnetic field. It can
be easy to be fooled by 'psuedo' research in this area. I like the
idea that conciousness
involves the whole bodeis EM field. Dr Jon Joe McFadden is good on this.
With yoga/ meditation you aren't directly trying to achieve things
like this. You are creating optimal conditions for the systems that
'repair' us to operate. This requires intense inward study of
yourself - bringing the messages of your proprioception to
conciousness. Then you can see how you really operate (physically and
emotional) and start to stimulate those 'healing' systems even
more....
