Re: what does religion say about ki?
I do know THIS: a shodan in my class has a master degree in theology and is a card carrying christian like few I've ever seen... and HE has no problem with the term "Ki" and is able to grant that various people have varied opinions on it.
Find out what Ki is to YOU. So long as YOU understand it, can use it, work with and around and through it... what does it matter what other people think?
Be true to yourself... To thine own self, be true.
