Dear QBaby,

Anything can be used for good or bad. To a murderer, a knife is an
instrument of death. To a surgeon, a knife is an instrument of life.
Ying and Yang.

I agree with the other respondents that QiGong & Tai Chi have only
benefited me, perhaps because I intended to use them for good. At the
same time, other Qi-based systems have been developed for less honorable
goals, and these are well-documented. Any system of thought can be
warped, if that is the user's intention.

Even in the proper practice of Qi, there may develop what I regard as less
ideal outcomes, for instance, a religious devotion to or dependence upon a
certain system. If someone gets to the point of fanatic instance that
this or that way is the only way, and you have to do it this way or that
way, and you have to do this for so many hours a day, facing a certain
direction, etc., etc ... well, I say, thank you, I'm glad you found a way
that works for you, but yours is only one of many ways.

Above all, love and peace.
