Thanx again for the kind words! Maybe Tridaya is not that special or different from other known energy training techniques, but as you said chief108, it could be the small details which are important, and maybe there are some significant details in this method, which makes it work very fast.

I have also seen some chi gung forms (if I remember correct) that also emphazise heavily on breathing and also contraction/tensing or they were performing some kind of "hardening" of the muscles. For example in Tridaya, in one exercise - you breath energy into Tan Ti`en. Then hold the breath, tensing the muscle, in other words "hardening" the stomach as much as you can. Then slowly relax and breath out.

Are there Chi gung forms similar to that Or which focus especially on the "hardening", maybe combined with breathing If so, I think there will be a very good chance of succeeding with an egg test with such kind of training too, even though it`s not Tridaya. Are there some forms of chi gung which focus especially on such extreme controlled breathing (breath in/out for a spesific number of seconds, holding of the breath for a number of seconds etc).

And by the way, maybe we should just forget the word Tridaya, and instead just focus on the technique I understand the claims of Tridaya can provocate some people, and these claims are truly incredible. But if we for a minute forget all of these claims, and just focus on the technique. The breathing method, and the extreme hardening of the body during exercise. Where in the martial arts universe can we find similar techniques
