IMHO, yes.
I doubt there are a lot of people on this forum that have the DVD’s, fewer that know Bruce’s system in enough depth to judge, fewer that have actually practiced San Ti seriously, and still fewer that are willing to answer such an open ended question.
I don’t have a lot of experience with San Ti. When I practice it, I stand for one hour on one side. It takes everything I’ve learned over the past 20 years to “survive” standing that long including the most advanced dissolving practices I know. In my experience it can be extraordinarily challenging to keep the body relaxed and open for an extended period of time. The San Ti posture makes everything significantly more difficult. The integration it develops is directly proportional to its degree of difficulty.
