I've read most of these texts before,I thought I made it clear in my post that I am interested in discussing specific practices as it is well known that it is through direct experience that understanding may occur.To reiterate,I have practiced taijiquan and qigong for 20 years,yoga and meditation for 30 years and Shaolin gong-fu for 10 years.My current sifu is Yan Lei who entered the Shaolin temple aged 14,he teaches Xi Sui Jing which involves seated meditation,a hand-form,lifting weights with the genitalia and then beating oneself from head to foot with your bamboo(or steel)equipment.This is known as Shaolin steel-jacket (or Iron-shirt).If any one has anything to say about these practices I would be interested,particularly regarding Xi Sui Jing,which seems quite extreme. ps: thanks for the link to the movie, "Samsara" which I very much enjoyed,Dan.
