Eastern mysticism?

The late Great Grandmaster Wu Tu Nan demonstrating tai chi push-hand sills at the age of 100!

I once read a comment on a video posted on YouTube showing an old Chinese master doing Tai Chi push-hands. It says 'Mystical nonsense!'
I found this rather a sweeping statement. One thing was for sure - the guy who made the remarks simply had no clue to what was being demonstrated in the video piece - the workings of internal power of Chi. This is actually quite typical, for any thing that comes from the Orient which puzzles the westerners are generally referred to as 'mysticism', a term which implies bewilderment to a western mind. The western mind is conditioned to comprehend things that can be subject to mathmatics and science. Anything beyond is considered either metaphysical, mystical or even supersticious. Such an attitude is epitomed in the concluding remark of Hume in his Enquiry, ''If we take in our hand any volume; of divinity or school metaphysics, for instance; let us ask, Does it contain any experimental reasoning concerning matter of fact or evidence? No. Commit it then to the flames; for it can contain nothing but sophistry and illusion.''
In my view it is this blind faith in reason and rationality that creates illusion, confusion and conflict. For the world we live in and the Universe itself cannot be subject to reason. Questions such as 'What is the purpose of life?', 'Why do we suffer?', 'Why are civilized people still killing each other? cannot be answered with scientific analysis or reason. I think the strong desire to find answers to the ultimate question of birth and death has resulted in the creation on the human part of the Divine, an all-powerful personal God who will lift us out of suffering at the end it all.
The East is actually more practical in its endeavour to find solutions to the ultimate enigma of life, death and suffering. In the tradition of Taoist internal alchemy which is viewed by outsiders as esoteric and mystical, a very progmatic and comprehensive training regime is laid out for aspirants to train his body and mind. This is called 'twin cultivation of psyche and vitality' (xin min shuang xiu) - the psyche being the mental and spiritual side of the work while vitality the energy work or to be more specific, the firing process of Chi. The need to refine and sublimate one's Chi is not a moral argument; it is purely practical. If one's Chi or energy doesn't get accumulated, purified, sublimated, it will just keep leaking out and diminishing through sexual activities and other mundane pursuits. However, if the Chi gets sublimated through firing process and accumulated through introversion of the mind, it will rise upward until bursting through the crown in the head to eventually connect with the Cosmic energy. Only then can the individual consciousness be transcendented and one becomes merged with the Totality, the ultimate Truth, or the Divine, whatever you prefer to call it (the name is not the thing, anyway). Such fusion can be directly experienced in this very life of each individual here on earth!  So in this sense Taoist alcehmy is nothing that mystical. In my view it is certainly more practical than holding on to the belief in resurrection when the Judgement Day comes.
