I've just started reading Waysun Liao's Tai Chi Classics, and I'm a bit sceptical/confused about his chapter on the history of the art. He claims the only authentic style is something he calls "Temple" style, as it alone properly focuses on the meditative/internal aspects. He implies that this is essentially the original style, based on a modified Shaolin Kung Fu. Meanwhile, he claims the "family styles", as he calls them (i.e. Chen, Yang etc.), which came from the original style, are now primarily externally focussed. By "externally", my understanding is that he doesn't mean exclusively martial, but that they are based on empty forms driven by external movement, rather than internal energy, unlike the Temple style. He also claims the Temple style was preserved by Taoists living in "the mountains", while the family styles were deliberately watered down, basically to stop undesirables getting their hands on the skills (his implication is also that the families only taught the real skills to people they trusted). This all sounds dodgy to me, and contradicts what I've read so far. I wondered what everyone here thought about this.
