there was a scene in LOCH when ZBT was asked about his mastery of 9yin and he replied that he had 'forgotten' it. when ZWJ learned taiji quan, in order to learn the essence but not not limiting form, he had to 'forget' the stances. so was ZBT saying in double talk that he already mastered it fully while trying to seem like he hadn't. who else had reached the level of forgetting martial arts stances. guo jing forgets every stance and takes forever to remember them when young. did he learn to forget them as he mastered his skills. thinking wasn't his strong point. his reactions seemed mostly trained battle instinct when fighting in ROCH. yang guo came to the conclusion of using his skills freely, no limitations, use what ever is convient, did he also reach the 'forgetting level after training in the south seas?
