Ah, nice observation by Allan Lian. Amazing how some people that chose to travel higher roads can get so lost. On the other hand, perhaps, it is just too easy to get lost in a forest where the individual trees can call too much attention to themselves. In such cases, proper guides are advised.
If change can be so easily understood or seen, the holy sages need not write down its patterns and images in the Book of Changes (Yijing, the Yi) for posterity. Neither would the great Chinese sages, the wise and the learned, need to devote much time in studying this ancient Chinese classic, if it was not other than profound.
