Zhouyi BenyiLine statement
In a time of excess, dwelling in yielding with firmness is exceeding in reverence; this is the way to be free from blame. 'Not exceeding, meeting it' means not exceeding in firmness, but hitting upon what is fitting.
If one goes forward, one exceeds; hence there is peril and one must be cautious. The nature of yang is unyielding and firm; hence it is further admonished: 'Do not use perpetual constancy'—meaning one should adapt to the timeliness of the moment and not cling obstinately.
Some say: if 'not exceeding, meeting it' is explained according to the example of Six in the Second Place, it should be explained this way; if according to Nine in the Third Place, then 'exceeding and meeting' should be understood like 'exceeding in precaution.'
It is not yet clear which is right; this should be left open for the discerning.
