While in hexagram 28, Preponderance of the Great, the strong lines have the preponderance and are inside, enclosed between the two lines at the beginning and the end, here the weak lines have the preponderance and are likewise on the outside, while the strong lines are inside. It is precisely on this that the exceptional situation rests. If the strong lines are on the outside, we have hexagram 27, The Corners of the Mouth (Nourishment), and hexagram 61, Inner Truth, neither of which denotes an exceptional situation. When the strong lines have the preponderance inside, they must assert themselves. This creates struggle and exceptional situations in great matters. Here, by contrast, what is weak must of necessity take over the representation to the outside world. When one stands in a decisive place that by one's nature one is not really equal to, extraordinary caution is needed.
