Exceptional modesty and conscientiousness are sure to be rewarded with success; however, if a man is not to throw himself away, it is important that they should not become empty form and subservience but be combined always with a correct dignity in personal behavior. We must understand the demands of the time in order to find the necessary offset for its deficiencies and damages. In any event we must not count on great success, since the requisite strength is lacking. In this lies the importance of the message that one should not strive after lofty things but hold to lowly things. The structure of the hexagram gives rise to the idea that this message is brought by a bird. In Ta Kuo, Preponderance of the Great (hexagram 28), the four strong, heavy lines within, supported only by two weak lines without, give the image of a sagging ridgepole. Here the supporting weak lines are both outside and preponderant; this gives the image of a soaring bird. But a bird should not try to surpass itself and fly into the sun; it should descend to the earth, where its nest is. In this way it gives the message conveyed by the hexagram.
