Each of the two trigrams represents the sun in the course of a day. The two together represent the repeated movement of the sun, the function of light with respect to time. The great man continues the work of nature in the human world. Through the clarity of his nature he causes the light to spread farther and farther and to penetrate the nature of man ever more deeply.



The lines
Nine at the beginning [yang at bottom] means:
The footprints run criss-cross.
If one is seriously intent, no blame.
It is early morning and work begins. The mind has been closed to the outside world in sleep; now its connections with the world begin again. The traces of one\'s impressions run criss-cross. Activity and haste prevail. It is important then to preserve inner composure and not to allow oneself to be swept along by the bustle of life. If one is serious and composed, he can acquire the clarity of mind needed for coming to terms with the innumerable impressions that pour in. It is precisely at the beginning that serious concentration is important, because the beginning holds the seed of all that is to follow.
Six in the second place means:
Yellow light. Supreme good fortune.
Midday has come; the sun shines with a yellow light. Yellow is the colour of measure and mean. Yellow light is therefore a symbol of the highest culture and art, whose consummate harmony consists in holding to the mean.
Nine in the third place means:
In the light of the setting sun,
Men either beat the pot and sing
Or loudly bewail the approach of old age.
Misfortune.
Here the end of the day has come. The light of the setting sun calls to mind the fact that life is transitory and conditional. Caught in this external bondage, men are usually robbed of their inner freedom as well. The sense of the transitoriness of life impels them to uninhibited revelry in order to enjoy life while it lasts, or else they yield to melancholy and spoil the precious time by lamenting the approach of old age. Both attitudes are wrong. To the superior man it makes no difference whether death comes early or late. He cultivates himself, awaits his allotted time, and in this way secures his fate.
