the trigram above - TUI - the Joyous, Lake
the trigram below - K’AN - the Abysmal, Water
The lake is above, water below; the lake is empty, dried up (literally "exhausted"). Exhaustion is expressed in yet another way: at the top, a dark line is holding down two light lines; below, a light line is hemmed in between two dark ones. the upper trigram belongs to the principle of darkness, the lower to the principle of light. Thus everywhere superior men are oppressed and held in restraint by inferior men.
Six at the beginning means:
One sits oppressed under a bare tree
And strays into a gloomy valley.
for three years one sees nothing.
When adversity befalls a man, it is important above all things for him to be strong and to overcome the trouble inwardly. If he is weak, the trouble overwhelms him. Instead of proceeding on his way, he remains sitting under a bare tree and falls even more deeply into gloom and melancholy. This makes the situation only more and more hopeless. Such an attitude comes from an inner delusion that he must by all means overcome.
Six in the third place means:
A man permits himself to be oppressed by stone,
And leans on thorns and thistles.
He enters his house and does not see his wife.
Misfortune.
This shows a man who is restless and indecisive in times of adversity. At first he wants to push ahead, then he encounters obstructions that, it is true, mean oppression only when recklessly dealt with. He butts his head against a wall and in consequence feels himself oppressed by the wall. Then he leans on things that have in themselves no stability and that are merely a hazard for him who leans on them. Thereupon he turns back irresolutely and retires into his house, only to find, as a fresh disappointment, that his wife is not there. Confucius says about this line:
If a man permits himself to be oppressed by something that ought not to oppress him, his name will certainly be disgraced. If he leans on things upon which one cannot lean, his life will certainly be endangered. For him who is in disgrace and danger, the hour of death draws near; how can he then still see his wife?
