Here the climax of the darkening is reached. The dark power at first held so high a place the it could wound all who were on the side of the
good and of the light. But in the end it perishes of its own darkness, for evil must itself fall at the very moment when it has wholly overcome
the good, and thus consumed the energy to which it owed its direction.

The line at the top represents the evil ruler -- the tyrant Chou Hsin.

He climbed up to heaven in holding a position in which he might have been able to enlighten all the people of the realm.
Instead, however, he made it his business to injure men, and thus transgressed the rule hat binds one who governs;
as a result, he prepared his own downfall, his plunge into the depths of the earth.
That which veils the sun most heavily is also the first to be unmasked in its sinister character when the sun reappears.

It is said that when Chou Hsin, when he saw that he had been defeated by King Wu,
ended his life by throwing himself back into his burning palace.
His body was then riddled with arrows in a symbol of closure.
Among the Chinese characters defining this hexagram is one representing an arrow.

Indeed, another name for the hexagram means something closer to "shooting down the excess suns".
It relates back to a legend of ten suns that were burning up the earth,
and of an archer who saved the world by shooting down nine of them.
