| Lower Trigram: | Li, Clinging Brightness, Fire | |
| Governing Ruler: | Nine in the fifth place | |
The Image
Fire in the midst of a lake: the image of Ko. The superior man, in accordance with this, regulates his astronomical calculations, and makes clear the seasons and times.
Miscellaneous Signs
Ting takes what's new; the old is left by Ko.
The Judgement
What takes place as indicated by Ko, is believed in only after it has been accomplished. There will be great progress and success. Advantage will come from being firm and correct. In that case occasion for repentance will disappear.
Commentary
In Ko we see water and fire extinguishing each other; we see also two daughters dwelling together, but with their minds directed to different objects: on account of these things, it is called the hexagram of revolution.
'It is believed in only after it has been accomplished': when the revolution has taken place, faith is accorded to it. We have cultivated intelligence as the basis of joyful satisfaction, suggesting 'great progress and success' coming from what is correct. When change thus takes place in the proper way, 'occasion for repentance disappears'. Heaven and earth undergo their changes, and the four seasons complete their functions. Thang changed the appointment of the line of Hsia to the throne, and Wu that of the line of Shang, in accordance with the will of heaven and in response to the wishes of men. Great indeed is what takes place in a time of Revolution.
