Khien represents what is great and originating, penetrating, advantageous, correct and firm.
Explanation of the separate lines by the duke of Kau.
1. In the first or lowest nine, we see its subject as the dragon lying hid in the deep. It is not the time for active doing.
2. In the second nine, we see its subject as the dragon appearing in the field. It will be advantageous to meet with the great man.
3. In the third nine, we see its subject as the superior man active and vigilant all the day, and in the evening still careful and apprehensive. The position is dangerous, but there will be no mistake.
4. In the fourth nine, we see its subject as the dragon looking as if he were leaping up, but still in the deep. There will be no mistake.
5. In the fifth nine, we see its subject as the dragon on the wing in the sky. It will be advantageous to meet with the great man.
6. In the sixth or topmost nine, we see its subject as the dragon exceeding the proper limits. There will be occasion for repentance.
The lines of this hexagram are all strong and undivided, as appears from the use of the number nine. If the host of dragons thus appearing were to divest themselves of their heads, there would be good fortune.
