Correspondence

Each of the lines corresponds to one other line. The bottom line of the lower trigram, line 1, corresponds to the bottom line of the upper trigram, line 4. Similarly, the middle line of the lower trigram, line 2, corresponds to the middle line of the upper trigram, line 5. The top line of the lower trigram, line 3, corresponds to the top line of the upper trigram, line 6.
When corresponding lines are the same, both divided or both undivided, they generally oppose each other as do the positive ends of two magnets facing each other: the force of one repels the force of the other. When corresponding lines are different, they are helpful to each other. For instance, when a strong ruler, who will be represented by an undivided line in the fifth place, has a compliant official, who will be represented by a divided line in the second place, there is no conflict, and the official carries out his ruler’s orders.
If the ruler is weak and the official strong, the ruler can still rely on his trustworthy official to carry out his orders. If the ruler is strong and the official is strong, the chances are that the official will be headstrong, argumentative, and insubordinate—not a good condition. If the ruler and the official are both weak, they will not be able to make progress. Remember that this is a general rule and can be overridden by a particular situation or condition of the kua. Such conditions or situations will be detailed in the kua.
