Condition

The bottom line indicates the onset of the condition depicted in the kua. It has just barely begun to manifest itself.
Line 2 shows the condition beginning to grow stronger, but because of the favorableness of the line in the middle of the lower trigram, the condition is usually under control.
Line 3 is at the top of the lower trigram, so the condition has grown stronger and is usually unstable because line 3 is about to leave the lower trigram for the upper, which is nearly always somewhat dangerous.
Line 4 shows the condition to be approaching its maximum potential; therefore, depending on whether the condition bodes good or evil, one must be cautious. Additional caution is required because line 4 is next to line 5, which is actually the ruler. Being close to a ruler can be very good, but it can also be very dangerous. If the situation warrants it, the kua will state which condition prevails.
Line 5 shows the condition having reached its maximum potential. Any movement beyond that point will cause the condition to exceed its maximum potential and turn it toward its opposite: fullness to emptiness, increase to decrease, abundance to want.
The top line shows the condition depicted in the kua having exceeded its maximum potential and consequently turning toward its opposite condition.
