I Ching Hexagram 18: 蠱 “Correcting” – Ku

What Is Hexagram 18: “Correcting” ?

Ku is the Chinese name of the I Ching Hexagram 18. With inner and outer trigrams forming mountain over wind, this Hexagram is called ‘correction’ or alternatively named ‘restoration’ or ‘work on what has been decayed’.

Hexagram 18 symbolizes a time when progress has come to a halt because previous situations and problems have not been properly dealt with. It is hard to finish a progress when parts are missing or others parts are damaged.

In order to find peace in the universe, all the aspects of life must be balanced and not tarnished. It is very easy to dismiss a problem when it arises without properly dealing with the situation. No one likes to deal with unpleasant situations and it’s easy to run from the problem instead of fixing it.

Interpretation & Meaning of Hexagram 18:

Accurate IChing Forecasts


Hexagram 18 represents a time to focus on our life and see what areas could be fixed in order to progress. This could relate to disagreements in the work area that are keeping projects from being complete or negative feelings between partners that needs to be cleared up in order to continue the relationship.

One of the tricks for forgiving others is to realize that the pain or anger you have been feeling towards another person may not be the same feelings that person currently has. The pain and anger we hold inside is only affecting us and not that other person. It is likely that the focus of our rage is oblivious to how we feel.

When we come to terms with this realization, we can then take action to correct the painful feelings. Perhaps letting the person know what they have done to offend us will often spark a change in that person. The truth of the matter could be that the person had no idea of the repercussions of their actions.

I Ching Hexagram 18 – Personal Goals:

Harboring a grudge is like feeding water to a plant that is laced with poison. The plant may not die at first, but over time, the poison will keep the plant from reaching its full potential. By being open and honest to those who have hurt us, we can then create the change that is necessary to move on. Not dealing with problems as they arise will prevent everyone from progressing down the life path.

I Ching Hexagram 18 – Love:

It is very easy to hold a grudge against someone for a very long time. These feelings often fester inside of us and last for years. Soon we have forgotten the reason why the person has offended us but can still remember the feeling of being hurt. Eventually this displeasing feeling will catch up with us and we will have to face them.

It is very hard to forgive someone after long periods of time, so it is important to an overall being of a person to forgive often and in a fast manner in order to prevent long lasting feelings of pain.

I Ching Hexagram 18 – Career & Business:

Working well with others can often be difficult when the team members have different personalities. There are different forms of working that everyone prefers and it can sometimes be hard to settle on one method in a group. There is nothing wrong with disagreeing with the member of the group in order to find a better solution.

But when disagreeing turns into arguing and harboring harsh feelings against other people, then the progress in that plan has stopped. It is impossible to work with someone you can’t get along with and still be successful. If this type of problem has been a continuous phase at work, fix it now or it will be difficult to find peace in the work place.


Has supreme success.
It furthers one to cross the great water.
Before the starting point, three days.
After the starting point, three days.


The wind blows low on the mountain:
The image of DECAY.
Thus the superior man stirs up the people
And strengthens their spirit.


Hexagram 18 is a symbol that heads a warning against holding anger towards someone or something. Eventually all previous issues will pop up later in life and hold us back from being successful.

Being honest and open with ourselves and those that have offended us will often put into place the necessary change needed to progress. Waiting to heal old wounds will only cause a spiritual infection that will take serious surgery to repair.
