There are different types of minds. Different types of meditation techniques
exist for different minds.

This is a meditation technique for someone feeling resentment for long period
of time, mood swings, hatred, anger etc.

Meditation is medicinal. It is medicine.

Encounter this technique with a fresh mind- with alertness , but not with
argumentation. Do not create fallacy that an argumentative mind is an alert
mind. It is not, because the moment you move into arguments you have lost
the awareness, you have lost the alertness.

When a mood against someone or for someone arises, do not place it on the person in question, but remain centered.

For this technique, remember that you are the source of everything that you go on projecting onto others. And whenever there is a mood against or for, immediately move within and go to the source from where this hate is coming. Remain centered there, do not move to the object. Move to the source. Someone has given you a chance to be aware of your own anger- Thank him immediately and forget him. Close your eyes, move within. You will find the source there because the anger is coming from your source.

When you feel hate, do not go to the object. Go to the point from where the hate is coming. Go not to the person to whom it is going, but to the center from where it is coming. Move to the center, go within. Use your hate or love or anger or anything as a journey toward your inner center, to the source. Move to the source and remain centered there.

Try it! This is a very , very scientific, Psychological technique.

There is one zen insight about this. One of the greatest of Zen masters, Lin chi, used to say, “while i was young i was very fascinated by boating. I had one small boat, and I would go on to the lake alone. For hours together I would remain there.

“Once it happened that with closed eyes I was in my boat meditating on the beautiful night. One empty boat came floating downstream and struck my boat. My eyes were closed, so i thought, Someone is here with his boat, and he has struck my boat. “ Anger arose. I opened my eyes and i was just going to say something to that man in anger, then i realized that the boat was empty. Then there was no way to move. To whom could i express the anger? The boat was empty. It was just floating downstream, and it had come and struck my boat. So there was nothing to do. There was no  possibility to project the anger on an empty boat.”

So Lin Chi said, “I closed my eyes. The anger was there, but finding no way out, I closed my eyes and just floated backward with the anger. And that empty boat became my realization. I came to a point within myself in that silent night. That empty boat was my master. And now if someone comes and insults me, I laugh and I say – “This boat is also empty”. And i close my eyes and i go within.

Use this technique. It may work miracles for you.

If you feel any affinity with it, play with it for three days. If you feel that it fits, that something clicks in you, continue it for three months.
