The Zen Circle

What is Zen? Zen is understanding myself. What am I? I explain Zen by means of a circle.
We begin from 0° to 90°. This is the area of thinking and attachment. Thinking is desire, desire is suffering.
Past 90° is the area of the Consciousness or Karma I. Below 90° there is attachment to name and form. Here there is attachment to thinking. All things have name and form, but their names and forms come from emptiness and will return to emptiness. This is still thinking.
At 180° there is no thinking at all. This is the experience of true emptiness. Before thinking, there are no words and no speech. So there are no mountains, no rivers, no God, no Buddha, nothing at all.
Next is the area up to 270°, the area of magic and miracles. Here, there is complete freedom, with no hindrance in space or time.
If you stay at 180°, you become attached to emptiness. If you stay at 270°, you become attached to freedom. At 360°, all things are just as they are; the truth is just like this. ‘Like this’ means that there is no attachment to anything.
This point is exactly the same as the zero point: we arrive where we began, where we have always been. The difference between 0° and 360° is no-attachment thinking.
