### Religions

• ZEN circle, states of ZEN student mind 0°, 90°, 180°, 270°, 360°

This circle is divided into four parts.

The first part is from 0 degrees to 90 degrees. In this part 1 + 2 = 3. The mind is attached to it’s thinking, it clings to conceptions and has much suffering. Here there is name and form attachment.

From 90 degrees to 180 degrees the mind understands that all things that have appearance are transient. So form is emptiness, emptiness is form. 1=0 0=1. Do you understand? Before you were born you were 0. Now you are 1. In the future you will die and you will again be 0. Therefore, form is empty, emptiness is form.

At 180 degrees you are nothing, there is only emptiness, so there is no Buddha, no Universe, no energy, no God, no you, no I. Many people have conceptions of oneness. For them Buddha, Universal Energy, and God are all One. So, they have an emptiness attachment. This emptiness attachment is thinking. You have an emptiness attachment.
