Awareness of thinking

The practice of the Dhamma is such that you must come to this point where you know the knowing mind, awareness; being aware of your awareness.

Every practice must come to this point.

Knowing mind is the mind that knows the object, watching
mind or ‘one step up mind’ is the one that knows of both of them.

Most people don’t know the knowing mind and don’t get to the point where they can see the knowing mind that knows the object..
If you don’t see how the mind works, you don’t know how the
mind creates these concepts. Concepts are created by the mind.

If you do not see that the concept is created by the mind, you can’t stop it. (i.e. when we sit and we think that our bodies are going very big or very small and we don’t know that the mind is imagining this).
