You think that when the mind starts to be aware, the mind immediately runs away (awareness is immediately lost).

No. When you’re immediately aware (when awareness returns), awareness can see that the mind is thinking. The mind doesn’t immediately go away.

When you’re aware, you can see the thinking mind. But your idea is that when you start to be aware, the awareness immediately goes away.

No, it is because you’re aware that awareness can see the thinking mind happening.

That’s why awareness is already there.
