The doorway

If you see a inside and outside (in other words the subject and the object, the "me" and the outside world), and there is the doorway. That doorway is "mind". The only thing that needs to be done is to remove the doorway. What happens after the removal of the doorway? Now, how remove a imaginary doorway? Can it be done?

No, because it's an imagination, a mirage.

But if you take a close look, make an investigation. What happens?

What happens to a mirage when it's been looked upon very closely?

Se it for your Self.
