Whether the brain can be quiet

Meditation is to find out whether the brain, with all its activities, all its experiences, can be absolutely quiet. Not forced, because the moment you force, there is duality. The entity that says, “I would like to have marvellous experiences, therefore I must force my brain to be quiet” will never do it.
But if you begin to inquire, observe, listen to all movements of thought, its conditioning, its pursuits, its fears, its pleasures,
watch how the brain operates, then you will see that the brain becomes extraordinarily quiet; that quietness is not sleep but it is tremendously active and therefore quiet. A big dynamo that is working perfectly hardly makes a sound; it is only when there is friction that there is noise. By: J.Krishnamrti,  from his: Meditations, p 4
