Does a quiet mind mean focussing attention one-pointedly on a particular subject? As for instance, while aspiring one should not allow any other thoughts than of the Divine in the quiet mind.
A quiet mind is a mind that does not get disturbed, is not restless and always vibrating with the need of mental action.
What you are talking about is a concentrated mind, concentrated on something or on a subject. That is quite different.
