The practice of sitting quietly with your eyes closed in meditation is useful in that, with steady attention, you can realize that all of this mental stuff is something that can be watched, and that it is therefore a series of objects – not the subject, not self.
That understanding in itself takes some of the drama out of the show, and as the mind stops feeding on contact, it steps back into balance and quiets down.
