I think meditation is a way of being nice to our right hemisphere. Our left hemisphere is responsible for speech, and our right hemisphere is mute. Be nice to your right hemisphere, it's you too, and it doesn't like listening to your jibber-jabber.
On a semi-related note, I think the movie 'Us' by Jordan Peele is about our split-minds. The protagonists are the left-hemispheres, and the clones are our right hemispheres (they cannot speak).
