In plain words

Whoever meditates upon the mind as Brahman—steadfast himself, he attains steadfast worlds; firmly established, he attains firmly established worlds; unshaken, he attains unshaken worlds. As far as the reach of the mind extends, so far he enjoys complete freedom of movement, he who meditates upon the mind as Brahman. 'Is there anything greater than the mind, venerable sir?' 'Indeed, there is something greater than the mind.' 'That, venerable sir, please explain to me.'
