The eye does not go there, nor speech, nor mind. We do no know That. We do know how to instruct one about It. It is distinct from the known and above the unknown.
What speech cannot reveal but what reveals speech, know That alone as Brahman
What one cannot feel with the mind, but because of which they say that the mind feels know That alone as Brahman.
What cannot be seen by the eye but by which the eyes are able to see know That alone as Brahman.
He understands Brahman who comprehends It not; and understands It not who feel he has comprehended It.
