Simply do this:

Be still, and lay aside all thoughts of what you are
and what God is; all concepts you have learned
about the world; all images you hold about yourself.

Empty your mind of everything it thinks
is either true or false, or good or bad, of every thought it judges
worthy, and all the ideas of which it is ashamed.

Hold onto nothing.

Do not bring with you one thought the past has taught,
nor one belief you ever learned before from anything.

Forget this world, forget this course, and come
with wholly empty hands unto your God.
