If then you do not make yourself equal to God, you cannot
apprehend God; for like is known by like. Leap clear of all that is
corporeal, and make yourself grown to a like expanse with that
greatness which is beyond all measure; rise above all time and
become eternal; then you will apprehend God. Think that for you
too nothing is impossible; deem that you too are immortal, and
that you are able to grasp all things in your thought, to know every
craft and science; find your home in the haunts of every living
creature; make yourself higher than all heights and lower than all
depths; bring together in yourself all opposites of quality, heat
and cold, dryness and fluidity; think that you are everywhere at
once, on land, at sea, in heaven; think that you are not yet
begotten, that you are in the womb, that you are young, that you are
old, that you have died, that you are in the world beyond the grave;
grasp in your thought all of this at once, all times and places, all
substances and qualities and magnitudes together; then you can
apprehend God. But if you shut up your soul in your body, and
abase yourself, and say "I know nothing, I can do nothing; I
am afraid of earth and sea, I cannot mount to heaven; I know
not what I was, nor what I shall be," then what have you to do
with God?

I've been reading about a Taoist meditation system that I am about to start. The main and eventual goal is to realize your true self and merge with the Tao. Whether you call the Tao God or consider them two separate things would probably determine the relevance of the last two sentences, though.
