Insight about our unity with God from the Corpus Hermeticum.
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 grow 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 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 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 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, not what I shall be”; then, what have you to do with God? Your thought can grasp nothing beautiful and good, if you cleave to the body, and are evil.
For it is the height of evil not to know God; but to be capable of knowing God, and to wish and hope to know him, is the road which leads straight to the Good; and it is an easy road to travel. Everywhere God will come to meet you, everywhere he will appear to you, at places and times at which you look not for it, in your waking hours and in your sleep, when you are journeying by water and by land, in the nighttime and in the daytime, when you are speaking and when you are silent; for there is nothing which is not God. And do you say “God is invisible?” Speak not so. Who is more manifest than God? For this very purpose has he made all things. Nothing is invisible, not even an incorporeal thing; mind is seen in its liking, and God in his working.
So far, I have shown you the truth. Think out all else in like manner for yourself, and you will not be misled.
