Hermetica

‎"Consider this for yourself: command your soul to travel to India, and it will be there faster than your command. Command it to cross over to the ocean, and again it will quickly be there, not as having passed from place to place but simply as being there. Command it even to fly up to heaven, and it will not lack wings. Nothing will hinder it, not the fire of the sun, nor the aether, nor the swirl nor the bodies of the other stars. Cutting through them all, it will fly to the utmost body. But if you wish to break through the universe itself and look upon the things outside (if, indeed, there is anything outside the cosmos), it is within your power.

"See what power you have, what quickness! If you can do these things, can God not do them? So you must think of God in this way, as having everything — the cosmos, himself, (the) universe — like thoughts within himself. Thus, unless you make yourself equal to God, you cannot understand God; like is understood by like.

"Make yourself grow to immeasurable immensity, outleap all body, outstrip all time, become eternity and you will understand God. Having conceived that nothing is impossible to you, consider yourself immortal and able to understand everything, all art, all learning, the temper of every living thing. Go higher than every height and lower than every depth. Collect in yourself all the sensations of what has been made, of fire and water, dry and wet; be everywhere at once, on land, in the sea, in heaven; be not yet born, be in the womb, be young, old, dead, beyond death. And when you have understood all these at once — times, places, things, qualities, quantities – then you can understand God."
