The angel had told me in my dream that if I wanted to acquire the perfect knowledge I desired, I would have to go to the Moon. There I would find Adam's paradise and the Tree of Knowledge. As soon as I had tasted its fruit, my mind would be enlightened with all the truths a person could know. That is the voyage for which I built my chariot.
Finally, I climbed aboard and, when I was securely settled on the seat, I tossed the magnetic ball high into the air. The chariot I had built was more massive in the middle than at the ends; it was perfectly balanced because the middle rose faster than the extremities. When I had risen to the point that the magnet was drawing me to, I seized the magnetic ball and tossed it into the air again.
