Lecture I

The Moon not only mirrors sunlight, but also reflects everything that radiates upon it, although sunlight is by far the strongest. All the heavenly bodies in the universe send their rays toward the Moon, and the Moon, as a mirror of the universe, then radiates it all back in every direction. It can be said, therefore, that the universe is before us in a twofold aspect. It reveals itself directly on Earth, but also in what is radiated back by the Moon. The Sun's rays work with tremendous power in themselves, but also in their reflection from the Moon. Every other radiation in cosmic space is also reflected by the Moon. There is the manifest universe, and there is also its reflection from the Moon.
