"Shadows in the astral world are projections of copies of the forms of things in that world. The forms of the astral world are projections or shadows-not copies---of thoughts in the mental world. Thoughts in the mental world are emanations from the minds in that world. The thoughts or emanations in the mental world are projections by the light of the spiritual world, of the types of the spiritual world through the minds acting in the mental world. The physical objects in the physical world are the shadows of the forms in the astral world. The forms of the astral world are the shadows of thoughts in the mental world. The thoughts and ideals of the mental world are the shadows of the types or ideas in the spiritual world."
