"If he can perceive the astral or design body of his physical structure, he will see the interior condition of his physical body, which physical body is the visible and outward expression of the invisible and interior condition. When he looks at his shadow he, sees the interior condition of his body as plainly as he would see the expression on his face by looking into a mirror. Whereas in the mirror he sees by reflection and sees the parts reversed from right to left, his shadow is seen by projection or emanation and there is a sameness of the position."
