Mysticism and Philosophical Analysis (1978) by Steven T. Katz, p. 92; four centuries later the Christian mystic Meister Eckhart would make a very similar assertion: "The eye with which I see God is the same with which God sees me. My eye and God's eye is one eye, and one sight, and one knowledge, and one love."
