There is only one I. I am the one I am which is God, spirit, truth. The “I” referred to throughout the Scriptures of the world is your I—your entirety, your consciousness.
The one I is the I you are and the I I am—just as the “I” the sun is is the same “I” the sunbeam is.
From Chapter 11, What Is Consciousness?
