“I am spirit.“
Spirit is your true nature.
The text speaks of a split identity. A split identity is the result of a state of mind that is in allegiance with form, whether it is the body, a circumstance, or the way things appear. All that an appearance is, is an effect, a result. It functions as a mirror, showing you what is active in your mind. That is all. It is already in the past when you become aware of it. Form has no power other than that which you grant it by gingering it up through your creative attention.
You are not an effect, you are cause. Your true nature is Spirit and Spirit flows into the world as Love, Light, Peace and like qualities. Offer up to your inner guidance anything you notice that does not speak of Spirit and allow yourself to be led. Then you will experience the one Light that you are and that everyone and everything else is.
