Don’t try too hard. If “All is infinite Mind and its infinite manifestation…” (S&H 568:10-11) then that is true now. It means that error is not a power to be overcome because this would deny all. It means that error is just ignorance to be offset by the understanding of Truth.
This really means Truth’s understanding of itself, and Truth unfolds irresistibly as your consciousness, bathing your whole experience in a new light.
This moment all there is to you is I, Mind, knowing My one infinite manifestation.
You cannot know about Mind, you can only know as Mind, for one Mind means one thinker and one capacity to know. You subordinate the false, limited, material sense of things with the Mind you have and are; but you do not start off with any other mind than God.
