May I commend S&H 409:9-10 and 19-20. The human mortal mind, or matter, is always unconscious because “All consciousness is Mind, and Mind is God” (Ret. 56:18). Unconsciousness cannot dictate terms to consciousness.
If you look up S&H 372:1 only, and 259:24-26 you will see that brain (unconscious mind) never formed even a human concept. A brain concept, relying on nerves as messengers, is nothing at all. A human concept is not something in its own right either, but is a limited sense of that which is divine. So neither a brain concept nor a human concept has ever been a part of your make-up. You live as Mind in self-expression.
