“No private thoughts” is one of the guidelines at the Living Miracles Monastery. This clip from a retreat at the Monastery gives the metaphysics underneath this and how there literally are no private thoughts. The metaphysical understanding of ACIM is necessary as a prerequisite to understanding the metaphysics of “no private thoughts.” ACIM uses an educational approach to teach the mind the spiritual metaphysics and the metaphysical definitions that are needed to train the mind to awaken to reality. All of this will be transcended when the meaning of metaphysics is fully grasped and the experience that the metaphysics is pointing to is experienced.
