The teachings on the Course are non-dualistic teachings. In the event you return into ancient China or again into India, you would have heard of Advaita Vedanta. Advaita truly usually means “not two,” and that's a method of talking about the fact that there's a oneness which connects us all. https://www.youtube.com/channel/UCTleG6-484F7WHZD0hAjRRw
