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