The teachings with the Course are non-dualistic teachings. For those who return into historical China or back again into India, you would have heard of Advaita Vedanta. Advaita truly implies “not two,” and that is a method of talking about the fact that there's a oneness which connects us all. https://www.youtube.com/channel/UCTleG6-484F7WHZD0hAjRRw
