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