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