The teachings in the Course are non-dualistic teachings. In case you go back into historic China or back into India, you might have heard about Advaita Vedanta. Advaita essentially signifies “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
