The teachings from the Course are non-dualistic teachings. In the event you go back into ancient China or again into India, you might have heard of Advaita Vedanta. Advaita actually means “not two,” and that's a means of referring to the fact that there's a oneness which connects us all. https://www.youtube.com/channel/UCTleG6-484F7WHZD0hAjRRw
