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