The teachings with the Course are non-dualistic teachings. In the event you go back into historical China or back into India, you would've heard of Advaita Vedanta. Advaita truly implies “not two,” and that's a method of referring to the fact that there is a oneness which connects us all. https://www.youtube.com/channel/UCTleG6-484F7WHZD0hAjRRw
