The teachings of the Course are non-dualistic teachings. In case you go back into historical China or back into India, you would've heard about Advaita Vedanta. Advaita really means “not two,” and that's a technique for speaking about the fact that there's a oneness which connects us all. It's important. https://www.youtube.com/channel/UCTleG6-484F7WHZD0hAjRRw
