Are you kidding me? Tolle borrowed this idea from The Big Book of AA. https://medium.com/illumination/credit-where-credit-is-due-part-deux-d137ee0f3fb4

David, your story is excellent. I wouldn't expect you to have had any question in your mind as to Tolle's originality. One of the problems with the anonymity aspect of AA is that people are not aware of its literature. Tolle and his publishers do not get that latitude from me.
