Yes, but didn't he get it from Bill Hamilton? I guess I should have asked, does the "Vipassana Jhana" concept originate with Bill Hamilton.
In the book Daniel presents several models of the Vipassana Jhanas, one is based on Bill Hamilton, one seems to be a fractal elaboration on that and one that is based on the teachings of U Pandita (p. 227) which is different from the previous ones. I think I've heard references to U Pandita's model in other works as well but I don't know how mainstream it is. Check out Chapter 5 in U Pandita's book "In this Very Life." -
