Ed, you apparently missed the header, footer, and notice just after the image at the beginning of this article that it is about the use of inner spontaneous sound as a support for meditation. In fact, it’s a book on the subject. You should read it before snapping to judgements about its author or what my PhD and life experiences might be about. Clicking on either the header or the footer will get you to a good starting point. Clicking on the link after the image will take you to the TOC for the series of articles already deep within the book that this one is a part of.
