Four shelves, a single book. Letting Go is filed by our catalogue under personal development, religion and spirituality, business and careers, and society all at once, and that spread is no indexing accident. It is the signature of a certain kind of writing, the sort that treats an inner mechanism as the thing which explains the outer world.
The byline itself sets the frame. Medical and doctoral credentials sit alongside the name, and the work carries the tone that tends to go with them: a system proposed, described and then applied, rather than a set of anecdotes loosely gathered. Whether that system convinces is a matter for the listener, but its ambition is not in doubt.
