The Sierpinski gasket's vertices are the three addiction narratives (JOI / Hal / Gately), converging on God at the empty center

In plain terms: the book's shape is a Sierpinski gasket whose three points are the addiction stories (JOI, Hal, Gately), converging on God at the empty center.

Where the text lands: the underlying fractal-recursion idea is the best-supported reading; the specific assignment of the three addiction narratives to the gasket's points is a stretch. Among readers: a split on what the shape's elements actually are; agreement only on the fractal-recursion baseline.

The author named a shape of the manuscript but assigned no meaning to its points, so the addiction-triad mapping rests on inference plus a whole-book premise, with the convergence located beyond the last page. A noted counter is that a gasket looks the same from any starting point, which makes the substrate non-discriminating. See Structure and Hamlet.
