Principle of 編満の原理 henman no genri – Principle of completeness

I recently found a reference in Japanese to the principle of 編満の原理 henman no genri and had no idea what it meant. Internet searches come up empty, or very vague.

Does anyone have more on this?

I did find a reference to Yanagi Sōetsu and his book The Unknown Craftsman, but nothing in there jumps out in these precise terms.

I found another reference that vaguely mentioned it, paraphrased below

The Japanese Principle of Completion (編満の原理, Henman no Genri).

Refers to a Japanese traditional aesthetic and philosophical concept .

Mostly found in art, literature, and design, it reflects the idea that a work or expression may feel more complete and evocative when it is _not_ entirely explicit or finished— that is, when some aspects are left implied, open, or incomplete.

I've certainly seen wabi, sabi, all sorts of principles or such attributes, but this one escaped me.
