accept the thought, don't Entertain it — "Let them come as they will…"
Let them come as they will, but do not Entertain them. No need to invite a Substance-thought or -memory in, offer it a tonic and your favorite chair, and chat with it about old times.
Context
The program's actual working technology, and the theme's answer to its own central problem: you can't stop the cravings — they rise unbidden, lifelong, like bubbles — so the discipline is not suppression but hospitality withheld. Let the thought come and go; just don't seat it, pour it a drink, and reminisce. It is the Abiding doctrine applied to the mind's own traffic, the refusal to Entertain the Substance-memory that "clamors" to be entertained.
