"Now when a monk... attending to another theme... scrutinizing the drawbacks of those thoughts... paying no mind and paying no attention to those thoughts... attending to the relaxing of thought-fabrication with regard to those thoughts... beating down, constraining and crushing his mind with his awareness... steadies his mind right within, settles it, unifies it and concentrates it: He is then called a monk with mastery over the ways of thought sequences. He thinks whatever thought he wants to, and doesn't think whatever thought he doesn't. He has severed craving, thrown off the fetters, and — through the right penetration of conceit —
has made an end of suffering and stress."
That is what the Blessed One said. Gratified, the monks delighted in the Blessed One's words.
