Why this discourse

Irrational application of mind causes the five hindrances to arise and grow while making the seven awakening factors either fail to arise or, if already arisen, cease — and rational application of mind does the exact opposite in both respects simultaneously. This discourse states, in a single symmetric formula, the mechanism already explored in fuller detail at SN 46.2 and SN 46.23.

Reading guide

One mechanism, four simultaneous effects

Unlike SN 46.2's own item-by-item treatment or SN 46.23's own more generic restatement, this discourse compresses the entire mechanism into two mirrored halves: irrational attention simultaneously feeds the hindrances AND starves the awakening factors; rational attention simultaneously starves the hindrances AND feeds the awakening factors — confirmed by close reading to describe a single act of attention with a double, opposite effect depending on its own direction.

Key terms

ayoniso manasikaroto — “when you apply the mind irrationally” — the discourse's own opening condition, causing the five hindrances to arise and grow while suppressing the awakening factors
yoniso manasikaroto — “when you apply the mind rationally” — the mirrored condition, causing the opposite double effect
anuppannā ceva uppajjanti uppannā ca nirujjhanti — “[the awakening factors] don't arise, or if they've already arisen, they cease” — the specific double consequence of irrational attention for the awakening factors
kāmacchando... vicikicchā — the five hindrances, named as what irrational attention feeds and rational attention starves
satisambojjhaṅgo... upekkhāsambojjhaṅgo — the seven awakening factors, named as what rational attention feeds and irrational attention starves

The text

The complete discourse, both mirrored halves in full. Translation: Bhikkhu Sujato (CC0, SuttaCentral).

§1 — irrational application of mind“Mendicants, when you apply the mind irrationally, sensual desire, ill will, dullness and drowsiness, restlessness and remorse, and doubt arise, and once arisen they increase and grow. And the awakening factors of mindfulness, investigation of principles, energy, rapture, tranquility, immersion, and equanimity don’t arise, or if they’ve already arisen, they cease.

§2 — rational application of mindWhen you apply the mind rationally, sensual desire, ill will, dullness and drowsiness, restlessness and remorse, and doubt don’t arise, or if they’ve already arisen they’re given up. And the awakening factors of mindfulness, investigation of principles, energy, rapture, tranquility, immersion, and equanimity arise, and once they’ve arisen, they’re fully developed.”
