“Ayoniso, bhikkhave, manasikaroto anuppanno ceva kāmacchando uppajjati, uppanno ca kāmacchando bhiyyobhāvāya vepullāya saṁvattati; anuppanno ceva byāpādo uppajjati, uppanno ca byāpādo bhiyyobhāvāya vepullāya saṁvattati; anuppannañceva thinamiddhaṁ uppajjati, uppannañca thinamiddhaṁ bhiyyobhāvāya vepullāya saṁvattati; anuppannañceva uddhaccakukkuccaṁ uppajjati, uppannañca uddhaccakukkuccaṁ bhiyyobhāvāya vepullāya saṁvattati; anuppannā ceva vicikicchā uppajjati, uppannā ca vicikicchā bhiyyobhāvāya vepullāya saṁvattati; anuppanno ceva satisambojjhaṅgo nuppajjati, uppanno ca satisambojjhaṅgo nirujjhati …pe… anuppanno ceva upekkhāsambojjhaṅgo nuppajjati, uppanno ca upekkhāsambojjhaṅgo nirujjhati.

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.

Yoniso ca kho, bhikkhave, manasikaroto anuppanno ceva kāmacchando nuppajjati, uppanno ca kāmacchando pahīyati; anuppanno ceva byāpādo nuppajjati, uppanno ca byāpādo pahīyati; anuppannañceva thinamiddhaṁ nuppajjati, uppannañca thinamiddhaṁ pahīyati; anuppannañceva uddhaccakukkuccaṁ nuppajjati, uppannañca uddhaccakukkuccaṁ pahīyati; anuppannā ceva vicikicchā nuppajjati, uppannā ca vicikicchā pahīyati.

When 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.

Anuppanno ceva satisambojjhaṅgo uppajjati, uppanno ca satisambojjhaṅgo bhāvanāpāripūriṁ gacchati …pe… anuppanno ceva upekkhāsambojjhaṅgo uppajjati, uppanno ca upekkhāsambojjhaṅgo bhāvanāpāripūriṁ gacchatī”ti.

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.”
