[19] Bhikkhus, I do not see even one other thing by which unarisen dullness and drowsiness (thīna-middha) does not arise, or by which arisen dullness and drowsiness is abandoned, so much as this: the element of instigation (ārambhadhātu), the element of persistence (nikkamadhātu), the element of exertion (parakkamadhātu). Bhikkhus, for one whose energy (vīriya) is aroused, unarisen dullness and drowsiness does not arise, and arisen dullness and drowsiness is abandoned.
