[367] And what, bhikkhus, is the nutriment (āhāra) for the arising of the unarisen energy factor of awakening (vīriyasambojjhaṅga), and for the development and fulfillment of the arisen energy factor of awakening? There is, bhikkhus, the element of arousal (ārabbhadhātu), the element of exertion (nikkamadhātu), and the element of persistence (parakkamadhātu): frequently giving careful attention (yoniso manasikāra) to these — this is the nutriment for the arising of the unarisen energy factor of awakening, and for the development and fulfillment of the arisen energy factor of awakening.
