2.p151

“Ānanda, a monk observes body internally [to be body.] Diligent and unflagging, he’s mindful and doesn’t forget it, setting aside worldly greed and sorrow. He observes body externally … observes body internally and externally … Diligent and unflagging, he’s mindful and doesn’t forget it, setting aside worldly greed and sorrow. He also observes feelings, mind, and principles in the same way. That’s how, Ānanda, one lights themselves, lights the Dharma, and doesn’t light something else. One must take refuge in themselves, take refuge in the Dharma, and not take refuge in something else.”
