“Bhikkhus, a bhikkhu should dwell mindful. This is our instruction to you.

“And how, bhikkhus, is a bhikkhu mindful? Here, bhikkhus, a bhikkhu dwells contemplating the body in the body, ardent, clearly comprehending, mindful, having removed covetousness and displeasure in regard to the world. He dwells contemplating feelings in feelings … mind in mind … phenomena in phenomena, ardent, clearly comprehending, mindful, having removed covetousness and displeasure in regard to the world. It is in this way, bhikkhus, that a bhikkhu is mindful.
