Connected Discourses on the Establishments of Mindfulness

35. Mindful

At Savatthi. “Bhikkhus, a bhikkhu should dwell mindful and clearly comprehending. This is our instruction to you.

“And how, bhikkhus, is a bhikkhu mindful? Here, bhikkhus, a bhikkhu dwells contemplating the body in the body … 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.

“And how, bhikkhus, does a bhikkhu exercise clear comprehension? Here, bhikkhus, for a bhikkhu feelings are understood as they arise, understood as they remain present, understood as they pass away. Thoughts are understood as they arise, understood as they remain present, understood as they pass away. Perceptions are understood as they arise, understood as they remain present, understood as they pass away. It is in this way, bhikkhus, that a bhikkhu exercises clear comprehension.

“Bhikkhus, a bhikkhu should dwell mindful and clearly comprehending. This is our instruction to you.”
