Mindful

At Sāvatthī.

“Bhikkhus, a bhikkhu should live mindful and aware. This is my instruction to you.

And how is a bhikkhu mindful? It’s when a bhikkhu meditates by observing an aspect of the body—keen, aware, and mindful, rid of covetousness and displeasure for the world. They meditate observing an aspect of feelings … mind … principles—keen, aware, and mindful, rid of covetousness and displeasure for the world. That’s how a bhikkhu is mindful.

And how is a bhikkhu aware? It’s when a bhikkhu knows feelings as they arise, as they remain, and as they go away. They know thoughts as they arise, as they remain, and as they go away. They know perceptions as they arise, as they remain, and as they go away. That’s how a bhikkhu is aware. A bhikkhu should live mindful and aware. This is my instruction to you.”
