Sati sutta: Mindful

At one time the Buddha was staying near Vesālī in Ambapālī’s Mango Grove. There the Buddha addressed the mendicants, “Mendicants!”

“Venerable sir,” they replied. The Buddha said this:

“Mendicants, a mendicant should live mindful and aware. This is my instruction to you.

And how is a mendicant mindful? It’s when a mendicant 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 mendicant is mindful.

And how is a mendicant aware? It’s when a mendicant acts with situational awareness when going out and coming back; when looking ahead and aside; when bending and extending the limbs; when bearing the outer robe, bowl and robes; when eating, drinking, chewing, and tasting; when urinating and defecating; when walking, standing, sitting, sleeping, waking, speaking, and keeping silent. That’s how a mendicant acts with situational awareness. A mendicant should live mindful and aware. This is my instruction to you.”
