Lakkhaṇa sutta: Characteristics

“A fool is characterized by their deeds, and an astute person is characterized by their deeds, for wisdom shines in its traces. A fool is known by three things. What three? Bad conduct by way of body, speech, and mind.

These are the three things by which a fool is known.

An astute person is known by three things. What three? Good conduct by way of body, speech, and mind.

These are the three things by which an astute person is known.

So you should train like this: ‘We will shun the three things by which a fool is known, and we will proceed having undertaken the three things by which an astute person is known.’ That’s how you should train.”
