“Good, mendicants! I too have never seen or heard of such a thing.
So you should train like this: ‘We will guard our sense doors, eat in moderation, be dedicated to wakefulness, discern skillful qualities, and pursue the development of the qualities on the side of awakening in the evening and toward dawn.’ That’s how you should train.”
Numbered Discourses 6.18 2. Warm-hearted A Fish Dealer
At one time the Buddha was wandering in the land of the Kosalans together with a large Saṅgha of mendicants.
While walking along the road he saw a fish dealer in a certain spot selling fish that he had killed himself. Seeing this he left the road, sat at the root of a tree on the seat spread out, and addressed the mendicants: “Mendicants, do you see that fish dealer selling fish that he killed himself?”
“Yes, sir.”
“What do you think, mendicants? Have you ever seen or heard of a fish dealer selling fish that he killed himself who, by means of that work and livelihood, got to travel by elephant, horse, chariot, or vehicle, or to enjoy wealth, or to live off a large fortune?”
“No, sir.”
