Then the wanderer Potaliya went up to the Buddha, and exchanged greetings with him. When the greetings and polite conversation were over, he sat down to one side, and the Buddha said to him:

“Potaliya, these four individuals are found in the world. What four? One individual criticizes those deserving of criticism at the right time, truthfully and correctly. But they don’t praise those deserving of praise at the right time, truthfully and correctly. Another individual praises those deserving of praise … But they don’t criticize those deserving of criticism … Another individual doesn’t praise those deserving of praise … Nor do they criticize those deserving of criticism … Another individual criticizes those deserving of criticism at the right time, truthfully and correctly. And they praise those deserving of praise at the right time, truthfully and correctly. These are the four individuals found in the world. Of these four individuals, who do you believe to be the finest?”
