Then Sāriputta went up to the Buddha, bowed, sat down to one side, and said to him, “Sir, I have such confidence in the Buddha that I believe there’s no other ascetic or brahmin—whether past, future, or present—whose direct knowledge is superior to the Buddha when it comes to awakening.”

“That’s a grand and dramatic statement, Sāriputta. You’ve roared a definitive, categorical lion’s roar, saying: ‘I have such confidence in the Buddha that I believe there’s no other ascetic or brahmin—whether past, future, or present—whose direct knowledge is superior to the Buddha when it comes to awakening.’

What about all the perfected ones, the fully awakened Buddhas who lived in the past? Have you comprehended their minds to know that those Buddhas had such ethics, or such qualities, or such wisdom, or such meditation, or such freedom?”

“No, sir.”

“And what about all the perfected ones, the fully awakened Buddhas who will live in the future? Have you comprehended their minds to know that those Buddhas will have such ethics, or such qualities, or such wisdom, or such meditation, or such freedom?”

“No, sir.”

“And what about me, the perfected one, the fully awakened Buddha at present? Have you comprehended my mind to know that I have such ethics, or such teachings, or such wisdom, or such meditation, or such freedom?”

“No, sir.”

“Well then, Sāriputta, given that you don’t comprehend the minds of Buddhas past, future, or present, what exactly are you doing, making such a grand and dramatic statement, roaring such a definitive, categorical lion’s roar?”

“Sir, though I don’t comprehend the minds of Buddhas past, future, and present, still I understand this by inference from the teaching. Suppose there was a king’s frontier citadel with fortified embankments, ramparts, and arches, and a single gate. And it has a gatekeeper who is astute, competent, and intelligent. He keeps strangers out and lets known people in. As he walks around the patrol path, he doesn’t see a hole or cleft in the wall, not even one big enough for a cat to slip out. He thinks: ‘Whatever sizable creatures enter or leave the citadel, all of them do so via this gate.’

In the same way, I understand this by inference from the teaching: ‘All the perfected ones, fully awakened Buddhas—whether past, future, or present—give up the five hindrances, corruptions of the heart that weaken wisdom. Their mind is firmly established in the four kinds of mindfulness meditation. They correctly develop the seven awakening factors. And they wake up to the supreme perfect awakening.’”

And while staying at Nāḷandā, too, the Buddha often gave this Dhamma talk to the mendicants:

“Such is ethics, such is immersion, such is wisdom. When immersion is imbued with ethics it’s very fruitful and beneficial. When wisdom is imbued with immersion it’s very fruitful and beneficial. When the mind is imbued with wisdom it is rightly freed from the defilements, namely, the defilements of sensuality, desire to be reborn, and ignorance.”
