It’s hardly surprising that a human being should pass away. But if you should come and ask me about it each and every time someone passes away, that would be a bother for me.

So Ānanda, I will teach you the explanation of the Dhamma called ‘the mirror of the teaching’. A noble disciple who has this may declare of themselves: ‘I’ve finished with rebirth in hell, the animal realm, and the ghost realm. I’ve finished with all places of loss, bad places, the underworld. I am a stream-enterer! I’m not liable to be reborn in the underworld, and am bound for awakening.’

And what is that mirror of the teaching?

It’s when a noble disciple has experiential confidence in the Buddha: ‘That Blessed One is perfected, a fully awakened Buddha, accomplished in knowledge and conduct, holy, knower of the world, supreme guide for those who wish to train, teacher of gods and humans, awakened, blessed.’

They have experiential confidence in the teaching: ‘The teaching is well explained by the Buddha—visible in this very life, immediately effective, inviting inspection, relevant, so that sensible people can know it for themselves.’

They have experiential confidence in the Saṅgha: ‘The Saṅgha of the Buddha’s disciples is practicing the way that’s good, straightforward, methodical, and proper. It consists of the four pairs, the eight individuals. This is the Saṅgha of the Buddha’s disciples that is worthy of offerings dedicated to the gods, worthy of hospitality, worthy of a religious donation, worthy of greeting with joined palms, and is the supreme field of merit for the world.’

And a noble disciple’s ethical conduct is loved by the noble ones, unbroken, impeccable, spotless, and unmarred, liberating, praised by sensible people, not mistaken, and leading to immersion.

This is that mirror of the teaching.”

And while staying there in Nādika 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.”

When the Buddha had stayed in Nādika as long as he wished, he addressed Venerable Ānanda, “Come, Ānanda, let’s go to Vesālī.”

“Yes, sir,” Ānanda replied. Then the Buddha together with a large Saṅgha of mendicants arrived at Vesālī, where he stayed in Ambapālī’s mango grove.

There the Buddha addressed the mendicants:

“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 desire and aversion for the world. They meditate observing an aspect of feelings … mind … principles—keen, aware, and mindful, rid of desire and aversion 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 is aware. A mendicant should live mindful and aware. This is my instruction to you.”
