At Sāvatthī.

“Mendicants, when a noble disciple has quelled five dangers and threats, has the four factors of stream-entry, and has clearly seen and comprehended the noble system with wisdom, they may, if they wish, 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.’

What are the five dangers and threats they have quelled? Killing living creatures … stealing … sexual misconduct … lying … taking alcoholic drinks that cause negligence … These are the five dangers and threats they have quelled.

What are the four factors of stream-entry that they have? It’s when a noble disciple has experiential confidence in the Buddha … the teaching … the Saṅgha … and their ethical conduct is loved by the noble ones. These are the four factors of stream-entry that they have.

And what is the noble system that they have clearly seen and comprehended with wisdom? A noble disciple carefully and rationally applies the mind to dependent origination itself … This is the noble system that they have clearly seen and comprehended with wisdom.

When a noble disciple has quelled five dangers and threats, has the four factors of stream-entry, and has clearly seen and comprehended the noble system with wisdom, they may, if they wish, 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.’”
