'And this, monks, is the noble truth of the way of practice leading to the cessation of dukkha: precisely this Noble Eightfold Path: right view, right resolve, right speech, right action, right livelihood, right effort, right mindfulness, right concentration.'

The threefold division of the path

[Visakha, a layman, ex-husband of Ven. Sister Dhammadinna:] 'And are the three aggregates [of virtue, concentration, discernment] included under the noble eightfold path, lady, or is the noble eightfold path included under the three aggregates?'

[Ven. Sister Dhammadinna:] 'The three aggregates are not included under the noble eightfold path, friend Visakha, but the noble eightfold path is included under the three aggregates. Right speech, right action, & right livelihood come under the aggregate of virtue. Right effort, right mindfulness, & right concentration come under the aggregate of concentration. Right view & right resolve come under the aggregate of discernment.'

An ancient path rediscovered

'It is just as if a man, traveling along a wilderness track, were to see an ancient path, an ancient road, traveled by people of former times. He would follow it. Following it, he would see an ancient city, an ancient capital inhabited by people of former times, complete with parks, groves, & ponds, walled, delightful. He would go to address the king or the king's minister, saying, 'Sire, you should know that while traveling along a wilderness track I saw an ancient path... I followed it... I saw an ancient city, an ancient capital... complete with parks, groves, & ponds, walled, delightful. Sire, rebuild that city!' The king or king's minister would rebuild the city, so that at a later date the city would become powerful, rich, & well-populated, fully grown & prosperous.

'In the same way I saw an ancient path, an ancient road, traveled by the Rightly Self-awakened Ones of former times. And what is that ancient path, that ancient road, traveled by the Rightly Self-awakened Ones of former times? Just this noble eightfold path: right view, right resolve, right speech, right action, right livelihood, right effort, right mindfulness, right concentration... I followed that path. Following it, I came to direct knowledge of birth... becoming... clinging... craving... feeling... contact... the six sense media... name-&-form... consciousness, direct knowledge of the origination of consciousness, direct knowledge of the cessation of consciousness, direct knowledge of the path leading to the cessation of consciousness. I followed that path.

'Following it, I came to direct knowledge of fabrications, direct knowledge of the origination of fabrications, direct knowledge of the cessation of fabrications, direct knowledge of the path leading to the cessation of fabrications. Knowing that directly, I have revealed it to monks, nuns, male lay followers & female lay followers, so that this holy life has become powerful, rich, detailed, well-populated, wide-spread, proclaimed among celestial & human beings.'

Enlightenment is accessible only to those who follow this path

'In any doctrine & discipline where the noble eightfold path is not found, no contemplative of the first... second... third... fourth order [stream-winner, once-returner, nonreturner, or arahant] is found. But in any doctrine & discipline where the noble eightfold path is found, contemplatives of the first... second... third... fourth order are found. The noble eightfold path is found in this doctrine & discipline, and right here there are contemplatives of the first... second... third... fourth order. Other teachings are empty of knowledgeable contemplatives. And if the monks dwell rightly, this world will not be empty of arahants.'
