I followed that path...

"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 aspiration, right speech, right action, right livelihood, right effort, right mindfulness, right concentration. That is the ancient path, the ancient road, traveled by the Rightly Self-awakened Ones of former times. I followed that path. Following it, I came to direct knowledge of aging & death, direct knowledge of the origination of aging & death, direct knowledge of the cessation of aging & death, direct knowledge of the path leading to the cessation of aging & death. 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.
