At one time the Buddha was staying near Benares, in the deer park at Isipatana. There the Buddha addressed the group of five mendicants:
“Mendicants, these two extremes should not be cultivated by one who has gone forth. What two? Indulgence in sensual pleasures, which is low, crude, ordinary, ignoble, and pointless. And indulgence in self-mortification, which is painful, ignoble, and pointless. Avoiding these two extremes, the Realized One woke up by understanding the middle way of practice, which gives vision and knowledge, and leads to peace, direct knowledge, awakening, and extinguishment.
And what is that middle way of practice? It is simply this noble eightfold path, that is: right view, right thought, right speech, right action, right livelihood, right effort, right mindfulness, and right immersion. This is that middle way of practice, which gives vision and knowledge, and leads to peace, direct knowledge, awakening, and extinguishment.
Now this is the noble truth of suffering. Rebirth is suffering; old age is suffering; illness is suffering; death is suffering; association with the disliked is suffering; separation from the liked is suffering; not getting what you wish for is suffering. In brief, the five grasping aggregates are suffering.
Now this is the noble truth of the origin of suffering. It’s the craving that leads to future rebirth, mixed up with relishing and greed, taking pleasure in various different realms. That is, craving for sensual pleasures, craving to continue existence, and craving to end existence.
Now this is the noble truth of the cessation of suffering. It’s the fading away and cessation of that very same craving with nothing left over; giving it away, letting it go, releasing it, and not adhering to it.
Now this is the noble truth of the practice that leads to the cessation of suffering. It is simply this noble eightfold path, that is: right view, right thought, right speech, right action, right livelihood, right effort, right mindfulness, and right immersion.
