At one time the Buddha was staying near Varanasi 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 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 understood 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 purpose, 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.
