There is a Middle Path
2. ‘There are two extremes, O Bhikkhus, which the man who has given up the world ought not to follow–the habitual practice, on the one hand of those things whose attraction depends upon the passions, and especially of sensuality–a low and pagan way (of seeking satisfaction) unworthy, unprofitable, and fit only for the worldly-minded–
3. ‘There is a middle path, O Bhikkhus, avoiding these two extremes, discovered by the Tathâgata–a path which opens the eyes, and bestows understanding, which leads to peace of mind, to the higher wisdom, to full enlightenment, to Nirvâna!
