Connected Discourses on the Path
166. Barrenness
“Bhikkhus, there are these three kinds of barrenness. What three? The barrenness of lust, the barrenness of hatred, the barrenness of delusion. These are the three kinds of barrenness. The Noble Eightfold Path is to be developed for direct knowledge of these three kinds of barrenness, for the full understanding of them, for their utter destruction, for their abandoning.”
