sn.45.163 Saṁyutta Nikāya (Linked Discourses)

“Bhikkhus, there are these three taints. What three? The taint of sensuality, the taint of existence, the taint of ignorance. These are the three taints. The Noble Eightfold Path is to be developed for direct knowledge of these three taints, for the full understanding of them, for their utter destruction, for their abandoning.”
