sn.45.171 Saṁyutta Nikāya (Linked Discourses)

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