Ogha sutta - Flood

At Sāvatthi.

"Bhikkhus, there are these four floods [of defilements]. What four? The flood of sensual pleasures, the flood of continued existence, the flood of views, and the flood of ignorance. These are the four floods.

Bhikkhus, for the direct knowing, full understanding, complete exhaustion, and for giving up of these four floods, the Noble Eightfold Path should be developed."
