[190] Then the Blessed One addressed the bhikkhus: "Bhikkhus, there are these four dangers to be expected by one going down into the water. What four? The danger of waves, the danger of crocodiles, the danger of whirlpools, the danger of fierce fish (susukā). These, bhikkhus, are the four dangers to be expected by one going down into the water. Even so, bhikkhus, there are these four dangers to be expected for a certain individual here who has gone forth from home into homelessness in this Dhamma and Discipline. What four? The danger of waves, the danger of crocodiles, the danger of whirlpools, the danger of fierce fish."
