A Brahman named Sangarava bathed every morning and evening in the river so that he could be cleansed from whatever sin he might have committed during the day.
To him, the Buddha said, "If bathing could purify one from sins, then all the frogs, turtles, and crocodiles would be free from sin! The real lake is the lake of goodness, with grace as its shore for bathing. Clear and undefiled, it soothes all who immerse themselves. Plunge into the waters of goodness and learn to swim."
