At Sāvatthī.

“Mendicants, there are these four elements. What four? The elements of earth, water, fire, and air. There are ascetics and brahmins who don’t truly understand these four elements’ gratification, drawback, and escape for what they are. I don’t regard them as true ascetics and brahmins. Those venerables don’t realize the goal of life as an ascetic or brahmin, and don’t live having realized it with their own insight.
