The Long Āgama Sūtra 13.33

13.33

「阿難，我以此義，知欲由用，因用有欲，我所說者，義在於此。阿難！因利有用，此為何義，若使一切眾生無有利者，寧有用不？」

“Ānanda, it’s for this reason that we know desire comes from use. ‘Desire exists conditioned by use.’ That’s the meaning of what I said.

“Ānanda, ‘use exists conditioned by profit.’ What does this mean? Suppose that no sentient being had any profit. Would there be something to use?”
