The Long Āgama Sūtra 13.25

13.25

「阿難！我以此緣，知護由守，因守有護，我所說者，義在於此。阿難！因嫉有守，此為何義？若使一切眾生無有嫉者，寧有守不？」

“Ānanda, it’s for this reason that we know safeguards come from guarding. ‘Safeguards exist conditioned by guarding.’ That’s the meaning of what I said.

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