2.362

正法念經云。一少年。二安隱。三壽命。四具足（具足即是富貴）如是四法。必定別離。智者常須觀察。

The Saddharmasmṛtyupasthāna-sūtra states: "First, youth; second, peace; third, lifespan; fourth, abundance (abundance means wealth and status). From these four dharmas, there must inevitably be separation; the wise should always contemplate this."
