雜阿含經 2.p2

2.p2

It was then that the Bhagavān addressed the monks, “One should correctly contemplate form, observe that form is impermanent, and truly know it. Why is that? Monks, when someone correctly contemplates form, observes it to be impermanent, and truly knows it, they stop desire and greed for form. When someone stops desire and greed, I say their mind is liberated.
