Impermanence

At Sāvatthī.
“Mendicants, you should give up desire for what is impermanent.
And what is impermanent?
Form is impermanent; you should give up desire for it.
Feeling …
Perception …
Choices …
Consciousness is impermanent; you should give up desire for it.
You should give up desire for what is impermanent.”
