The Importance of Observing Impermanence

When nothing is occurring just keep your awareness on your breath. But when something arises that claims your attention just observe it from the perspective of this isn't going to bring me lasting happiness, fulfillment. This is changing and unreliable.

And it's meant to create a kind of clear scene that allows us to cut through the denial that clouds are awareness most of the time.
