Dhawal Ramdham's Key Ideas from Meditations
by Marcus Aurelius

For the present is the same to all, through that which perishes is not the same; and so that which is lost appears to be a mere moment.

For a man cannot lose either the past or the future: for what a man has not, how can anyone take this from him?

For to be vexed at anything that happens.

Turn towards someone with the intention of injuring.

When it's overpowered by pleasure or by pain.

Does or says anything insincerely and untruly.

When it allows any act of its own to be without an aim.
