Meditations 11:2

To acquire indifference to pretty singing, to dancing, to the martial arts: Analyze the melody into the notes that form it, and as you hear each one, ask yourself whether you're powerless against that. That should be enough to deter you.

The same with dancing: individual movements and tableaux. And the same with the martial arts.

And with everything—except virtue and what springs from it. Look at the individual parts and move from analysis to indifference.

Apply this to life as a whole.
