Meditations 7:16

The mind doesn't get in its own way. It doesn't frighten itself into desires. If other things can scare or hurt it, let them;

it won't go down that road on the basis of its own perceptions.

Let the body avoid discomfort (if it can), and if it feels it, say so. But the soul is what feels fear and pain, and what conceives of them in the first place, and it suffers nothing.

Because it will never conclude that it has.

The mind in itself has no needs, except for those it creates itself. Is undisturbed, except for its own disturbances. Knows no obstructions, except those from within.
