Sickness is an impediment to the body, but not to the will unless itself
pleases. Lameness is an impediment to the leg, but not to the will; and
say this to yourself with regard to everything that happens. For you will
find it to be an impediment to something else, but not truly to yourself.

Upon every accident, remember to turn toward yourself and inquire what
faculty you have for its use. If you encounter a handsome person, you
will find continence the faculty needed; if pain, then fortitude; if
reviling, then patience. And when thus habituated, the phenomena of
existence will not overwhelm you.
