For as long as the Source entrusts something to your hands, treat it as something borrowed, like a traveller at an inn.

26. The will of nature may be learned from those things in which we don’t distinguish from each other. For example, when our neighbor’s boy breaks a cup, or the like, we are presently ready to say, “These things will happen.” Be assured, then, that when your own cup likewise is broken, you ought to be affected just as when another’s cup was broken. Apply this in like manner to greater things. Is the child or wife of another dead? There is no one who would not say, “This is a human accident.” but if anyone’s own child happens to die, it is presently, “Alas I how wretched am I!” But it should be remembered how we are affected in hearing the same thing concerning others.

Yet God hath not only granted these faculties, by which we may bear every event without being depressed or broken by it, but like a good prince and a true father, hath placed their exercise above restraint, compulsion, or hindrance, and wholly within our own control.
