When you see a person weeping in sorrow either when a child goes abroad
or when he is dead, or when the man has lost his property, take care
that the appearance do not hurry you away with it, as if he were
suffering in external things. But straightway make a distinction in
your own mind, and be in readiness to say, it is not that which has
happened that afflicts this man, for it does not afflict another, but
it is the opinion about this thing which afflicts the man. So far as
words then do not be unwilling to show him sympathy, and even if it
happens so, to lament with him. But take care that you do not lament
internally also.
