SENECA, Letters from a Stoic, Letter XCI

“One thing I know: all the works of mortal man lie under sentence of mortality; we live among things that are destined to perish...So the spirit must be trained to a realization and an acceptance of its lot...There's no ground for resentment in all this. We've entered into a world in which these are the terms life is lived on...Resent a thing by all means if it represents an injustice decreed against yourself personally; but if this same constraint is binding on the lowest and the highest alike, then make your peace with destiny, the destiny that unravels all ties.”
