What is the moral? You went on board, you set sail, you have made the port. Step ashore

From Meditations by Marcus Aurelius, Book III, Verse 3.

Hippocrates, after curing many sicknesses, himself fell sick and died. The Chaldean astrologers foretold the death of many persons, then the hour of fate overtook them also. Alexander, Pompeius, and Julius Caesar, after so often utterly destroying whole towns and slaying in the field many myriads of horse and foot, themselves also one day departed from life. Heraclitus, after many speculations about the fire which should consume the Universe, was waterlogged by dropsy, poulticed himself with cow-dung and died. Vermin killed Democritus; another kind of vermin Socrates. What is the moral? You went on board, you set sail, you have made the port. Step ashore: if to a second life, nothing is void of gods, not even in that other world; but if to unconsciousness, you will cease to suffer pains and pleasures and to be the servant of an earthly vessel as far inferior as that which does it service is superior; for the one is mind and deity, the other clay and gore.
