MARCUS AURELIUS:

When a man finds his sole good in that which the appointed hour brings him; when he cares not if his actions be many or few, so they accord with strict reason; when it matters nought to him whether his glimpse of this world be long or fleeting -- not death itself can be a thing of terror to him.

...

Death: a release from impressions of sense, from twitching of appetite, from excursions of thought, and service to the flesh.
