Letters 102.25

You may take away no more than you brought in; what is more, you must throw away the major portion of that which you brought with you into life: you will be stripped of the very skin which covers you—that which has been your last protection; you will be stripped of the flesh, and lose the blood which is suffused and circulated through your body; you will be stripped of bones and sinews, the framework of these transitory and feeble parts.

Seneca, Letters to Lucilius 102.25, translated by Richard Mott Gummere
