Observe and contemplate on the hidden things of life: how a man's seed is but the beginning, it takes others to bring it to fruition. Think how food undergoes such changes to produce health and strength. See the power of these hidden things which, like the wind cannot been seen, but its effects can be.
Marcus AureliusConsider in what condition both in body and soul a man should be when he is overtaken by death; and consider the shortness of life, the boundless abyss of time past and future, the feebleness of all matter.
Marcus AureliusAs for others whose lives are not so ordered, he reminds himself constantly of the characters they exhibit daily and nightly at home and abroad, and of the sort of society they frequent; and the approval of such men, who do not even stand well in their own eyes, has no value for him.
Marcus AureliusThat which has died falls not out of the universe. If it stays here, it also changes here, and is dissolved into its proper parts, which are elements of the universe and of thyself. And these too change, and they murmur not".
Marcus Aurelius
