The constant recollection of death is the test of human conduct.

The impediment to action advances action. What stands in the way becomes the way.

That which makes the man no worse than he was makes his life no worse: it has no power to harm, without or within.

Why should a man have any apprehension about the change and dissolution of all the elements? For it is according to nature, and nothing is evil which is according to nature.

Remember that man lives only in the present, in this fleeting instant; all the rest of his life is either past and gone, or not yet revealed.

Unhappy am I because this has happened to me.- Not so, but happy am I, though this has happened to me, because I continue free from pain, neither crushed by the present nor fearing the future.

All things are in the act of change; thou thyself in ceaseless transformation and partial decay, and the whole universe with thee.
