Letting go all else, cling to the following few truths. 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. This mortal life is a little thing, lived in a little corner of the earth; and little, too, is the longest fame to come - dependent as it is on a succession of fast-perishing little men who have no knowledge even of their own selves, much less of one long dead and gone.

The best way of avenging thyself is not to become like the wrong-doer.

Death, like birth, is a secret of Nature.

And thou wilt give thyself relief, if thou doest every act of thy life as if it were the last.

From Apollonius I learned freedom of will and undeviating steadiness of purpose; and to look to nothing else, not even for a moment, except to reason; and to be always the same, in sharp pains, on the occasion of the loss of a child, and in long illness.

Be not as one that hath ten thousand years to live; death is nigh at hand: while thou livest, while thou hast time, be good.

The things you think about determine the quality of your mind. Your soul takes on the color of your thoughts.
