TO live happily is an inward power of the soul, when she is affected with indifference, towards those things that are by their nature indifferent.
MARCUS AURELIUS. MEDITATIONS. Book xi. 15.
IT is in thy power absolutely to exclude all manner of conceit and opinion, as concerning this matter; and by the same means, to exclude all grief and joy from thy soul. For as for the things and objects themselves, they of themselves have no such power, whereby to beget and force upon us any opinion at all.
MARCUS AURELIUS. MEDITATIONS. Book vi. 47.
DOST thou grieve that thou dost weigh but so many pounds, and not 300 rather? Just as much reason hast thou to grieve that thou must live but so many years, and not longer. For as for bulk and substance thou dost content thyself with that proportion of it that is allotted unto thee, so shouldst thou for time.
