Withdraw to the untroubled quietude deep within the soul, and refresh yourself.

No form of nature is inferior to art; for the arts merely imitate natural forms.

A man does not sin by commission only, but often by omission.

Mark how fleeting and paltry is the estate of man - yesterday in embryo, tomorrow a mummy or ashes. So for the hairsbreadth of time assigned to thee, live rationally, and part with life cheerfully, as drops the ripe olive, extolling the season that bore it and the tree that matured it.

People who labor all their lives but have no purpose to direct every thought and impulse toward are wasting their time-even when hard at work.
