Neither in thy actions be sluggish nor in thy conversation without method, nor wandering in thy thoughts, nor let there be in thy soul inward contention nor external effusion, nor in life be so busy as to have no leisure.
Suppose that men kill thee, cut thee in pieces, curse thee. What then can these things do to prevent thy mind from remaining pure, wise, sober, just? For instance, if a man should stand by a limpid pure spring, and curse it, the spring never ceases sending up potable water; and if he should cast clay into it or filth, it will speedily disperse them and wash them out, and will not be at all polluted. How then shalt thou possess a perpetual fountain and not a mere well? By forming thyself hourly to freedom conjoined with contentment, simplicity and modesty.
