Country houses, retreats in the mountains or by the sea—­these things men seek out for themselves; and often thou, too, dost most eagerly desire such things.  But this does but betoken the greatest ignorance; for thou art able, when thou desirest, to retreat into thyself.  No otherwhere can a man find a retreat more quiet and free from care than in his own soul; and most of all, when he hath such rules of conduct that if faithfully remembered, they will give to him perfect equanimity,—­for equanimity is naught else than a mind harmoniously disciplined.  Cease not then to betake thyself to this retreat, there to refresh thyself.  Let thy rules of conduct be few and well settled; so that when thou hast thought thereon, straightway they will suffice to thoroughly purify the soul that possesses them, and to send thee back, restless no more, to the things to the which thou must return.  With what indeed art thou disquieted?  With the wickedness of men?  Meditate on the thought that men do not do evil of set purpose.  Remember also how many in the past, who, after living in enmity, suspicion, hatred, and strife one with another, now lie prone in death and are but ashes.  Fret then no more.  But perhaps thou art troubled concerning the portion decreed to thee in the Universe?  Remember this alternative:  either there is a Providence or simply matter!  Recall all the proofs that the world is, as it were, a city or a commonwealth!  But perhaps the desires of the body still torment thee?  Forget not, then, that the mind, when conscious of its real self, when self-reliant, shares not the agitations of the body, be they great or small.  Recall too all thou hast learned (and now holdest as true) concerning pleasure and pain.  But perhaps what men call Fame allures thee?  Behold how quickly all things are forgotten!  Before us, after us, the formless Void of endless ages!  How vain is human praise!  How fickle and undiscriminating those who seem to praise!  How limited the sphere of the greatest fame!  For the whole earth is but a point in space, thy dwelling-place a tiny nook therein.  How few are those who dwell therein, and what manner of men are those who will praise thee!

Therefore, forget not to retire into thine own little country place,—­thyself.  Above all, be not diverted from thy course.  Be serene, be free, contemplate all things as a man, as a lover of his kind, and of his country—­yet withal as a being born to die.  Have readiest to thy hand, above all others, these two thoughts:  one, that things cannot touch the soul; the other, that things are perpetually changing and ceasing to be.  Remember how many of these changes thou thyself hast seen!  The Universe is change.  But as thy thoughts are, so thy life shall be. (Book iv., Sec.3.)

All things that befall thee should seem to thee as natural as roses in spring or fruits in autumn:  such things, I mean, as disease, death, slander, dissimulation, and all other things which give pleasure or pain to foolish men. (Book iv., Sec.44.)
