Let the part of thy soul which leads and governs be undisturbed by the movements in the flesh, whether of pleasure or of pain; and let it not unite with them, but let it circumscribe itself and limit those affects to their parts. But when these affects rise up to the mind by virtue of that other sympathy that naturally exists in a body which is all one, then thou must not strive to resist the sensation, for it is natural: but let not the ruling part of itself add to the sensation the opinion that it is either good or bad.
About pain: The pain which is intolerable carries us off; but that which lasts a long time is tolerable; and the mind maintains its own tranquility by retiring into itself, and the ruling faculty is not made worse. But the parts which are harmed by pain, let them, if they can, give their opinion about it.
In every pain let this thought be present, that there is no dishonour in it, nor does it make the governing intelligence worse, for it does not damage the intelligence either so far as the intelligence is rational or so far as it is social. Indeed in the case of most pains let this remark of Epicurus aid thee, that pain is neither intolerable nor everlasting, if thou bearest in mind that it has its limits, and if thou addest nothing to it in imagination: and remember this too, that we do not perceive that many things which are disagreeable to us are the same as pain, such as excessive drowsiness, and the being scorched by heat, and the having no appetite. When then thou art discontented about any of these things, say to thyself, that thou art yielding to pain.
Thou hast not leisure or ability to read. But thou hast leisure or ability to check arrogance: thou hast leisure to be superior to pleasure and pain: thou hast leisure to be superior to love of fame, and not to be vexed at stupid and ungrateful people, nay even to care for them.
Whatever man thou meetest with, immediately say to thyself: What opinions has this man about good and bad? For if with respect to pleasure and pain and the causes of each, and with respect to fame and ignominy, death and life, he has such and such opinions, it will seem nothing wonderful or strange to me, if he does such and such things; and I shall bear in mind that he is compelled to do so.
Pain is either an evil to the body- then let the body say what it thinks of it- or to the soul; but it is in the power of the soul to maintain its own serenity and tranquility, and not to think that pain is an evil. For every judgement and movement and desire and aversion is within, and no evil ascends so high.
If thou takest away thy opinion about that which appears to give thee pain, thou thyself standest in perfect security.- Who is this self?- The reason.- But I am not reason.- Be it so. Let then the reason itself not trouble itself. But if any other part of thee suffers, let it have its own opinion about itself.
Hindrance to the perceptions of sense is an evil to the animal nature. Hindrance to the movements (desires) is equally an evil to the animal nature. And something else also is equally an impediment and an evil to the constitution of plants. So then that which is a hindrance to the intelligence is an evil to the intelligent nature. Apply all these things then to thyself. Does pain or sensuous pleasure affect thee? The senses will look to that.- Has any obstacle opposed thee in thy efforts towards an object? if indeed thou wast making this effort absolutely (unconditionally, or without any reservation), certainly this obstacle is an evil to thee considered as a rational animal. But if thou takest into consideration the usual course of things, thou hast not yet been injured nor even impeded. The things however which are proper to the understanding no other man is used to impede, for neither fire, nor iron, nor tyrant, nor abuse, touches it in any way. When it has been made a sphere, it continues a sphere.
It is not fit that I should give myself pain, for I have never intentionally given pain even to another.
Either the gods have no power or they have power. If, then, they have no power, why dost thou pray to them? But if they have power, why dost thou not pray for them to give thee the faculty of not fearing any of the things which thou fearest, or of not desiring any of the things which thou desirest, or not being pained at anything, rather than pray that any of these things should not happen or happen? for certainly if they can co-operate with men, they can co-operate for these purposes. But perhaps thou wilt say, the gods have placed them in thy power. Well, then, is it not better to use what is in thy power like a free man than to desire in a slavish and abject way what is not in thy power? And who has told thee that the gods do not aid us even in the things which are in our power? Begin, then, to pray for such things, and thou wilt see. One man prays thus: How shall I be able to lie with that woman? Do thou pray thus: How shall I not desire to lie with her? Another prays thus: How shall I be released from this? Another prays: How shall I not desire to be released? Another thus: How shall I not lose my little son? Thou thus: How shall I not be afraid to lose him? In fine, turn thy prayers this way, and see what comes.
Contemplate the formative principles (forms) of things bare of their coverings; the purposes of actions; consider what pain is, what pleasure is, and death, and fame; who is to himself the cause of his uneasiness; how no man is hindered by another; that everything is opinion.
