Constantly regard the universe as one living being, having one substance and one soul; and observe how all things have reference to one perception, the perception of this one living being; and how all things act with one movement; and how all things are the cooperating causes of all things which exist; observe too the continuous spinning of the thread and the contexture of the web.
Soon, very soon, thou wilt be ashes, or a skeleton, and either a name or not even a name; but name is sound and echo. And the things which are much valued in life are empty and rotten and trifling, and like little dogs biting one another, and little children quarrelling, laughing, and then straightway weeping. But fidelity and modesty and justice and truth are fled Up to Olympus from the wide-spread earth. What then is there which still detains thee here? If the objects of sense are easily changed and never stand still, and the organs of perception are dull and easily receive false impressions; and the poor soul itself is an exhalation from blood. But to have good repute amidst such a world as this is an empty thing. Why then dost thou not wait in tranquility for thy end, whether it is extinction or removal to another state? And until that time comes, what is sufficient? Why, what else than to venerate the gods and bless them, and to do good to men, and to practise tolerance and self-restraint; but as to everything which is beyond the limits of the poor flesh and breath, to remember that this is neither thine nor in thy power.
The ruling principle is that which rouses and turns itself, and while it makes itself such as it is and such as it wills to be, it also makes everything which happens appear to itself to be such as it wills.
Return to thy sober senses and call thyself back; and when thou hast roused thyself from sleep and hast perceived that they were only dreams which troubled thee, now in thy waking hours look at these (the things about thee) as thou didst look at those (the dreams).
To the jaundiced honey tastes bitter, and to those bitten by mad dogs water causes fear; and to little children the ball is a fine thing. Why then am I angry? Dost thou think that a false opinion has less power than the bile in the jaundiced or the poison in him who is bitten by a mad dog?
A man deposits seed in a womb and goes away, and then another cause takes it, and labours on it and makes a child. What a thing from such a material! Again, the child passes food down through the throat, and then another cause takes it and makes perception and motion, and in fine life and strength and other things; how many and how strange I Observe then the things which are produced in such a hidden way, and see the power just as we see the power which carries things downwards and upwards, not with the eyes, but still no less plainly.
