Meditations of Marcus Aurelius Book VI
The substance of the universe is obedient and compliant; and the reason which governs it has in itself no cause for doing evil, for it has no malice, nor does it do evil to anything, nor is anything harmed by it. But all things are made and perfected according to this reason.
Let it make no difference to thee whether thou art cold or warm, if thou art doing thy duty; and whether thou art drowsy or satisfied with sleep; and whether ill-spoken of or praised; and whether dying or doing something else. For it is one of the acts of life, this act by which we die: it is sufficient then in this act also to do well what we have in hand.
Look within. Let neither the peculiar quality of anything nor its value escape thee.
All existing things soon change, and they will either be reduced to vapour, if indeed all substance is one, or they will be dispersed.
The reason which governs knows what its own disposition is, and what it does, and on what material it works.
The best way of avenging thyself is not to become like the wrong doer.
Take pleasure in one thing and rest in it, in passing from one social act to another social act, thinking of God.
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.
In conformity to the nature of the universe every single thing is accomplished, for certainly it is not in conformity to any other nature that each thing is accomplished, either a nature which externally comprehends this, or a nature which is comprehended within this nature, or a nature external and independent of this.
The universe is either a confusion, and a mutual involution of things, and a dispersion; or it is unity and order and providence. If then it is the former, why do I desire to tarry in a fortuitous combination of things and such a disorder? And why do I care about anything else than how I shall at last become earth? And why am I disturbed, for the dispersion of my elements will happen whatever I do. But if the other supposition is true, I venerate, and I am firm, and I trust in him who governs.
