That which rules within, when it is according to nature, is so affected with respect to the events which happen, that it always easily adapts itself to that which is and is presented to it. For it requires no definite material, but it moves towards its purpose, under certain conditions however; and it makes a material for itself out of that which opposes it, as fire lays hold of what falls into it, by which a small light would have been extinguished: but when the fire is strong, it soon appropriates to itself the matter which is heaped on it, and consumes it, and rises higher by means of this very material.
This then remains: Remember to retire into this little territory of thy own, and above all do not distract or strain thyself, but be free, and look at things as a man, as a human being, as a citizen, as a mortal. But among the things readiest to thy hand to which thou shalt turn, let there be these, which are two. One is that things do not touch the soul, for they are external and remain immovable; but our perturbations come only from the opinion which is within. The other is that all these things, which thou seest, change immediately and will no longer be; and constantly bear in mind how many of these changes thou hast already witnessed. The universe is transformation: life is opinion.
Within ten days thou wilt seem a god to those to whom thou art now a beast and an ape, if thou wilt return to thy principles and the worship of reason.
The universal nature out of the universal substance, as if it were wax, now moulds a horse, and when it has broken this up, it uses the material for a tree, then for a man, then for something else; and each of these things subsists for a very short time. But it is no hardship for the vessel to be broken up, just as there was none in its being fastened together.
That which has died falls not out of the universe. If it stays here, it also changes here, and is dissolved into its proper parts, which are elements of the universe and of thyself. And these too change, and they murmur not.
A cucumber is bitter.- Throw it away.- There are briars in the road.- Turn aside from them.- This is enough. Do not add, And why were such things made in the world? For thou wilt be ridiculed by a man who is acquainted with nature, as thou wouldst be ridiculed by a carpenter and shoemaker if thou didst find fault because thou seest in their workshop shavings and cuttings from the things which they make. And yet they have places into which they can throw these shavings and cuttings, and the universal nature has no external space; but the wondrous part of her art is that though she has circumscribed herself, everything within her which appears to decay and to grow old and to be useless she changes into herself, and again makes other new things from these very same, so that she requires neither substance from without nor wants a place into which she may cast that which decays. She is content then with her own space, and her own matter and her own art.
Consider whence each thing is come, and of what it consists, and into what it changes, and what kind of a thing it will be when it has changed, and that it will sustain no harm.
