nd trouble thyself about nothing else.

3. Everything which happens either happens in such wise as thou art
formed by nature to bear it, or as thou art not formed by nature to bear
it. If, then, it happens to thee in such way as thou art formed by
nature to bear it, do not complain, but bear it as thou art formed by
nature to bear it. But if it happens in such wise as thou art not formed
by nature to bear it, do not complain, for it will perish after it has
consumed thee. Remember, however, that thou art formed by nature to bear
everything, with respect to which it depends on thy own opinion to make
it endurable and tolerable, by thinking that it is either thy interest
or thy duty to do this.

4. If a man is mistaken, instruct him kindly and show him his error. But
if thou art not able, blame thyself, or blame not even thyself.

5. Whatever may happen to thee, it was prepared for thee from all
eternity; and the implication of causes was from eternity spinning the
thread of thy being, and of that which is incident to it (iii. 11; iv.
26).

6. Whether the universe is [a concourse of] atoms, or nature [is a
system], let this first be established, that I am a part of the whole
which is governed by nature; next, I am in a manner intimately related
to the parts which are of the same kind with myself. For remembering
this, inasmuch as I am a part, I shall be discontented with none of the
things which are assigned to me out of the whole; for nothing is
injurious to the part if it is for the advantage of the whole. For the
whole contains nothing which is not for its advantage; and all natures
indeed have this common principle, but the nature of the universe has
this principle besides, that it cannot be compelled even by any external
cause to generate anything harmful to itself. By remembering, then, that
I am a part of such a whole, I shall be content with everything that
happens. And inasmuch as I am in a manner intimately related to the
parts which are of the same kind with myself, I shall do nothing
unsocial, but I shall rather direct myself to the things which are of
the same kind with myself, and I shall turn all my efforts to the common
interest, and divert them from the contrary. Now, if these things are
done so, life must flow on happily, just as thou mayst observe that the
life of a citizen is happy, who continues a course of action which is
advantageous to his fellow-citizens, and is content with whatever the
state
