35. Everything is only for a day, both that which remembers and that
which is remembered.

36. Observe constantly that all things take place by change, and accustom
thyself to consider that the nature of the universe loves nothing so much
as to change the things which are and to make new things like them. For
everything that exists is in a manner the seed of that which will be. But
thou art thinking only of seeds which are cast into the earth or into a
womb: but this is a very vulgar notion.

37. Thou wilt soon die, and thou art not yet simple, nor free from
perturbations, nor without suspicion of being hurt by external things,
nor kindly disposed towards all; nor dost thou yet place wisdom only in
acting justly.

38. Examine men's ruling principles, even those of the wise, what kind of
things they avoid, and what kind they pursue.

39. What is evil to thee does not subsist in the ruling principle of
another; nor yet in any turning and mutation of thy corporeal covering.
Where is it then? It is in that part of thee in which subsists the power
of forming opinions about evils. Let this power then not form [such]
opinions, and all is well. And if that which is nearest to it, the poor
body, is cut, burnt, filled with matter and rottenness, nevertheless let
the part which forms opinions about these things be quiet; that is, let
it judge that nothing is either bad or good which can happen equally to
the bad man and the good. For that which happens equally to him who lives
contrary to nature and to him who lives according to nature, is neither
according to nature nor contrary to nature.
