Remember that such was, and is, and will be the nature of the universe, and that it is not possible that the things which come into being can come into being otherwise than they do now; and that not only men have participated in this change and transmutation, and all other living things which are on the earth, but also the things which are divine. And indeed the very four elements are changed and transmuted up and down, and earth becomes water and water becomes air, and the air again is transmuted into other things, and the same manner of transmutation takes place from above to below. If a man attempts to turn his mind towards these thoughts, and to persuade himself to accept with willingness that which is necessary, he will pass through life with complete moderation and harmony.
