Meditation 9.24-26
Marcus AureliusMeditationsBook 9.24
24. Children's fits of temper and dolls and 'spirits carrying dead bodies', so that the story of the visit to the abode of Death strikes one more vividly.
25. Penetrate to the individuality of the cause and separating it from the matter, look into it; next isolate the time which at longest this individuality can by its nature subsist.
26. You endure a myriad troubles because you are not content with your governing self doing the kind of things it was formed to do. But enough.
