The Meditations of Marcus Commodus

When Marcus was not out fighting in the field, he took time out to write a sort of philosophical diary as part of his daily quest to crack the underlying code of existence. When you remove Marcus from the equation and read it yourself, what you get is a series of injunctions reminding you how to live virtuously. Also helping the text to remain eternally relevant is that Marcus was basically writing a series of reminders for himself as he strove to live virtiously.
