P.S.

On a side-note I would like to add my conclusions thusfar. As far as I can tell (for now anyways) the Handbook of Epictetus talks about how to be in harmony with life, what you can do to make this happen, and to embrace what isn't up to you. This "peace and harmony" with life seems oddly fammiliar. Maybe something like the Tao Te Ching by Lao-tzu which refers to balancing life and harmonizing.
