Epitetus makes clear three pertinent ideas:
a) That it is not the event that causes the feeling, but rather our mental thoughts about the event.
b) We have power over our own reasoning and little else. We have influence over our desires and aversions. We have no power over our bodies, or instincts. We have power over our violations, most of the time. That which we have no power or influence over is non of my concern. It is; therefore, accept it.
c) It is the job of we humans to bring our desires and adversions into alinement with reason and Logos (Laws of Nature).
The typical desires may include greed (coveting the neighbours job), lust (coveting the neighbours ass), envy, jealousy, sorrow, fear, spite, petulance, and over-indulgence.
