Train Your Mind
Principle 28 from the Enchiridion
Epictetus asks why we guard our body more carefully than our mind, reminding us not to let insults or criticism control our inner state.
Original Passage
If a person gave your body to any stranger he met on his way, you would certainly be angry. And do you feel no shame in handing over your own mind to be confused and mystified by anyone who happens to verbally attack you?
Modern Interpretation
Epictetus asks a sharp question: why do we guard our body more than our mind? Most people would never allow a stranger to physically control them, yet they let random criticism or insults dictate their mood for hours.
Stoicism treats this as a loss of dignity. Your mind is your highest responsibility. If anyone can provoke, flatter, or frighten you into confusion, then you have given away your inner authority.
The practice is mental boundaries. Hear words, evaluate them, and choose your response. Useful criticism can be accepted. Empty attacks can be dropped. Either way, your mind remains yours.
This principle is not emotional numbness. It is disciplined ownership of attention and interpretation.
In Practice Today
You receive a harsh comment from someone you barely know, and you replay it all day. Work quality drops and your energy collapses.
A Stoic response is to pause and ask: "Am I handing this person control of my mind?" You extract any useful point, discard the rest, and return to your priorities.
You protect your inner space the way you would protect your home.

Whose opinion are you currently allowing to occupy your mind more than your own reason deserves?
