Epictetus emphasizes the importance of understanding ownership in a philosophical sense. He argues that if one mistakes what is inherently servile or external to them as being their own, they will inevitably suffer, feeling trapped and resentful towards the world. This intrinsic misunderstanding leads to unhappiness and blame directed not only at others but also at the divine. Thus, the core concept is to recognize and accept what truly belongs to oneself and to let go of the attachments to what does not.

When individuals adopt a mindset that only considers what is genuinely their own as belonging to them, they free themselves from external pressures and influences. This perspective fosters a sense of autonomy and peace, as one realizes that they cannot be coerced or wronged in ways that matter. By relinquishing the need to possess or control things outside themselves, they become invulnerable to harm, finding themselves at peace and free from animosity. Ultimately, this philosophical approach advocates for personal responsibility and mental clarity, allowing for a fulfilled and tranquil life.
