Summary
This quote emphasizes the power and importance of mental strength and self-control. It suggests that being ruled by one's mind, or having control over one's thoughts and emotions, grants an individual authority and mastery over their own life, making them the "king" of their own destiny. On the other hand, being dominated by physical desires and impulses renders a person submissive and controlled, making them a "slave" to their bodily needs. It highlights the idea that true freedom and empowerment come from prioritizing the intellect and making conscious decisions, rather than succumbing to momentary temptations or urges.
