Miyamoto Musashi was a legendary swordsman, philosopher, and strategist from 17th-century Japan. Best known for his undefeated record in duels and his book The Book of Five Rings, Musashi was more than just a warrior—he was a thinker, an artist, and a seeker of deeper truths.
Near the end of his life, Musashi wrote a brief but profound work known as Dokkōdō (The Path of Aloneness), which contains 21 principles for living a disciplined and meaningful life. These rules reflect the wisdom of a man who had devoted his life to self-mastery, detachment, and an unwavering commitment to personal growth.
Musashi’s teachings go beyond the battlefield—they offer guidance on how to navigate the struggles of life with clarity, discipline, and inner peace. Let’s explore these 21 rules and how they can still apply to modern life.
1. Accept Everything Just the Way It Is
Musashi teaches us not to resist reality. When we fight against circumstances we cannot change, we create unnecessary suffering. True strength comes from accepting life as it unfolds, without excessive attachment or resistance.
2. Do Not Seek Pleasure for Its Own Sake
While enjoyment is a part of life, chasing pleasure as the sole purpose of living leads to emptiness. Musashi believed in balance—finding joy in discipline, purpose, and self-improvement rather than indulgence.
3. Do Not Rely on Partial Feelings
Musashi warns against being controlled by fleeting emotions. Feelings are temporary and can be deceptive; making decisions based on momentary emotions can lead to regret. Instead, rely on wisdom and reason.
4. Think Lightly of Yourself and Deeply of the World
True humility comes from realizing that the world is vast, and we are just a small part of it. Musashi advises us to focus outward—learning, observing, and understanding the bigger picture rather than being absorbed in self-importance.
5. Be Detached from Desire Your Whole Life Long
Desire leads to suffering. Musashi teaches that detachment doesn’t mean not caring—it means not being enslaved by wants and cravings. By freeing ourselves from unnecessary desires, we find inner peace.
6. Do Not Regret What You Have Done
Regret is a waste of energy. Musashi encourages us to accept our past actions, learn from them, and move forward without being consumed by guilt or what-ifs. Every mistake is a lesson.
7. Never Be Jealous
Jealousy is a distraction and a sign of insecurity. Musashi reminds us that each person walks their own path—comparing ourselves to others only leads to dissatisfaction. Focus on your own growth.
8. Never Let Yourself Be Saddened by a Separation
Life is full of comings and goings. People will leave, relationships will end, and circumstances will change. Musashi teaches us to embrace impermanence and not cling to what is meant to pass.
9. Resentment and Complaint Are Appropriate Neither for Oneself nor Others
Holding onto resentment poisons the soul. Complaining solves nothing. Instead of focusing on what’s wrong, take action or accept what cannot be changed. A warrior does not dwell on grievances.
10. Do Not Let Yourself Be Guided by the Feeling of Lust or Love
While love and passion are part of life, Musashi warns against letting them cloud judgment. Emotional attachment can lead to irrational decisions and suffering. A wise person loves with awareness, not blind attachment.
11. In All Things, Have No Preferences
This doesn’t mean lacking opinions—it means not being overly attached to specific outcomes. Being adaptable and open-minded allows us to flow with life rather than fight against it.
12. Be Indifferent to Where You Live
Musashi believed that true peace comes from within, not from external conditions. Where you live does not determine your happiness—your mindset does.
13. Do Not Pursue the Taste of Good Food
Appreciate food for its nourishment, not just for pleasure. Musashi reminds us that indulgence in sensory pleasures can be a distraction from higher pursuits.
14. Do Not Hold Onto Possessions You No Longer Need
Minimalism is a key theme in Musashi’s philosophy. Material attachments weigh us down—travel light in life, both physically and mentally. Let go of what no longer serves you.
15. Do Not Act Following Customary Beliefs
Think for yourself. Just because something is widely accepted does not make it right. Musashi urges us to challenge conventional thinking and seek our own truth.
16. Do Not Collect Weapons or Practice with Weapons Beyond What Is Useful
Even as a swordsman, Musashi understood that obsession with material things—even weapons—was a distraction. Train with purpose, but do not hoard for the sake of possession.
17. Do Not Fear Death
Fear of death leads to a fear of living. Musashi embraced mortality, understanding that death is a natural part of life. By accepting it, we can live fully and fearlessly.
18. Do Not Seek to Possess Either Goods or Fiefs for Your Old Age
Planning for the future is wise, but excessive attachment to wealth or security can become a trap. Musashi believed in living with simplicity and trusting in one’s skills rather than hoarding wealth.
19. Respect Buddha and the Gods Without Counting on Their Help
Faith is valuable, but Musashi emphasizes self-reliance. Respect higher powers, but do not depend on them to solve your problems—take responsibility for your own life.
20. You May Abandon Your Own Body, But You Must Preserve Your Honor
Physical life is temporary, but your integrity and honor define your legacy. Live with principles, even in the face of difficulty. Your values are more important than your physical survival.
21. Never Stray from the Way
“The Way” refers to one’s chosen path of mastery and self-discipline. Whether in swordsmanship, art, or personal growth, Musashi advises unwavering commitment. Stay true to your purpose and never lose sight of your path.
Applying Musashi’s Wisdom to Modern Life
Musashi’s 21 rules offer a guide to living a life of discipline, detachment, and purpose. Even though they were written centuries ago, they remain strikingly relevant today:
- In a world obsessed with status and materialism, Musashi teaches us simplicity and detachment.
- In times of emotional turmoil, he reminds us to be steady and not controlled by fleeting feelings.
- In the face of fear and uncertainty, his words inspire us to live with courage and self-reliance.
By embracing these principles, we can cultivate a mindset of resilience, clarity, and inner strength—just like the great samurai himself.
