Put Your Heart and Soul into Consistent Martial Training

Mats Hjelm "Bujinkan Toryu"November 11, 2024

From 武神館兜龍 Bujinkan Toryu by Mats Hjelm "Bujinkan Toryu"

My master often spoke of his teacher’s belief in the importance of consistent martial training. He shared stories of his teacher’s journey, how he devoted himself to a level of practice that went beyond physical skill to shape his spirit and mind. Much like traditional Kabuki actors who sustain their roles off-stage, his master insisted that training be an integral, daily practice. As martial artists, my master’s teacher would say, we must embrace Bufu Ikkan, or “consistent warrior living.” This was his core lesson: never give up. Keep going.

Early Years: Devotion Beyond Normal Limits

Consistent Martial Training; Musha Dori

In his early days of training, my teacher was determined to achieve greatness. He threw himself into physical practice three times harder than other students. He put in three times the mental focus and invested three times the resources to gain the wisdom he needed. Through this intense devotion, he became very strong.

But as he grew in strength, he felt a strange weakness arise. This new vulnerability troubled him deeply, and despite his efforts, he couldn’t identify its cause. Yet, he trusted his training and continued, confident that the martial tradition itself would bring clarity.

“The way of the warrior is the resolute acceptance of death.” — Miyamoto Musashi

The Challenge of Illness: A Test of True Strength

Consistent Martial Training; Sannindori

One day, my master faced a powerful enemy—illness. It left him weak, even struggling to stand. At times, he couldn’t see. For five years, he endured this trial, and the demands of his illness made him feel that giving up might be easier than living. It was here that he discovered his past strength had been an illusion. His power depended on his health; as his health declined, so did his strength.

True strength, he learned, must go beyond physical condition. Strength that fades in hardship is merely temporary. So, even in his weakened state, he continued training however he could. Slowly, he began to regain his health.

“One must polish one’s heart daily, like a sword.” — Yagyū Munenori

Adapting Training to Life’s Changes

consistent martial training; Kage no Kamae

Looking back, he realized that consistent martial training had carried him through his years of illness. He had adapted his training to fit his limited energy and discovered that training must evolve with life’s stages. He learned that young warriors train intensely, while older ones need a more focused approach. Even illness has its own form of training, and facing death is the final training of a warrior.

True strength, my master would say, comes from matching our training to our current reality. Training adapted to life stages becomes a source of lasting, resilient strength.

“The wise warrior avoids the battle; when he must fight, he fights only to win.” — Tsunetomo Yamamoto

Rethinking Strength

After years of illness, my master understood that true power goes beyond the physical. It doesn’t depend on speed or brute force. Instead, he came to value “natural and fitting technique”—a strength that flows with nature and conditions, not against them. In doing so, he found a higher, adaptive strength beyond what traditional martial arts schools might teach.

Pushing Through Difficult Periods

My teacher knew martial artists often face times when techniques seem impossible, and training becomes frustrating. He taught that these periods of struggle are crucial. Like a snake shedding its skin, we too must experience discomfort to grow. This “molting period,” as he called it, can tempt martial artists to look elsewhere for easier techniques. Yet, he advised against these distractions, saying they’re a temporary escape, not a solution.

However, he also cautioned that not everyone is suited to master every art. Sometimes, a goal may simply not fit, and one may need to reevaluate their path. But for those who feel a true calling, consistent martial training will provide growth beyond these challenging phases.

The Power of Sincere Commitment

My master always taught that true training requires a pure, sincere heart, not just an accumulation of techniques. Training without self-awareness produces only a scholar, a “walking catalog of techniques” without heart. Only those who commit deeply and consistently will discover the true essence of martial arts and gain the lasting strength that lies beyond technique.

Passion as the Source of Training Motivation

Mats Hjelm "Bujinkan Toryu"November 4, 2024

From 武神館兜龍 Bujinkan Toryu by Mats Hjelm "Bujinkan Toryu"

In martial arts, passion as the Source of Training Motivation. This “heat of passion” transforms training from a mechanical repetition of techniques into a journey toward mastery. Without this energy, your training can stagnate, failing to reach the true essence of the art. Just as iron loses its potential when it cools before being fully forged, a martial artist loses purpose without the fire of passion.

Heat and Spirit in the Training

Passion as the Source

In Japanese, “heat” (netsu) connects to numerous words that reflect the intensity required to master any art form. Nesshin (熱心) represents “enthusiasm” or “spirit fueled by heat”; nekkyo (熱狂) signifies “excitement”; and netsuretsu (熱烈) translates as “passionate.” These words reveal how essential fiery intensity is when shaping or transforming anything, including a martial artist. Each training session becomes an opportunity to cultivate this heat, constantly working on weaknesses and enhancing strengths. The cycle of passion and perseverance propels personal growth.

“The path is simple; it is the heart that makes it difficult.” — Anonymous samurai proverb.

Mastery Through Passion: Attaining the Gokui

Source of Training Motivation

Martial arts contain a concept known as the Gokui (極意), which translates as “mastering the secrets.” These secrets are often found in ancient scrolls, written in language that obscures their meaning to prevent uninitiated readers from accessing them. They may seem simple, but understanding how to apply these teachings requires time and experience. For example, the formula for calculating a circle’s circumference (C = πD) seems straightforward, yet immense effort and insight were needed to discover it. Similarly, in martial arts, knowing techniques or kata alone isn’t enough. The secrets lie in how these insights connect and transform practice into understanding.

“The man who has attained mastery does not hold on to fixed forms.” — Takuan Sōhō.

Levels of Mastery in Martial Lineages

Source of Training Motivation

In authentic martial traditions, growth continues beyond any predefined endpoint. My teachers teacher, Toshitsugu Takamatsu, imparted four levels of mastery: Shoden (初伝), “beginning transmission”; Chuden (中伝), “middle transmission”; Okuden (奥伝), “inner transmission”; and finally Kaiden (皆伝), or “total transmission.” These levels guide students from basic skill to complete understanding of the lineage’s training method. From there, the practitioner must pursue personal mastery.

Each level serves as a foundation for deeper insights and techniques, yet mastery remains an ongoing journey.

“Mastery is not a goal but a journey, a path never fully traveled.” — Yagyū Munenori.

Training Without Limit: Beyond Techniques

People often ask how many techniques a martial artist knows, as if mastery were a checklist. But in living martial traditions, it’s not the number of techniques that matters—it’s how passion guides you to apply and internalize them. 武風一貫 Bufu Ikkan, or consistent and earnest training, surpasses the memorization of techniques alone. Memorization doesn’t lead to mastery; only a deep-rooted passion can transform knowledge into skill and skill into enlightenment.

Footnotes

  1. Netsu (熱) – Kanji for “heat,” representing the essential force behind enthusiasm, ardor, and passion.
  2. Nesshin (熱心) – Combination of netsu (熱, heat) and shin (心, spirit or heart), meaning “enthusiasm.”
  3. Gokui (極意) – Means “mastering the secrets”; goku (極) for “extreme” and i (意) for “intent or meaning.”
  4. Bufu Ikkan (武風一貫) – Means “consistent observation of martial wind or tradition.”
  5. Shoden (初伝) – “Beginning transmission,” with sho (初) meaning “first” or “beginning,” and den (伝) meaning “transmission.”

Solo Training, don’t forget it – A Vital Part of Martial Arts Mastery

Mats Hjelm "Bujinkan Toryu"September 19, 2024

From 武神館兜龍 Bujinkan Toryu by Mats Hjelm "Bujinkan Toryu"

This text about don’t forget about solo training summarizes a chapter from Masaaki Hatsumi’s “Hiden Togakure Ryū Ninpō.” It emphasizes the importance of solo training in martial arts, drawing on Hatsumi’s experiences in nature.

Don’t Forget Solo Training – A Vital Part of Martial Arts Mastery

In modern martial arts, practitioners often neglect solo training, focusing solely on group classes and teacher-led instruction. However, the author of “Hiden Togakure Ryu Ninpo” highlights the importance of solitary practice, drawing on personal experiences from the Japanese warrior tradition. Early training involved long, isolated periods in the mountains, where nature became the author’s sparring partner.

Trees, branches, and roots replaced human opponents, offering unique challenges for strikes, throws, and sweeps. This form of training developed not only physical skills but also mental clarity, awareness, and the ability to read the environment. Including the animals inhabiting the forest. Through this process, the practitioner learned valuable lessons about both the martial arts and life itself.

Hicho Kaiten as solo training

Solo Training vs. Group Instruction

While an excellent teacher is a significant asset. The author argues that martial arts students often encounter teachers who lack the depth of knowledge they claim to possess. Relying entirely on such instruction can lead to becoming a “puppet,” performing techniques without genuine understanding. In contrast, solo training forces the individual to develop their skills through personal trial and error. Leading to a deeper, more authentic mastery. The freedom to explore techniques independently can foster creativity and self-discovery that structured classes may stifle.

The Role of the Teacher

Do as the Sensei say in your solo training

Interestingly, even when a skilled teacher is available, students may still choose to train independently. The author, as a martial arts instructor, has observed that some students prefer their methods. Even when they may be misguided.

In such cases, rather than forcing the student to adhere strictly to the teacher’s lessons. The author allows them to follow their path. This hands-off approach can sometimes lead the student to unexpected learning moments. Much like an apprentice who absorbs knowledge through prolonged exposure rather than direct instruction.

The Balance Between Discipline and Freedom

The key to effective martial arts training lies in balancing discipline with freedom. Overloading a student with too many lessons can be counterproductive, leading to burnout or confusion. The author believes in allowing students to progress at their own pace. Offering advanced techniques only to those who are ready to handle them. True martial arts mastery isn’t about memorizing countless moves or self-defense tricks—it’s about cultivating awareness, mental clarity, and readiness.

Solo Training and Broader Learning

The author encourages martial arts students, especially young ones, to embrace solo training as a part of their personal growth. Martial arts is not just about physical combat but a holistic discipline that includes philosophy, psychology, history, and even subjects like physics and chemistry. By being fascinated with martial arts, students can find motivation in every area of life. Turning each experience into an opportunity for learning and self-improvement.

The Philosophy of Continuous Learning

solo training flying through the air

Ultimately, martial arts is a lifelong journey. The phrase “Jinsei hitori geiko nari” (“Life is made up of solo training”) encapsulates this philosophy. Every moment of life, whether in the dojo or outside, offers lessons if one remains open and committed to self-examination. Solo training not only builds martial arts skills but also fosters personal growth. Leading to a life rich in discoveries and insights.

In conclusion, solo training should not be forgotten. It is a powerful tool for developing both the body and the mind. Enabling martial artists to achieve true mastery and personal fulfillment.

Hiden Togakure Ryu Ninpo (Back Cover)

In my historical novels, many ninjas make appearances. As a result, they are often called “ninjutsu novels,” but I am not writing about ninjutsu, I am writing about ninjas. It is rare for ninjas to surface in the mainstream history of the Warring States period. However, in reality, many events were shaped by the actions of ninjas.

Yet, these “shinobi” who lived in the night and moved in the shadows were often unrecognized technicians. They constantly walked a tightrope and had to survive in an environment filled with contempt. The techniques developed and passed down by these ninjas are a unique, blood-earned art form in the world. The term “shinobi” cannot be accurately translated into any other language, just as it is difficult for foreigners to fully comprehend the true meaning of bushidō.

Hatsumi-kun, a modern-day ninja, is the legitimate successor to the techniques of the former ninjas and is famous today for his unparalleled skill. He is highly respected in his community as a skilled bonesetter, and his character and wisdom are equally admirable.

Hatsumi teaches his disciples that the true meaning of being shinobi lies in enduring hardship, and that only by overcoming the trials and tribulations of life can one develop their character, thereby perfecting their techniques.

In today’s chaotic human world, Hatsumi-kun, who truly understands the meaning of endurance and perseverance, has written this book. It not only explains the true path of the ninja but will surely serve as a guide for living. This is the reason I confidently recommend it to the public.

四習界 Shishūkai: Four Worlds of Mastery

adminMay 8, 2024

From 武神館兜龍 Bujinkan Toryu by admin

Introduction to the Four Worlds of Mastery

The Four Worlds of Mastery


In the disciplined and deeply philosophical world of Bujinkan, the journey from novice to master involves more than physical prowess. Additionally, it encompasses profound personal growth. The “Four Worlds of Mastery” guide this path, mirroring the traditional martial arts progression of Shu-Ha-Ri. It also highlights common cognitive biases, such as the Dunning-Kruger effect. Understanding these stages offers practitioners a roadmap for development that extends beyond physical skills to encompass mental and spiritual maturation.

Incompetent Awareness

“Incompetent awareness” marks the initial stage in a martial artist’s journey. Here, you recognize your novice status and embrace the humility that comes with starting anew. Like the Shu phase in Shu-Ha-Ri, this stage is about strict adherence to form and technique, absorbing knowledge like a sponge. You learn to perform kata (forms) and techniques exactly as taught, respecting the wisdom and effectiveness of established methods. This phase is foundational, as it builds the discipline and basic skills necessary for advanced exploration.

Incompetent Unawareness

As skills and confidence grow, practitioners often enter the stage of “incompetent unawareness,” where the Dunning-Kruger effect becomes most apparent. Here, you might feel more competent than you actually are due to initial successes and basic fluency in techniques. This stage is a critical juncture and reflects the early transition from Shu to Ha, where the danger lies in becoming complacent with one’s perceived level of skill.

You must remain vigilant to continue pushing boundaries and seeking deeper understanding instead of settling for superficial knowledge. This stage urges practitioners to recognize the breadth of what they don’t know and to approach training with a critical eye.

Competent Awareness

Transitioning into “competent awareness,” practitioners begin to deeply integrate their skills and knowledge. This stage aligns with the Ha phase of Shu-Ha-Ri, characterized by experimentation and adaptation. You understand the principles behind each technique and start to experiment with variations, adapting what you’ve learned to suit different situations and personal style.

This is a period of reflection and critical thinking, where you assess your abilities realistically and work on refining your techniques. Here, the practitioner is skilled and knowledgeable yet remains acutely aware of the limitations and gaps in their expertise.

Competent and Unaware

The final stage, “competent and unaware,” is where true mastery begins to shine. This stage mirrors the Ri phase, where practitioners execute techniques with natural ease and deep-rooted skill, making them appear instinctual.

At this level, the mind no longer consciously dictates actions; the body responds to threats and opportunities with a fluidity and grace that seem almost preternatural. This is the stage where practice transcends physical action and becomes a form of moving meditation, embodying the essence of Bujinkan in every motion.

Overwhelming Spirit

In Shinden Shura Roppō Takamatsu Sensei wrote about this experience.

There’s an interesting story related to this. When I was at Toda Shinryuken Sensei’s dojo, a martial artist from the 関口流 Sekiguchi-ryu came for a challenge match.

At that time, it was customary for younger, skilled practitioners to sit at the lower end, while older, less capable ones took the higher seats. Among us was a man, around 37 or 38, with an imposing physique but a scarred face, possibly from burns, which made him look fearsome. However, his skill was limited, and he loved to compete despite often losing.

That day, he boldly took the highest seat, and when the match began, he insisted on going first. Everyone tried to dissuade him, knowing he would lose, but he wouldn’t listen. So, he went out, exchanged formalities with the opponent, and as they bowed and separated, he suddenly widened his scarred eyes, contorted his face into a terrifying expression, and with a thunderous shout and stomp, he startled the Sekiguchi-ryu opponent.

The opponent, terrified, jumped back and conceded the match. When Toda Sensei asked the Sekiguchi-ryu practitioner why he gave up, he confessed that he was scared and thought he would be facing a weaker opponent from the lower seats. This instance shows how a mental defeat can occur even before the physical match. In martial arts, one must maintain a constant, unshaken spirit, not startled or intimidated by external changes. The true value of martial arts lies in cultivating this unflinching spirit.
Excerpt from Shinden Shura Roppō written by Takamatsu Sensei in 1966

In what category would you place the student of Toda Sensei? Where would you put the Sekiguchi student? I think it is an interesting story that teach us that sometimes courage is better than skills.

Integrating Shu-Ha-Ri and Dunning-Kruger into Bujinkan Training

Integrating the understanding of Shu-Ha-Ri, traditionally viewed as a 30-year progression, along with the awareness of cognitive biases like the Dunning-Kruger effect, is crucial for holistic development in Bujinkan training.

Recognizing your current position within these stages is essential for maintaining a realistic assessment of your skills and encouraging ongoing improvement. Furthermore, the Dunning-Kruger effect serves as a vital reminder to stay humble and vigilant. It urges you to continuously question your level of skill and actively seek feedback from more experienced practitioners.

Practical Applications and Training Advice

To navigate these stages effectively, consider the following practical steps:

  • Seek Continuous Feedback: Regularly seek out feedback from instructors and peers to gain an accurate understanding of your skill level.
  • Engage in Deliberate Practice: Focus on areas of weakness and continuously challenge yourself with new learning opportunities.
  • Reflect and Journal: Maintain a training journal to reflect on lessons learned, challenges faced, and progress made.
  • Teach Others: Teaching is a powerful tool for deepening understanding and identifying gaps in one’s own knowledge.
  • Stay Open to Learning: Cultivate the mind of a three-year-old, an age marked by peak curiosity and learning. Embrace this beginner’s mindset at every stage of your expertise to continuously discover new insights and techniques.

Conclusion

Navigating the “Four Worlds of Mastery” in Bujinkan calls for a balanced mix of rigorous practice, self-assessment, and personal growth. By moving through each stage—from eager learner to master practitioner—you partake in both the physical and transformative aspects of martial arts. This process molds both mind and spirit. The journey reflects Shu-Ha-Ri’s lasting principles and provides a challenging path to mastery. Recognizing these stages and the pitfalls of the Dunning-Kruger effect equips you with essential tools for true mastery in Bujinkan.

Footnotes:

  1. Shu (守): Shu means to protect or obey. It emphasizes the importance of learning foundational techniques exactly as taught, without deviation.
  2. Ha (破): Ha means to break. In martial arts, this stage is about breaking away from traditions to explore and adapt techniques personally.
  3. Ri (離): Ri means to separate or transcend. It signifies achieving a level of skill so advanced that techniques are executed instinctively and effortlessly.
  4. Dunning-Kruger Effect: A cognitive bias wherein individuals with low ability at a task overestimate their ability, while those with high ability underestimate theirs, often due to a lack of self-awareness.

海蛍 Umi Hotaru: The Ninja’s Nighttime Guide

Mats Hjelm "Bujinkan Toryu"February 8, 2024

From 武神館兜龍 Bujinkan Toryu by Mats Hjelm "Bujinkan Toryu"

In the realm of stealth and strategy the Ninja once harnessed 海蛍 Umi Hotaru, sea-fireflies (Vargula hilgendorfii) a remarkable natural phenomenon as a nighttime guide. This essay delves into their ingenious use of these bioluminescent creatures for night operations.

The Art of Light in Darkness

The Ninja sought clear seas with sandy bottoms, ideal habitats for sea-fireflies. Using bait, they attracted and collected these luminous beings with precision. Ninjas kept them alive until needed, showcasing an exceptional understanding of nature and resourcefulness.

These creatures served as a subtle light source. They enabled ninjas to read maps and signal allies undetected by enemies. The method not only reflects their survival skills but also their innovative approach to problem-solving.

The practice of using sea-fireflies illuminates the depth of ninja ingenuity. It exemplifies their ability to blend with the natural world, turning simple organisms into tools of espionage and communication.

Below is a small segment from the Hizō no Densho from the Yasuda-ryū translated.

Regarding 海蛍 Umi Hotaru

Dark, moonless nights are best. Sea fireflies are found only in beautiful seas with sandy bottoms, up to three to five Hiro (a unit of measurement) deep. If there’s a protruding dock or similar structure, it’s especially good. Cut the heads of bonito, yellowtail, or mackerel in half, thread them, and throw them into the sea. Lift them after counting to 500 to wash off in a bucket of seawater. Put about twenty in seawater, lift and collect them one after another.

To keep them alive until the next morning, use a box that allows seawater to flow through well but doesn’t have gaps larger than 一分 one Bu (3.03 mm); otherwise, they might escape into the sand. Don’t forget this.

In the morning, separate them from fish flesh using a sieve (if separated when collected at night and placed in another box, it’s even better), lay them on a fine net, and dry them in the morning sunlight. They dry in about a quarter or half an hour; the shell becomes transparent, and only the white, opaque ones won’t glow. Bad.

– Good for use against rats, large birds, and insects (this is unclear). Oral tradition. Be careful when it rains; they can wash away and be ruined.

– If there’s no water, urine is also fine.

– Discuss the method of attachment with allies.

– To inform those coming later.

– For use on the way back. In places invisible to the enemy but visible to the infiltrator, bad places, good places (when facing the enemy outward), west, near the entrance of lavatories, from that place visible, rarely visited by people but clearly visible, inside a pond (moats are bad because they’re too wide), under eaves, under the floor, at the folding point of a ladder ascending from below, at a stone dropping point.

About 海蛍 Umi Hotaru on night paths.

– Apply at the base of trees. Even if it rains, the water sliding down the tree won’t wash it away. Heavy rainfall is bad for the base of the tree.

– If it’s raining heavily, break a branch and attach it in the direction of the path. Tie the branch above where the firefly is attached. When returning from a ninja mission, remove it. Fireflies are good.

– When water is added, they can glow for about one and a half minutes per inch and minute. Good in spring, autumn, and winter; in summer, they last for about a quarter of an hour. Good.

– High places (climbing up to attach takes time), low places are easily discovered. However, since Yasuda-ryū’s fireflies are used at night, one foot above the ground is best.

– To inform and communicate with those coming later. Use standing 1, 2, 3, horizontal 1, 2, 3, L-shaped 1, 2, 3, circle (draw thickly) 1, 2, 3, “me” 1, 2, 3, all types of combinations. Windmills are good in windy conditions – spinning fire (used in high places) is very good.

– Decide the length of the string based on the wind’s strength. No fireflies on the back.

– Attach to a tree branch. With the wind, it spins, having fireflies painted on one side only, so it appears and disappears. Do not attach within reach.

– To distract the enemy or as a sign for allies. Decide the length of the string based on the wind’s strength.

– For transport, just roll it up.

– Dark nights are preferable, but if there’s a moon, the lower, darker spots are best.

– High trees within a forest are very good. However, decide by throwing a string over them. But it should be visible from below.

This translation was done by ChatGPT and may not be 100% accurate. I suggest you go to Sean Askew’s web site and find a better translation. The whole 秘蔵の伝書 Hizō no Densho from 矢寿駄流 Yasuda-ryū is published in the end of Masaaki Hatsumi’s book 忍法大全 Ninpō Taizen.

Footnotes:

  1. 海蛍 (Umi-hotaru): Sea-firefly. “海” (umi) means sea, reflecting their habitat. “蛍” (hotaru) means firefly, indicating their bioluminescent nature.
  2. 奇麗 (Kirei): Beautiful. “奇” signifies strangeness, “麗” beauty, together highlighting the aesthetic appreciation in the ninja culture.
  3. 暗夜 (An’ya): Moonless night. “暗” means dark, “夜” night, emphasizing their preference for operations under cover of darkness.
  4. 砂地 (Sajichi): Sandy bottom. “砂” refers to sand, “地” to earth or ground, indicating the sea-firefly’s preferred habitat.
  5. 尋 (Hiro) or 広 (Hiro): It is not a standard measuring unit, it probably means pull this rope three to five times.
  6. 矢寿駄流 (Yasuda-ryū): This old Ninjutsu school did not survive to modern times, but their Densho is still held by a few researchers such as Hatsumi Sōke.

This exploration into the ninja’s use of sea-fireflies reveals a fascinating intersection of nature, strategy, and survival.
