A lifetime of self-inquiry into conflict, strategy, and human performance.

Many martial arts teach technique. Few directly address kokoro—the mental attitude of the warrior.

That is the focus of this year’s Ittō Tenshin-ryū Taikai.

Kokoro is critical to one’s ability to act in the moment and is equally important across all domains of life.

If you are curious about this subject, or about how the Ittō Tenshin-ryū shares this concept with its deshi, join us in Albuquerque this October.

"For those lacking direct experience, confidence in the authenticity of the teachings often depends upon the credibility of the historical record. For those familiar with conflict, however, the decisive criterion is whether the wisdom transmitted through the scrolls withstands practical testing."

"For those lacking direct experience, confidence in the authenticity of the teachings often depends upon the credibility of the historical record. For those familiar with conflict, however, the decisive criterion is whether the wisdom transmitted through the scrolls withstands practical testing."

This coming Tuesday will be the final session of our study of the Gorin no Sho, which began on January 9, 2024.

The group convened twice each month. Although sessions were scheduled for 75 minutes, they frequently extended to 90 minutes or longer as our exploration deepened.

From the outset, this study was not an exercise in historical analysis, nor was it simply an examination of the text at face value. The general principles Musashi sought to communicate lie beneath the surface of his words and must be extracted through informed examination. Texts of this nature constitute the bones of a tradition; the flesh that gives those bones substance and meaning is supplied through oral transmission. Our objective was to identify these underlying principles, assess their validity in relation to our own training, and, where appropriate, internalize them.

This endeavor is inherently challenging.

The original manuscript of the Gorin no Sho has never been found. Existing translations and editions are derived from handwritten copies and successive copies of those copies, resulting in variations and inconsistencies across the surviving texts. Much of what is widely accepted about Musashi likewise rests upon carefully researched inference rather than historically verifiable fact. These conditions complicate any effort to determine precisely what Musashi intended and contribute to the persistent lack of clarity surrounding his teachings.

These textual uncertainties, however, do not alone explain the continuing demand for translations, commentaries, lectures, documentaries, and other analyses of the Gorin no Sho. The principal force sustaining that demand is the persistent sense that the essential wisdom of the work has not yet been fully revealed. In this respect, the market resembles that surrounding the Kennedy assassination: people continue searching because no existing account appears to resolve the matter completely. Each new work offers the possibility of disclosing another missing fragment, and thus the search—and the consumption of information—continues.

Yet the accumulation of information does not ensure the recognition of truth.

For those lacking direct experience, confidence in the authenticity of the teachings often depends upon the credibility of the historical record. For those familiar with conflict, however, the decisive criterion is whether the wisdom transmitted through the scrolls withstands practical testing.

Recognizing the validity of that wisdom requires both direct experience and a nuanced understanding of Japanese culture and swordsmanship. Without this foundation, extracting the essential teachings of the Gorin no Sho is exceptionally difficult.

The text is accessible to all. Its deeper meaning is not.

I extend my sincere gratitude to those who remained committed throughout this two-year, seven-month study. I have learned a great deal through this examination of Musashi’s teachings and hope that each of you derived similar value from the undertaking.

If there is a particular work on strategy or Japanese swordsmanship that you would like to see examined in this format, please inform me. I am currently considering possible subjects for our next course.

🔊 Sound on. Ms. Natasha Nakhshin speaks to the power and value of training in Ittō Tenshin-ryū Kenjutsu—and how the lessons forged beneath the sword extend far beyond the dōjō.

Recently, someone asked me, “What is the purpose of your retreat?” “I am retreating from nothing,” I responded. “I am going to engage fully with life!”

Zazen is an indispensable exercise within our traditions. It affords the practitioner an opportunity for direct realization.

The martial traditions of Japan have long recognized the value of leaving familiar surroundings and entering periods of disciplined training in solitude. The mountains were not simply places of seclusion. They provided conditions in which familiar patterns could fall away, allowing the practitioner to encounter existence more directly.

This practice is not unique to the samurai. Periods of seclusion amid the rawness of nature appear in religious and spiritual traditions throughout the world.

This September, I will enter a monastery in the mountains to undertake forty days of intensive meditative exercise, solitude, silence, and martial training.

Recently, someone asked me, “What is the purpose of your retreat?”

“I am retreating from nothing,” I responded. “I am going to engage fully with life!”

In our traditions, when a deshi receives a certificate in recognition of what they have done, and perhaps what they are capable of being, they are guided to observe it, celebrate the accomplishment, and then place it in their sock drawer.

The Way and The Power – Podcast Launch Announcement - Episode 1: Conflict & Struggle

The Way and The Power Podcast explores conflict, strategy, and performance through the lens of three martial traditions originating from Japan. This episode sets the stage: our mission, the host’s role, and key principles to guide your path. Then, we dive deep into the nature of conflict—the universal force shaping every life. Struggle is inevitable. The critical question we all face is this: how do we live balanced, whole, and fulfilling lives amid the turmoil of existence?

Ittō Tenshin-ryū®

The 2024 Ittō Tenshin-ryū Taikai, a significant event within our tradition, concluded on Sunday evening. Additionally, we celebrated the founding of the Great Falls Budokan by Rajguru Sensei 50 years ago.

The theme of the taikai was "Setsunateki" (刹那的), a concept that beautifully encapsulates impermanence and the present moment. In keeping with the theme, there will be no after-action report.

The purpose of the Ittō Tenshin-ryū remains true to its inception: to enhance life through the empowerment of its deshi.

While some outside our tradition claim lineage to the Ittō Tenshin-ryū, this is impossible. The transmission of this tradition requires access to its "living example" and occurs in a moment.
