Book Review: The Ninja Mind


This review/interview has appeared on Bonzuko (aka Daily Cross-Swords)

I recently was given the honor of reviewing former colleague Kevin Casey’s new book The Ninja Mind. Enjoy the review below and the interview with Mr. Casey following.   ~Prof. Jenn


Book Review: The Ninja Mind by Kevin Casey

Martial arts centered books tend to slant in one of two directions: either the spiritual side of things (which makes many of them read like self-help books), or the physical side (which turns them into a how-to manual for instructional use). Casey manages to combine both sides in The Ninja Mind, along with a generous throughline of personal narrative. It’s difficult to define this book therefore: it’s part instruction, as he describes various exercises one can try on one’s own; part memoir, as he recounts memories of his earliest forays into the exploration of the kuji studies in his martial art; part ode to his instructor, which to be honest turns into a bit of a Stephen K. Hayes worship-fest; and part storytelling, with the ninjamindaddition of the Hanzo tale at the end of the book.

This makes for an interesting mix, for sure, and each chapter is in bite-sized chunks, so anyone who is interested in the work can digest and manage each bit thoroughly before moving on to the next. It’s also a good move on Casey’s part to focus so much on his personal journey, as especially since he’s writing about a mental, spiritual practice (not mere physical technique), it perforce can’t really be explained other than on the individual level. His personal narration puts us there with him as he describes various fears, obstacles, and the overcoming of such.

The main problem with The Ninja Mind is the near-fawning over (albeit excellent martial arts teacher) Stephen K. Hayes. It of course makes sense that one would admire one’s teacher and, in the style of memoir, describe one’s impressions of him/experiences in learning, etc. But it goes just that much too far into putting Hayes on the demigod-guru-worship-pedestal, which tends to be off-putting in the midst of such sincere recounting of personal growth.

Bottom Line: If you can get past the teacher-worship and enjoy the personal narrative, The Ninja Mind is a detailed foray into one practitioner’s journey through the depth of martial arts spirituality in practice.



MinInterview: Kevin Casey

1) what made you choose To-Shin Do in the first place? What makes you stay with it as an art?

Unlike many of my friends that had followed ninja legends since youth, I seemed to stumble across this lineage as a series of random events. However, within just a couple of months, as a brand-new white belt in 1998, I realized that there were some larger forces at work that brought me to To-Shin Do. I had been looking for a very authentic and embodied spiritual path since early childhood. By the end of college, I had explored many different spiritual traditions and found them all to be either institutionally fossilized or irresponsibly unhinged. In frustration, I gave up on being part of a community of seekers and became determined to forge my own path to inner and outer spiritual truth. Just at that moment, I found To-Shin Do, and I was amazed to see that it already embodied so much of what I was trying to define for myself.

Now I’ve moved past the validation stage of trying to determine whether the lineage is legitimate and I am worthy. I’ve had a chance to get oriented within the landscape of To-Shin Do and the massive backstory of the ninja tradition. With that framework in place, I can really explore and develop myself as an artist and a seeker. The advanced stages of ninja training are a conversation between teachers and students, helping the students evoke their own potential in the most authentic way. My teachers provide the support, experiences and wisdom to help me realize the inner vision that was a whisper in my heart from my earliest memories.

2) why did you include the Hattori Hanzo anecdote at the end of the book?

The fiction piece at the end of the story seems to polarize readers – they either immediately resonate with it, or find it strange and out of place.

I see three major ways of relating to spiritual reality. One way I call the mythical way, where we gather stories that give the emotion and energy of the spiritual lessons. The stories are usually fantastical, over-the-top, and bring the lessons vividly to life. They are usually understood not to be literally true or historical. The Hanzo fiction is an example of this.

The second way I call the rational way. This is where we study and explain spiritual experience. This is exemplified by psychological and social analysis of how spiritual experiences work and what benefits they give us. It’s very detailed and intellectual.

The third way I call the mystical way. The mystical way is an integration and transcendence of the mythical way and the rational way. It brings the observational precision and intelligence of the rational way, but it infuses our literal, living histories with spiritual significance and emotion like the mythical way. We are the heroes of our stories. This is ultimately what I would like to offer to my readers.

The difficulty is, the mystical way is hard to transmit.  Some will need a lot of explanation and data because they are rationally inclined. Others will need a lot of stories and emotion because they are mythically inclined. The Hanzo fiction is there to address that latter group.

I’ll teasingly half-share one more secret… the fiction is not entirely fiction. Fiction can be a place to record stories that are so outrageous that no one would believe they were true.

3) will there be more books addressing the other 8 kuji?

Indeed there will be. I have outlines developed for each of the other eight Kuji books, with lists of stories and examples from my life and others’. As my personal journey continues, I acquire more stories to fill in. An-Shu Hayes and I are having exciting discussions about Kuji book 2, and I have a first draft developed. I hope to submit something to my publisher next spring.

At this point, I feel I have something significant, clear and implementable to share about the first four Kuji powers (Strength, Energy, Dragon-Riding, and Healing). For Kuji five and six (Danger Sensing and Telepathy), I have great and clear stories, but not yet an organized platform for others to try it out.  For Kuji seven and beyond, I have amazing stories, but I need a great deal more research to understand them. Luckily, each book takes almost two years, so expect the Ninja Mind of Invisibility around 2029. I should have a little more information by then.

4) have you ever studied other martial arts? Spiritual arts? If so, how do they compare/contrast with To Shin Do? 

I have never been a committed long-term student of any other martial or spiritual systems.  I have done workshop

training in boxing, fencing, judo, karate, tae kwon do, muay thai, kyudo, and kung fu. I’ve stopped in at Zen centers, Shambhala training, Catholic monasteries, shamanic drumming circles, Wiccan study groups and Jewish temples. I’ve also spent a bit of time here and there with my “cousins” in other branches of the ninja tradition and in Japanese Tendai and Tibetan Buddhist lineages, without formally being a student in those organizations.

I enjoyed all of those explorations, and I found I was never tempted to leave my home in To-Shin Do. There were attributes I admired in other approaches, and because To-Shin Do is intentionally a living framework that evolves with the individual and the culture, I could incorporate those attributes into how I train and how I teach.

To-Shin Do, and its root art of ninjutsu, emphasizes adaptability. This seems to be in contrast to most tradition-oriented systems. Yes, of course, we want to leverage the wisdom and past experiences of our lineage, so in that sense there is a tradition of passed-down methods, but the real heart of the ninja tradition is an unrelenting focus on what works and a commitment to discovering that in changing conditions. As such, we study principles and concepts from history, and then seek to manifest those ideals in the most tangible, meaningful and effective way.

The result of that, when done well, is a profound sanity and capability. To-Shin Do is not immune to the organizational neuroses of every human endeavor, but our values eventually navigate us out of it, or navigate the neurotic out of To-Shin Do.

5) to the extent that you feel comfortable, express how your recent life upheavals have informed your practice as it is laid out in your book. 

This year was brutal. It was without a doubt the toughest year of my life so far, and I won’t be surprised if it stands as the toughest year of this lifetime.  I’ll tell some of my stories in Book 2.

These experiences forced me to look in the mirror long and hard. Are these practices real? Do they hold up under major crisis?

Although the practices are magical, they do not magically solve your problems. Although they increase confidence, focus, and personal power, they do not remove all suffering from life. In truth, you mostly still have to solve all your problems in fairly ordinary ways.

The difference is, with these practices, you’ll actually get around to it. A lot of the solutions in our life are obvious but difficult. Consider improving fitness, getting a better job, improving finances, or developing better relationships with loved ones. These are critical and life-impacting, and you can Google all kinds of valid advice for free. We struggle not to understand but to implement.

Sometimes we internalize that failure to implement as evidence of character flaw. We get depressed and seek escape. The truth is, though, the failure to implement is a failure of spirit, and spirit has to be developed and maintained through spiritual practice. However gnarly and unfair life can be – and I’ve recently been put in touch with a pretty intense level of it – the only solution is to pick yourself up one more time and do what is needed. You can’t do that just through hollow internal cheerleading. You need a real cultivated perspective of personal power through a set of exercises and practices.

At my worst moments this year, giving up and dying felt like a real option. My spiritual practice reminded me of why I might get up one more time. I made a real choice to survive, and that alone is empowering. I don’t have to be here, enduring this travesty. I am choosing to be here, because there is something greater that’s worth fighting for.

The fact that the ninja tradition acknowledges this dynamic – as opposed to engaging in the fantasy of an untouchable invulnerable super-being who never suffers – gives mere mortals like ourselves a real shot at heroism. When we struggle, endure, adapt, outlast and overcome, we are ninja.

Nerd Do Well: Simon Pegg, Robots, and Growing Up Nerdy


Have you ever watched an episode of Spaced, and just started longing to have a one-sided conversation with Simon Pegg? Don’t worry, this is perfectly natural, and now your prayers have been answered. Joining the much-needed introduction of autobiographies from beloved comedians, Nerd Do Well follows the story of a precocious, young boy who grows up to be the actor, writer, comedian, celebrated geek, and zombie hunter (whoops, we dropped the “zed word”) we’ve all come to know and appreciate.

If you’re suddenly wondering what inspired Simon Pegg to put his life story down on paper, it’s cool. He seems to be a bit confused about it, too. Made clear from the start, Pegg was more interested in writing a clever sci-fi/adventure narrative starring a dashing hero that is a rather impressive combination of Batman and James Bond, and solves mysteries with the help of his state-of-the-art robot butler, Canterbury.  While Nerd Do Well is an actual memoir of Simon Pegg’s life, he does manage to slip in a few chapters of this action-adventure hero by creating a parallel story arc portraying how these real-life incidents would have been handled by his alter-ego. So if you begin to get a bit tired of reading recounts of childhood influences, never fret; soon there will be robots and espionage to put you right back on the edge of your seat.

Aside from a sneak-peak into Pegg’s imaginary Batcave, Nerd Do Well shows a very intimate side of the entertainer.  From growing up in a theater-appreciating family, to using every opportunity since an early age to exert his comedic side, even into teenage romances, and embarrassing childhood memories, we’re able to see an entire world of influence that helped create the personality we see on screens and stages.  Pegg recounts, in great detail, the feelings and reactions he was searching for the very first time he intentionally tried to solicit a laugh with a joke. While we hear a lot of celebrities in recent years jump on the ‘geek bandwagon,’ Pegg openly relates his first feelings of love and romance to the feelings he experienced when discovering Princess Leia. He describes his transition from being weary of horror movies, to growing a self-proclaimed obsession with the genre. What’s particularly impressive about the way these stories are recounted is the way they’re presented.  The way Nerd Do Well is written feels so candid and natural, that it seems more like having a conversation with the author than just reading his history.

Nerd Do Well is a fantastic look into what inspires a person to pursue a position in the public eye, and what it takes to get there. From this memoir, we can very clearly learn that a strong love of Star Wars and zombies will get you farther in life than you ever imagined.  And while I, personally, would have loved to hear more on Pegg’s reaction to his likeness randomly showing up in The Boys, hopefully this inspiring memoir will now allow him to write more about the dashing superhero and his robotic butler.


I absolutely want my own Canterbury.
