During this episode of KUDEN! Radio, we’ll e diving into the Ninja’s Mikkyo “secret knowledge” and ‘mind-science’ to uncover the three aspects of success, and what we in the martial arts tend to call Mastery… …and how each one, from the perspective of Ego, can create the illusion of success.

E187 – KUDEN! – The Difference Between Doing & Knowing Why 28.11.2023

During this episode, we’re going to be taking a look at the difference between two mindsets. Each one should be a part of the overall journey of our progress towards Mastery, but one of them can become a trap that not only keeps us chained to lower levels of development, but which also sets us […]

E186 – KUDEN! – An Important Secret About Mentors 21.11.2023

During this episode, we’re going to explore the differences between instructors, teachers, and mentors, with a specific focus on the latter.

In this episode, we’ll be exploring the timeless lessons that have been passed down by warriors and enlightened masters proven to produce (at a minimum) above-average results.

e184 – KUDEN! – Responsibility & the Cost of Inaction 31.10.2023

In the business world, there’s a concept called ROI or “return on investment”. This includes the benefits of what we get for putting in the time, effort, and resources along with the accomplishment of the goal. In the martial arts and self-defense realm, this is the black belt or skills necessary to make ourselves and […]

e183 – KUDEN! – Healthy Doubt vs Douchey Disrespect? 24.10.2023

If you’ve been around in the martial arts and self-defense realms for any significant length of time, then you’re sure to have run into several different personality-types, both in the form of well meaning students, “outsider” naysayers (you know, the “that doesn’t work” crowd) – those who are willing to even get verbally or physically […]

e182 – Elephant-Herding and…Success? 17.10.2023

In the Ninja’s Mikkyo esoteric ‘mind science’ study, there are are more than a few symbols used to convey everything from energies, to actualized human potentials, to processes and interactions between these things. Some of these can seem fairly obvious, or at least easily grasped when you learn about them, others have meanings far beyond […]

E181 – KUDEN! – Why the Ninja’s Sanmitsu Doesn’t Work! 10.10.2023

If you’ve been studying, or at least interested in the full system of self-protection and life-mastery known an Ninjutsu (and not like those merely focused on the unarmed combat with some weapons thrown in and calling it ‘Ninjutsu’, then you’ve most likely heard of the Ninja’s power and success principle known as SANMITSU – ‘the […]

e180 – KUDEN! – Kata, Self-Defense & the Battlefield! 03.10.2023

If we’re serious about training to be as prepared as possible for the worst and most unthinkable situations, we need to be very clear about both what that situation could be like – what will be going on inside what I call “the bubble” – and – what we’ll need to do within the context […]

e179 – KUDEN! – Fudo-Myo: Knowing When to Roar! 25.09.2023

One of the concepts that anyone who’s been around the art of Ninjutsu for any significant length of time has heard of is that of fudo-shin (‘Immoveable heart’), which itself is also embodied by the character, Fudo-Myo ‘Immoveable Light King/Queen’, in the Ninja’s Mikkyo esoteric mind-science study of enlightened potential. Any one of the hardest […]

e178 – KUDEN! – Controlling the Power of Self-Talk! 19.09.2023

One of the most common success and personal development tools taught by self-help “gurus” and used by many of those trying to create positive change, is that of positive affirmations – Using the power of speech to manifest change. But many find that these statements, supposedly having the power to change your ability to produce […]

e177 – KUDEN! – Why Ninja Wear Black (Not Stealth!) 11.09.2023

One of the most recognizable images when it comes to the Ninja warriors of ancient Japan is their shinobi shozoku – the so-called ‘ninja uniform’. And one of the biggest misconceptions and misunderstandings surrounds, not just the parts of it, but it’s color…the color black! Most believe that this is because of stealth. And like many […]

e176 – KUDEN! – The Secret to Winning Every Fight! 07.09.2023

In the ancient scrolls and texts that have been passed down to us by our warrior and spiritual ancestors, there are secrets to accomplishing things that seem impossible to most. Unfortunately, many also seem to be so “simple” that one can easily roll his or her eyes at them and keep on doing what they’re […]

e175 – KUDEN! – Avoiding “Yappy-Dog” Syndrome 29.08.2023

In this episode, we’ll be taking a look at something that not only turns off those who could be potential and beneficial connections for us, as-well-as lowering us on the “food-chain” in the world of real-warriors; but serves to further diminish our influence over our lives and our ability to actually attain the goals, power, […]

E174 – KUDEN! – Defending Against Dream-Killing Fears 22.08.2023

In this episode of KUDEN! Radio, I’ll be uncovering something at the root of failure, or just plain inactivity, for many. This is highlighted in the core teachings of the Ninja’s Mikkyo ‘mind-science’ training and study in several different ways – each being a key to unlocking our potential to break-free from the limitations and […]

e173 – KUDEN! – Martial Arts, Self-Defense & Respect 15.08.2023

During this episode, we’re going to be diving into a topic that everyone thinks they know and, by their actions at least…think they have an opinion on which dictates or allows them to justify their actions in different ways situations. I’m talking about Sonkei & Reikishi – Respect and Etiquette. We’ll be exploring this character trait and success […]

e172 – KUDEN! – Karma’s a Bitch! 08.08.2023

One of the problems we encounter when we’re trying to grow and progress in in thinking that we can do it with the same mindset, habits, and choices which created our current reality. We can try to say new things, use slick titles, or set ourselves up in a way we think will produce the […]

e171 – KUDEN! – 8 ‘Conditioners’ of Our Ninjutsu Training 01.08.2023

We often discuss the trap of compartmentalizing our lives – of putting things into separate “boxes” – and missing the interconnectedness that is happening all the time. This is just as true of our Ninjutsu self-protection & personal life mastery training as well. During this episode, we’ll be looking at using the 8-Fold Path from […]

e170 – KUDEN! – Fighting vs Self-Defense Mentality 25.07.2023

If you read the comments left on self-defense videos, whether they’re on mind or anyone else’s material, where self-protection is the focus…you notice a HUGE, gaping, glaring discrepancy… …it’s that the vast majority of people leaving those comments…don’t know the difference between a “fight” – especially of the competitive variety – and a “self-defense” scenario […]

In this episode, we’ll be breaking down the differences in the quality of our choices, with both our day-to-day goals and responsibilities as-well-as with those pertaining to our Ninjutsu self-protection and personal development training.

E168 – KUDEN! – 4 Factors of Enlightened Training 11.07.2023

One of the first things that I was taught by my teacher is that for a Ninja, anything which could be used to create the results that he or she is looking for – anything that can speed up the process – should be considered and, if applicable, applied to serve the Shinobi warrior in […]

E167 – KUDEN! – What Are the Basics? 06.07.2023

A consistent and, yes, proper lesson heard by students again and again is about the importance of basics. This goes beyond the initial lesson heard by beginning students, but also as a reminder to intermediate and advanced practitioners. But, as odd as this may seem considering the lists of so-called “official techniques”, what are the […]

E166 – KUDEN! – Another Blade Avoidance Test? 26.06.2023

One of the most talked about aspects of Bujinkan Ninjutsu training is the taking and passing of the sakki – blade avoidance test – for Godan, 5th degree black belt, and where one becomes a Shidoshi (‘Teacher of the Warrior Ways of Enlightenment’). But, within the Warrior Concepts’ Black Belt & Life Mastery curriculum, the […]

E165 – KUDEN! – GANBATTE & “Keep Going!” 20.06.2023

One of the most common phrases, next to the word: “play!”, that any student of the Bujinkan Ninjutsu and Budo-Taijutsu (yes, there is a difference!) has heard from Soke Hatsumi over the years is the admonition to: “Keep Going!” During this episode, we’ll be looking at the meaning behind this phrase as it relates to […]

E164 – KUDEN! – Confidence vs Arrogance (…?) 16.06.2023

Have you ever had self-confidence called into question? Have you ever made a comfortable decision about something, demonstrate something that someone needed to learn, or expressed yourself from a place of knowing and had someone call you…arrogant? During today’s episode, based on a topic submission from one of our listeners, we’ll be looking at the […]
