Mushashin: Understanding The Warrior Heart

Mushashin: understanding the warrior heart

What does mushashin mean?

The heart of a warrior?

I was asked this question last night after class and it took me a few moments to capture the feeling.

I could have given an academic explanation, a static definition: Mushashin is the heart of a warrior that allows them to make the needed decision in that moment regardless of the outcome, that it is the heart of a warrior that will guide a person every day in the martial arts.

Not just practicing the martial arts, or living the arts, but *being* the arts.

Yet, with martial arts being movement, these concepts of philosophy-spirituality in training are better expressed through action.

Developing mushashin is easy- just show up to the dojo to train every week.

We have reasons for practicing the martial arts, desires- perhaps to become something or learn something.

When you train at the dojo week after week, month after month, season after season, those desires get tempered.

Want that next rank?

It might take you a year of training.

Show up and work on it.

This tempering of desire, burns it away, so only the heart of a warrior remains, through committing to the training and showing up every week no matter what.

Mushashin is also found outside the dojo, the dojo being a sacred space, a safe space, it is easy to show mushashin in the dojo.

Taking the lessons of the dojo, how do you hold your heart outside the dojo?

When you are tested in life, interacting with others, and navigating society.

Do you behave as a warrior would behave?

The aim of the Shinmyoken dojo (school of the life giving sword) is to understand nature and the movement of being zero through taijutsu. The school exists to create and transmit this through the experience of isshi soden.

Located in Westchester New York, the Shinmyoken dojo is a martial arts training group founded in 2005 with the aim of coming together as martial arts friends to study the Japanese martial arts of Masaaki Hatsumi through the lessons of the Bujinkan dojo. 

As friends (buyu) we come together to grow, learn, and share our individual potential in this wonderful martial art. In our group there is no beginner or advanced classes, as we all have the capacity to learn the martial arts in great stride. 

No previous martial arts experience is needed, new members, and out of town or traveling Bujinkan buyu are always welcome. 

The focus of the group is to make progress each week in learning the martial arts, developing skill, self-defense ability, and an understanding of how and why people move. 

Training is supervised by Fred Feddeck who has been studying the Bujinkan dojo martial arts since 1993. 

In 2003 he was honored to take the godan shinsha with the training group later forming as a vehicle to study what he has been taught and experienced in the Bujinkan dojo martial arts. 

Joe Maurantonio, dai-shihan, is and continues to be his teacher and mentor. 


Training in budo taijutsu through our dojo is offered in three class formats. 

The first is our weekly Saturday morning classes from 9-11 AM at a local park in Yonkers which is accessible by car, bus, and Metro North train. 

Second is our regular weekly zoom class as a way to build on the physical practice-paired movements explored in our Saturday classes. 

Third is our monthly discussion class exploring martial arts philosophy, history, tactics, and kuden. 


Membership in the dojo is open to those eighteen years of age or older and who can abide by the rules of the Bujinkan. 

Those interested in joining the dojo will be asked to fill out a brief questionnaire as an introduction and meet with the head instructor before an invitation to watch a class will be extended, general martial arts questions and other training inquiries are also welcome.
