The Path
NINZEN
Ninzen Martial Arts is Eric Covey's dojo, a martial expression gathered into a single path. Within it, Kage no Michi translates the durable principles of the three ninja manuals and the twelve Ninja Mind Codes into a modern inner discipline. Ninzendo is the larger body of teachings that holds the path. The Unseen Path is how you carry it into everyday life.
Trained awareness under pressure. Not just fighting. Seeing what is hidden. Resisting the reflex. Returning to weight.
The name itself holds the practice: Nin (忍): stealth, endurance, inner discipline. Zen (禅): stillness, mindfulness, silent knowing. Dō (道): the Way, always implied, never absent.
Awareness must be trained, not assumed.
The whole system in one breath: Purpose. Perceive. Breathe. Choose. Act. Review.
The complete path is written down: Ninzendo: From the Ninja Manuals to the Unseen Path, first edition, 2026.
