Ninzen Martial Arts

12 Ninja Mind Codes, Kage no Michi, and a journal for the unseen.

Walk the Unseen Path.

What is Ninzen?

Ninzen is Eric Covey's dojo, a martial expression gathered into a single path. Within it, Kage no Michi, the study of unseen forces that influence behavior, perception, and action, joins the three ninja manuals with the twelve Ninja Mind Codes. Ninzendo holds the teachings. The Unseen Path is how you carry them into everyday life.

It combines:

martial training ·breath practice ·perception ·emotional discipline ·contemplative practice ·historical inspiration from shinobi writings

It is not an attempt to recreate medieval ninjutsu.

The Unseen Path is how these teachings are lived: the way of the modern shinobi.

A Glimpse Inside

Ninzen is a disciplined path of breath, perception, and restraint, drawn from the shinobi manuals and lived in modern life. The full teachings, the three manuals, and the Journal are open to members. What follows is a taste.

Sample Reading

“The shinobi did not master the spectacular. He mastered the ordinary until it became invisible: breath held one second longer, attention held one beat longer, restraint held one impulse longer. Mastery is what remains when performance is removed.”
