From Practice to Mastery
Author's Note This article represents my personal understanding and interpretation of traditional karate as taught by Hidetaka Nishiyama Sensei and followed by Avi Rokah Sensei. While I have endeavoured to accurately represent their teachings and methodology, any errors, misinterpretations, or misunderstandings are entirely my own. The insights and principles discussed here reflect my current level of comprehension as a student of this art, not the definitive word of my teachers. Andrzej
From the Floor to the Practice
Understanding the mechanics of the pushes and engaging the inside muscles correctly are essential, but technique is more than mechanical precision. In kata and kihon, we learn to forge these forces into a singular purpose. You can have perfect alignment and the right internal pressure, but if the intent is absent, the technique remains hollow. This is where the mind and eyes become the final link in the kinetic chain.
Nishiyama Sensei taught that “the eyes guide the body” and “kime is from the eyes.” The eyes lock onto the target, establishing the line of action for the force vector, while the mind provides the intent [20, 24]. This is not just a metaphor—it is the physical trigger that aligns the unit. The mind and eyes initiate the first push, triggering the centre to drive toward the target. They maintain zanshin—continuous awareness—ensuring there is no kyo, no “hollow” moments where the internal pressure drops or the connection to the floor is lost [25].
As training deepens, this evolves into the mastery of transition, or what we call the recycled vector. In advanced practice, the end of one move becomes the start of the next [23, 24]. The second push of a block, which roots you to the floor and stores energy in the fascial spring, must instantly become the first push of the counterattack. The energy is never discarded; it is redirected. If you “reset” between techniques, you have lost your connection to the floor and the momentum of the encounter [7].
The Ultimate Test: Kumite
We do not train to accumulate points; we train for Todome, the decisive finishing technique. Nishiyama Sensei taught that the goal of every movement is to stop the opponent – not to score, but to finish. In kumite, we find out if these principles actually live within us when the target is moving and fighting back. The principles of floor pressure and straight-line force do not change in a fight; they simply have to be applied faster and more precisely.
We use ukimi—the feeling of suspending the legs from the pressurized centre—to stay mobile [23]. This keeps the feet “light” for movement, but the centre “heavy” with potential energy. We are always adjusting our feet so that a first push can happen at any moment. We don’t walk; we glide, maintaining our connection to the floor even while shifting.
Distance (maai) is not just about the space between you and the opponent; it is about pressure too. Even when standing still, the “expansion” created by internal pressure and ground connection should be felt by the opponent. When you strike, you don’t reach with the arm; you use the centre to carry that floor pressure into the target [8, 19]. If you lose your connection with floor, your strike becomes “hollow” and has no weight behind it.
Watch the Interaction of Rhythm and Ground: Avi Rokah - Catching and Breaking Rhythm https://www.youtube.com/watch?v=wUH6Hyk7Rts Observe how the breath and internal pressure act as the "switch" for rhythm. Notice how the connection of the back foot to the floor is what allows the karateka to stay elastic and responsive.
Biomechanically, traditional karate is the study of how a human being connects to the ground. We press the floor, we align the body, and we deliver our mass through a straight-line vector. By moving away from raw “muscular” strength and toward a deeper understanding of pressure, we bring the art’s philosophy into physical reality.
In the end, the physics of karate is not a set of rules to be memorized, but a tool for removing obstacles from our path. The relentless study of mechanics—the floor, the muscles, the fascia, the breath—serves a deeper purpose. It removes the clutter of our own tension and ego because the floor cannot be argued with or fooled. When this mechanical precision becomes internalized through practice, technique begins to look effortless.
But mechanics alone are not enough. As Sensei Rokah teaches, we must learn to “think by mind (heart), act by ki”—to observe without judging, to react through breath rather than conscious thought. This territory of intuition and ki energy is beyond the scope of this article, yet it is equally essential to Todome. Mastery in traditional karate as taught by Nishiyama Sensei is when Beginner’s Mind—Shoshin (also pronounced Nyuanshin)—meets a body perfectly in tune with the ground. At that moment, the search for Todome ends where it began: with a clear mind and a solid floor. The strike is no longer something you do, but something the ground expresses through you [23, 24, 25].
