Apprentice To Power: The Rubber Band Principle
(Notes from our Nature Based Training)
The morning fog hadn't yet burned off the Santa Cruz Mountains when Lunia Sensei stopped us mid-training. We'd just finished our fifth lap around the park—about 1,600 meters of running interspersed with kicks and strikes—and our bodies were screaming for rest. Instead, he instructed us to stand absolutely still. Not a casual rest position, but complete motionless meditation. For eleven minutes.
The contradiction was maddening. While running, every fiber of my being had begged to stop. Now, given permission to be still, my legs twitched with an almost desperate need to move. My mind, which had pleaded for rest moments ago, was suddenly cataloging a thousand reasons why standing still was impossible: my calf was cramping, my back itched, surely eleven minutes had passed already.
Lunia Sensei watched us with that particular quality of attention that makes you feel both completely seen and not judged at all. "What does this tell you about your mind?" he asked quietly.
One of the other students—a software engineer who'd been training for six months—laughed with sudden recognition. "Don't trust it."
"Exactly," Lunia Sensei said. He pulled a rubber band from his pocket, one of those thick industrial ones he sometimes used for resistance training. "Your mind is like this. It wants what it doesn't have. While you ran, it wanted stillness. Now that you have stillness, it wants movement. The mind is not your ally—it's a parasite that feeds on your life energy."
He stretched the rubber band between his hands, slowly, deliberately. "But here's what most people miss. The mind isn't the enemy either. It's a tool. Like this rubber band. If I stretch it and hold it here"—he extended it to near its limit—"and never release it, what happens?"
"It loses its ability to contract," I said.
"Yes. And if I leave it in a box, never used, through heat and cold, and then one day try to stretch it?" He mimed a snapping motion. "It breaks. The way you keep a rubber band healthy is the same way you keep your tendons, ligaments, and fascia healthy—by moving it gently between its extremes."
This wasn't just an anatomy lesson. What Lunia Sensei was describing was a fundamental principle of human development that extends far beyond the physical body. In neuroscience, we call it neuroplasticity—the brain's ability to reorganize itself through varied experiences. In ancient wisdom traditions, it appears as the dance between yin and yang, the necessity of opposites for wholeness. But standing there in that park, with my muscles trembling and my mind chattering, I understood it in a new way: we need both the push and the pull, the effort and the rest, the noise and the silence.
"This is why we train between extremes," Lunia Sensei continued. "Not to torture you, though I know it feels that way. But to give you range. The more ability you have to be in extreme action, the more ability you'll have to rest in extreme stillness. The greater your capacity for stillness, the greater your capacity for explosive movement. It's elastic. You have to keep moving it."
He looked at each of us in turn. "Where did your body give up first today? Or was it your mind?" The question hung in the morning air, mixing with the scent of bay laurel from the nearby trees. "This is your weak spot. This is what needs strengthening. And you can't strengthen it by avoiding extremes—you strengthen it by learning to dance between them."
The parallel to modern life struck me immediately. We live in a culture of moderation, of staying in the comfortable middle. We're told to "find balance," which usually means avoiding anything too challenging or too restful. We fill every moment with activity, then wonder why we can't truly relax. Or we binge rest—collapsing in front of screens—then wonder why we have no energy for meaningful action.
What Lunia Sensei was offering was something more sophisticated: not balance as stasis, but balance as dynamic range. The ability to access both ends of the spectrum and everywhere in between.
"Viktor Frankl wrote about this in a different context," Lunia Sensei said, referencing the Holocaust survivor and psychiatrist. "In the concentration camps, what separated those who survived from those who didn't wasn't physical strength. It was whether they found meaning in their suffering. If they found meaning, they could endure. If they didn't, the suffering consumed them."
He let the rubber band contract back to its natural state. "So here's the question you must answer: What are you training for? It should be something deeper than 'I want to look good' or 'I want a six-pack.' Those might motivate you at twenty, but not at your age. You need to know: Am I training for culture, combat, competition, or self-cultivation? What am I actually cultivating?"
The moment you find that meaning, he explained, the suffering becomes worth it. The extremes become necessary rather than punishing. You're not just enduring—you're expanding your range, increasing your elasticity, becoming more fully capable of meeting whatever life demands.
Try This:
This week, practice conscious movement between extremes in small ways. Set a timer for five minutes of intense focus on a single task—no multitasking, no interruptions. Then immediately shift to five minutes of complete rest—no phone, no input, just being. Notice what your mind does at each extreme. Does it beg for relief during focus? Does it itch for stimulation during rest?
Apply this to physical practice too. Take a brisk walk that pushes your cardiovascular system, then sit in complete stillness for an equal amount of time. The key isn't the specific activity—it's the deliberate oscillation between opposites and the awareness you bring to how your mind responds.
Finally, ask yourself Lunia Sensei's question: What am I cultivating? Write it down. Because without meaning, these extremes are just torture. With meaning, they become the very practice that expands your capacity for life itself.
The principles that emerge in our outdoor dojo—whether in Mountain View's morning-misty parks or the San Lorenzo Valley's ancient redwood groves—aren't meant to stay on the training ground. They're seeds of transformation, waiting for the soil of consistent practice and authentic community.
What makes training with Lunia Sensei unique is how seamlessly ancient wisdom adapts to modern challenges. In any given session, you might find a software engineer learning patience alongside a teacher rediscovering strength, or a teenager understanding discipline while a grandmother demonstrates fierce grace. The mountain doesn't care about your resume—only your sincerity.
This is world-class martial arts training that changes lives, not just techniques. If these stories spark recognition in you—a sense that you're meant for something deeper than the surface life allows—we invite you to explore what training with us might offer.

About Viktor Frankl: Viktor Frankl (1905-1997) was an Austrian psychiatrist and Holocaust survivor who founded logotherapy, a form of existential analysis. His book Man's Search for Meaning (1946) chronicles his experiences in N**i concentration camps and presents his theory that finding meaning in suffering is essential to survival and human flourishing. The work has sold over 10 million copies and remains one of the most influential books in psychology and philosophy.
