In the Space Between Lessons: A Tribute to a Sensei and Fellow Seeker

In the stillness of the dojo, where the scent of tatami mingles with quiet breath, I came to know a man whose life was not merely shaped by Karate—but who shaped Karate into a life. Ranjit Sensei did not teach with volume; he taught with presence. His「基本」or, Kihon (basics) was accurate, his「型」or, Kata (form) was completely fluid, and his「組手」or, Kude (sparring attack) was measured not by aggression, but by awareness. Each movement reflected 「生き甲斐」or, Ikigai – a life lived with purpose, discipline, and quiet joy.

He understood that the path of「道」or, the Michi (road) is not a destination but a rhythm. In the cadence of training, he revealed the essence of 「間」or, Ma (the space in between) strikes, the pause before response, the silence that holds meaning. In that interval, we learned to listen—not just to our opponents, but to ourselves.「間」was not emptiness; it was an invitation. His teaching embraced 「わびさび」or, wabi-sabi (subdued refinement) which is the beauty of imperfection, the grace of aging, the dignity of the incomplete. A worn-out「空手着」or, Karate-Gi, (karate-uniform), a crooked stance corrected with patience, a student’s faltering spirit lifted with a nod. He never demanded flawlessness; he asked only for sincerity. In his eyes, effort was always more sacred than outcome.

And he practiced「現地現物」or, Gemba Genbutsu (go and see.) He never taught from abstraction. Every correction came from observation, every insight from experience. He walked the floor, watched the form, felt the energy. His wisdom was not theoretical; it was earned, step by step, breath by breath.

But what set him apart was not just his mastery of technique but his embodiment of「改善」or Kaizen (improvement.) He believed in continuous improvement, not as a slogan, but as a way of life. Each day was an opportunity to refine, to deepen, to grow—not just in skill, but in character. He taught us that progress is not a leap, but a quiet accumulation of honest effort.

In moments of reflection, he would speak of「神」or, kami (spiritual deities) but not as distant deities, instead as the spirit that dwells in all living things. The spirit in the bow, in the breath, in the wooden floor that bore our weight. He reminded us that Karate is not just physical—it is spiritual. That every action, when done with reverence, becomes truly sacred.

And in his leadership, he practiced「ホウ・レン・ソウ」(Hou-Ren-Sou), the Japanese principle of communication:「報告」(report),「連絡」(inform),「相談」(consult). He fostered a culture of trust, where students felt safe to speak, to ask, to share. He did not command; he actually conversed. His dojo was not a hierarchy, but a living community.

To train under him was to enter a space where dharma met 「道」the road, the path, and, the way! Where duty was not imposed, but slowly discovered. Where the greatest opponent was not another fighter in the dojo, but the ego within the self. Ranjit taught all his students that Karate begins and ends with respect—not just for others, but for the path itself – the path leading towards discipline, respect, resilience, presence, balance, and, dharma.

I remember the way he bowed, not out of ritual, but out of recognition. Each bow was a gesture of gratitude: to the art, to the ancestors, to the moment. In his presence, I learned that strength is not domination, but controlled restraint. That mastery is not control, but absolute compassion for fellow beings.

He was not just a Sensei. He was a mirror. A compass. A quiet force that shaped lives without fanfare. His legacy is not in trophies or titles, but in the way his students walk, speak, and live. In the way we pause before action. In the way we strive without pride. In the way we bow with sincerity.

I remain grateful. For the lessons I learnt, for the silences unheard, for the spirited values he shared. His teaching lives on, not just in technique, but in the choices we all made, the values we upheld, and the breath we took before we even began. In every moment of「残心」or, Zanshin (the lingering awareness after the strike), I carry his presence. And in that awareness, I remember: the way is long, but the path is clear.

Dojo, Dharma, and Destiny

In 1981, beneath Kurukshetra’s merciless sun, Ranjit ordered me to sprint—once, then yet again. My legs gave way, breath tangled in my chest, cramps clawing at my resolve. Yet in that collapse, something awakened—not muscle, not pride, but a quiet ember of discipline, the first whisper of stillness within motion. That moment was not about karate technique. It was about life: discipline, focus, and the stillness beneath motion. I stopped learning karate soon after, but I gained something far more enduring—a friendship. Ranjit was no longer just my sensei; he became my helping companion on the path.

Fast forward to 2010. India was producing engineers by the millions, and I was one of them—restless, searching, gasping again, but this time for purpose. That search led me back to Dr. Ranjit: a physics expert, a black-belt Zen warrior, and now my guide not in the dojo, but in the world of academia and industry.

Over countless cups of chai in glass tumblers, our bond deepened. His scientific rigor and quiet compassion for struggling students sparked a shared mission: to reimagine Bharat’s engineering education. As a Computer Science professor, Ranjit brought Zen-like clarity to our joint research. We uncovered systemic flaws and proposed simple, human solutions—mentorship, English fluency, and student-focused learning. These ideas lit up classrooms like rows of Deepavali diyas.

Inspired by his teachings, I launched a Business School in Tokyo, embedding his principles into courses on optimization and sustainability. Our collaborative papers on cloud computing became roadmaps—not just for technology, but for thoughtful entrepreneurship.

Sensei Ranjit’s dojo was never just a room or a congregation. It was a deep philosophy. He taught me to unite discipline with compassion, science with the soul. That sweaty sprint and those shared cups of chai shaped my destiny.

Today, his new platform—Karate Insight: Awakening the Warrior Within—offers timeless guidance for those seeking balance, strength, and purpose. (Scan the QR code with your mobile camera.)

Honoring his journey shows us that small moments can inspire major change.

Are you ready to awaken the warrior within?
