At Medicine Festival 2026 in Reading, UK, Radhika Das stepped into the role of sound healer, leading a room full of strangers in one of the oldest spiritual practices known to human culture. The power was immediate: within moments of her voice finding the opening notes of the maha-mantra—"Hare Krishna, Hare Krishna, Krishna Krishna, Hare Hare; Hare Rama, Hare Rama, Rama Rama, Hare Hare"—the collective breath of the festival shifted. What Das was channeling that afternoon is far older than any single tradition or moment: the liberating force of transcendental sound.
What Is Mantra, and Why Does It Matter?
The word mantra comes from Sanskrit and carries within it an entire philosophy of human transformation. It means "that which liberates and cleanses the mind." A mantra is not simply a collection of syllables to be repeated mechanically. It is a sacred sound formula that, when vibrated repeatedly, becomes a process of purifying the heart and mind. The theory behind this is not mystical hand-waving but a deliberate technology: through the rhythmic repetition of specific phonetic combinations, the inner light that already exists within each person is invited to shine outward into every aspect of daily life.
The simplicity of this approach belies its power. You do not need to be spiritually advanced to begin. You do not need years of preparation. A mantra works by its own resonance, gradually loosening the knots of mental turbulence—the stories we tell ourselves, the fears we rehearse, the grief we hold—and allowing what lies beneath to emerge. This is why chants, prayers, hymns, and the recitation of sacred texts appear across every spiritual tradition throughout history and throughout the world. The mechanism is universal even if the words change.
The Maha-Mantra and Its Awakening Power
Of all the mantras preserved within the Indian spiritual tradition, the maha-mantra holds a particular place. Its construction is precise: it names the divine in two of its primary forms—Krishna and Rama—and invokes the divine feminine principle, Hare. The mantra does not ask for anything. It makes no petition. Instead, it functions as an address, a direct calling-in of the presence that the tradition teaches is already within and around us. According to the philosophy that frames this practice, the maha-mantra awakens the heart to its divine nature and brings about joy and true inner satisfaction—not the fleeting pleasure of circumstance, but the stable contentment that comes from knowing one's own essential nature.
When Das led the room through the maha-mantra at Medicine Festival, she was not performing; she was conducting an ancient technology. The arrangement she used was inspired by HH Sacinandana Swami and HG Sri Prahlad Das, and it demonstrated the care that contemporary kirtan artists bring to this ancient form. The entry to the kirtan consisted of meditative vocals and piano, creating a mood designed to inspire loving devotion—or bhakti, the Sanskrit term for the yoga of the heart. This was not incidental: the entire sonic architecture was built to open participants to emotional vulnerability and collective prayer.
Building Community Through Collective Sound
A crucial moment in Das's kirtan came when she asked the room to step into greater intimacy. At around five minutes into the performance, she invited participants to reach out and grasp the hand of the person next to them. For many in the room, this was indeed "a little out of the comfort zone," as she acknowledged. But she invited them to try anyway. As the chanting continued, she reframed the act: "I want you to pray for the person," she said. "Don't pray for your own peace. Don't pray for your own. Pray for peace on this land, on this place we all have." Close the eyes, open the heart, she instructed. Every heart.
This was the reversal at the heart of kirtan practice: the solitary, introspective meditation becomes an instrument of collective care. By holding another person's hand while chanting the divine names, participants moved from using the mantra for personal purification into using it as an act of service. The self-orientation of spiritual practice—which can easily become narcissistic—was dissolved into the larger body. This is why kirtan is considered a form of bhakti yoga, the yoga of devotion, rather than a passive listening experience. Everyone present becomes an instrument through which the healing frequency moves.
The Musical Architecture of Modern Kirtan
Das did not perform this kirtan alone. The ensemble she led included backing vocals and kartals (finger cymbals) from Ananda Monet, Daivī-kumārī, Shyamali Buddhdev, and Radha Sundari. Keli Woods brought guitar and piano, Michael Goodey anchored the low end on bass, Abhay Buddhdev played the mridanga (a classical Indian drum), Tadas Mickevicius added saxophone, and Nayan Pankhania provided whompers—hand-drum patterns that kept the rhythm alive. This was not a folk practice; it was a carefully arranged contemporary expression of an ancient form.
The production quality reflected the seriousness with which modern kirtan artists approach their craft. The sound was engineered and mixed by Tabla Tom, filmed by Filmwork Studios, and edited by Hannah Brown. What emerged was a professional documentation of a sacred practice—preserving both the authenticity of the tradition and the immediacy of the live moment. The music breathed with the same sophistication you would expect from any serious musical performance, yet it remained rooted in the singular purpose of kirtan: to open the heart and awaken the innate brilliance within.
Why Sacred Sound Still Heals
In an era when many people feel isolated despite being perpetually connected, and when the noise of daily life drowns out inner quiet, the power of mantra becomes increasingly relevant. The maha-mantra does not require belief in any particular theology. It functions through resonance—through the direct vibrational impact of sound on the nervous system and the mind. When a room full of people chant together, something neurological and something transcendent occur simultaneously. Brain imaging studies have shown that chanting activates regions associated with self-referential thinking, memory, and emotional processing. But the subjective experience—the opening of the heart, the dissolving of separation, the sense of joy—points to something that neuroscience has not yet fully mapped.
Das understood this when she closed the eyes of the festival and opened its heart. She knew that in that moment, the room was not thinking about kirtan; it was being kirtan. The mantra was not something performed by her for the audience. It was something that moved through all of them, binding them into a single organism of devotion. That is the ancient promise of transcendental sound, and it remains as vital today as it was centuries ago.
Where to go from here
If this experience resonates with you, consider exploring a live kirtan session in your area. Unlike some spiritual practices, kirtan requires no prior knowledge or belief system—only a willingness to open and chant. You might begin with the maha-mantra itself, learning its syllables and letting them settle into your own practice. Read more about the philosophy of bhakti yoga and how devotional practice differs from other forms of yoga. Explore recordings from contemporary kirtan artists who are preserving and evolving this tradition. And most importantly, experience the collective power: find a gathering where you can chant with others, hold hands, and feel the resonance that happens when many hearts vibrate as one.
