In the summer of 2026, at the World Yoga Festival in Henley-on-Thames, Radhika Das stood before a gathered crowd and opened a portal of consciousness through sound. What unfolded was not merely a concert; it was an act of spiritual alchemy—the channeling of transcendental vibration as a means to awaken the dormant brilliance within the human heart. The chant that carried this transmission was ancient, rooted in thousands of years of yogic and Hindu tradition: Om Namah Shivaya, Shiva Shambho, Mahadeva Shambho. Yet its arrangement was thoroughly contemporary, grounded in raw percussion and collective participation—a bridge between the eternal and the urgent now.
What Is Mantra, and Why Does It Matter?
The Sanskrit word mantra translates literally as "that which liberates and cleanses the mind." It is not incantation for its own sake, nor is it mere repetition dressed in spiritual language. According to the framework presented in this live performance, mantra functions as a sacred sound formula vibrated repeatedly as a process of purifying the heart and mind, allowing the innate brilliance within to shine into every aspect of our lives. The power lies not in the meaning alone—though meaning matters—but in the *vibratory frequency* of the sound itself, its capacity to resonate through the nervous system and shift consciousness at a cellular level.
This understanding reflects practices spanning centuries and continents: Vedic chanting, Sufi zikr, Gregorian plainchant, and countless prayer traditions have all recognized that sound, when wielded with intention and sincerity, carries the capacity to transform. The live kirtan at Henley-on-Thames was a direct expression of this principle—not as theory, but as lived, embodied practice.
Who Is Shiva, and Why Invoke Him Through Song?
The figure of Shiva occupies a unique position within the Hindu pantheon and within popular contemporary spirituality. Often depicted in meditation, adorned with a crescent moon and serpent, Shiva is understood in classical texts as the destroyer—yet destruction here means the dissolution of illusion, the clearing away of what obscures truth. In the Srimad Bhagavatam, one of Hinduism's most revered scriptural texts, Shiva is described as the opener of the portal toward devotion itself. As Radhika Das explained during the performance, "In the ancient scripture the Srimad Bhagavatam it is mentioned that Mahadeva Shiva is the opener of the portal towards devotion. He will feel loving sentiments towards divinity. Towards God, then Lord Shiva can open the portal. Sincere souls—I want to invite you to close the eyes and chant once more all together."
The mantra invokes two primary names and titles for this deity: Shambho, which means "auspicious," and Mahadeva, which translates as "Greatest deva"—or demi-god. In calling upon these names, the chanter is not so much praying to an external deity as awakening the principle of auspiciousness and greatness that Shiva represents within one's own consciousness. The gateway opens inward.
The Architecture of Sound: From Raw Percussion to Collective Voice
What distinguished this particular arrangement of Shiva Shambho was its structural DNA. The piece began with what Radhika Das described as "grooving, raw percussion"—a direct inheritance from her earlier studio recording titled Revealed (Shiva Shambho). This opening is crucial. Rather than beginning with ethereal vocals or a contemplative drone, the kirtan launched from the body, from rhythm, from the earth. Percussion instruments—the mridanga (a traditional South Indian drum), whompers, and kartals (hand cymbals)—created a sonic foundation that was primal and undeniable.
Over this foundation, Radhika Das's lead vocals entered, supported by backing vocalists and a guitar-and-bass ensemble that gave the sound both texture and harmonic depth. The arrangement reflected a modern sensibility: this was not a museum piece or a museum practice, but a living, evolving tradition that absorbed and integrated contemporary instrumentation while maintaining the essence of the form.
The ensemble itself—Radhika Das alongside Daivī-kumārī, Shyamali Buddhdev, Emilie Cobie, Radha Sundari, Keli Woods, and others—functioned as a collective voice. The call-and-response structure inherent to kirtan means that the leader initiates, and the community echoes and deepens the phrase. This is not a performance in the Western concert sense, where the audience sits passively; it is a collaborative invocation where every voice matters, where the boundary between performer and participant dissolves.
Presence as the Deepest Practice
Midway through the performance, Radhika Das paused and offered a directive that cuts to the heart of what mantra practice is really about. "There is other things going on," she said, acknowledging the festival environment, the distractions of the external world. "Try to be present. Try to be present all together." This simple instruction—be present—is the true technology. The mantra is the vehicle, but presence is the destination.
Presence, in the yogic and devotional tradition, means a kind of total availability to the present moment, free from the mind's habitual commentary and resistance. When the nervous system is flooded with the repetition of sacred sound, when the body sways, when the voice joins with other voices in unified vibration, the thinking mind—which constantly judges, plans, regrets, desires—can finally rest. In that rest, something subtler awakens: a sense of connection, of belonging, of recognition. This is what the ancient texts mean when they speak of the "innate brilliance within" beginning to "shine out into every aspect of our lives."
The Lineage of Transcendental Sound
Radhika Das situated her work within a vast historical continuum. The description of the performance notes that "the power of transcendental sound has been channeled by various traditions, throughout history and throughout the world. Chants, prayers, hymns, recitation of sacred texts, can awaken our inherent spiritual nature." This is not cultural appropriation or spiritual tourism; it is recognition of a universal human technology that has been discovered and refined independently across civilizations.
The live kirtan represents a contemporary expression of practices that predate Christianity, Buddhism, and Islam by centuries. The Vedic seers understood that *nama* (name) and *rupa* (form) are inseparable—that to chant the name of the divine is to invite its presence. This principle has echoed through every major spiritual tradition. What Radhika Das and her ensemble offered at Henley-on-Thames was both a continuation of this lineage and a radical reimagining: ancient wisdom clothed in contemporary sound design, global ensemble, and an open invitation to every person present to become a co-creator of the sacred moment.
Where to Go from Here
For those drawn to this work, the path is straightforward but not simple. Seek out kirtan gatherings in your community—they happen in yoga studios, temples, conscious venues, and online platforms worldwide. Begin with listening, with presence. If you find a mantra that resonates—whether Om Namah Shivaya or another sacred formula—commit to repetition. Not as obligation, but as devotion. Twenty minutes of steady chanting, daily, will begin to shift your nervous system, to quiet the restless mind, to open what the tradition calls the "gates of spirituality." The power is not in the perfection of your voice or your understanding, but in your sincerity. As Radhika Das invited: sincere souls close your eyes, offer your presence, and allow the sound to do its ancient work.
Om Namah Shivaya is a Sanskrit mantra that translates to "I bow to Shiva." In yogic tradition, Shiva represents the principle of consciousness itself, and the chant is an acknowledgment of that divine principle both within the universe and within oneself. Repetition of this mantra is believed to purify the mind and awaken spiritual awareness.
While the mechanisms are still being studied, neuroscience research suggests that repetitive chanting can calm the amygdala (the brain's fear center), increase parasympathetic nervous system activation (the rest-and-digest response), and create coherent brainwave patterns. The rhythmic vibration also appears to stimulate the vagus nerve, promoting relaxation and emotional regulation.
Yes. Kirtan is fundamentally about the transformative power of sound and collective presence rather than dogmatic belief. Many practitioners approach it as a sonic meditation or a means to access deeper states of consciousness, irrespective of their religious background or spiritual framework.
Kartals are small hand cymbals that keep time and add brightness to the sound. The mridanga is a two-headed drum from South India that provides the foundational rhythmic pulse. Together, these percussion instruments create a grounding, embodied quality that anchors the vocal invocation.
Begin by listening to recorded kirtans to familiarize yourself with the melodies and call-and-response patterns. Then, choose a mantra that resonates with you and chant it aloud for 10-20 minutes daily, ideally at the same time each day. You can use a mala (prayer beads) to count repetitions if desired. The key is consistency and sincerity rather than perfection.
Shiva is often called the destroyer—not in a negative sense, but as the force that dissolves illusion and ignorance. Unlike deities associated with creation or preservation, Shiva represents transformation and transcendence. In devotional practice, he is invoked as the opener of the gateway to spiritual realization and direct experience of the divine.
Yes, kirtan is considered bhakti yoga—the yoga of devotion. While many people associate yoga with physical postures, yoga encompasses multiple paths: karma yoga (action), jnana yoga (knowledge), and bhakti yoga (devotion). Kirtan activates the devotional pathway through the power of sacred sound and collective participation.
While both involve repetition of words or phrases, mantra is understood to carry an intrinsic spiritual frequency and power independent of rational meaning. Affirmations operate primarily through the thinking mind and its capacity for self-suggestion. Mantra, by contrast, is believed to work at deeper levels of consciousness through vibratory resonance, even when the conscious mind is quiet.
