Shaiva Kali: Sixty-One

The relationship between Nadabrahman and Shabdabrahman is like that of cause and effect, seed and tree, silence and sound. Nadabrahman is the primordial vibration—consciousness's unstruck resonance; Shabdabrahman is that vibration's manifested form—consciousness's creative sound. In one, Brahman is silent self-revelation; in the other, He is active cosmic manifestation. Both are ultimately two aspects of the same truth—consciousness's soundless depths and its articulated echo.

In the interpretations of Tantra and Kashmir Shaivism, Nadabrahman doesn't merely mean audible sound; it is that subtle vibration from which both sound and silence arise. Abhinavagupta says, "Nadah kundalini shaktih pranavasvarupini"—meaning, Nada itself is Kundalini Shakti, who manifests in the form of Pranava or the sound Om. This Kundalini Shakti is consciousness's inner vibration, who reveals herself in the play of sound and silence. Thus when the Veda is called Nadabrahmasvarupa, it means—the Veda is that infinite vibration of infinite consciousness, from which both world and mind are born.

From the perspective of Advaita Vedanta, this concept of Nadabrahman goes one step deeper. Here it is said that first Brahman was in a waveless and nirguna state—that waveless consciousness itself vibrates in the form of "Om-kara." Creation begins from the sound Om, hence "Om" is called "Pranava"—meaning "primordial sound." Thus it is said, "Om iti etadaksharam brahma"—this Om is Brahman. All Vedic mantras arise from this Om-kara; this is why the Veda is called Nadabrahmarupa.

Here "Nadabrahman" and "Shabdabrahman" are actually two aspects of the same principle. "Nada" is Brahman's unstruck vibration—unmanifest and silent; and "Shabda" is its manifested form—where that unstruck vibration has been expressed in language, mantra, and words. Thus it is said—"the passage from Shabdabrahman to Parabrahman"—meaning the realization of silent consciousness through the medium of sound. The Veda is the bridge of that passage—which is of sound, but within that sound lies the presence of silent Brahman.

Therefore "Veda Nadabrahmarupa" is not some specific scriptural statement, but rather a profound philosophical conclusion. It declares that the Veda means not merely textbooks; they are the sound-form development of living consciousness. Reciting or hearing the Vedas thus means not merely uttering sentences, but returning through those sounds to the source of one's own consciousness. For sound is the path, sound is the manifestation, and the silence inherent in sound is ultimate liberation. As creation begins with sound, so too liberation merges into silence through sound. Sound is consciousness's first vibration, and the Veda is that consciousness's eternal echo—where Nada is Brahman, and Brahman is Nada.

Unstruck vibration and struck vibration—these two terms signify a fundamental duality in Indian Nadayoga, Tantra, and Shabdabrahman philosophy, expressing the distinction between consciousness's inner and outer sound-flows. These two levels complement each other—unstruck vibration is consciousness's soundless, primordial tremor, and struck vibration is that tremor's external echo, manifested in the world of sound, speech, and language.

In Tantra and Yogashastra it is said, "Nadam anahatam dhyayet"—may the seeker meditate on that nada which is heard without striking. The literal meaning of "ahata" is "born of impact," meaning sound arising from the collision of two objects. When sound occurs through contact of air, throat, tongue, and material substances—like when strings of instruments or the head of a tabla are struck creating sound—that is struck nada. But unstruck nada is not born from any collision; it is consciousness's inner resonance—which is heard in the depths of the heart, along the path of Kundalini's ascent, along the central channel (sushumna) of the spine.

Philosophically, unstruck vibration is the primordial vibration of Brahman-consciousness. It is that level where consciousness has not yet taken the form of sound, meaning, or emotion; it is merely oscillating in its own existence. This silent wave is called "Nadabrahman"—unmanifested sound. It is such a sound that lies beyond the limits of the auditory sense—experienceable in inward meditation, but inexpressible in language.

On the other hand, struck vibration is the functional form of Shabdabrahman. When unstruck consciousness becomes outward-facing and manifests, then its vibration becomes "impact-born" sound through contact with air and matter. This sound is our world of conversation, music, sound, and language. It is consciousness's manifesting power—the form of vimarsha shakti, which creates meaning, form, and emotion.

These two levels are called by Yogashastra "inner nada" and "outer nada." Inner nada or unstruck nada is consciousness's silent resonance, felt in the centers of heart, throat, and between the eyebrows. Outer nada or struck nada is physical sound, which is caught by the auditory sense. The relationship between these two is like cause and effect—unstruck vibration is the cause, struck vibration its manifestation.

In the language of psychology, unstruck nada is the vibrational field of the unconscious—where emotions and feelings exist in wave-form before becoming words. Struck nada is conscious expression—where that inner wave is transformed into thought and language. In Jung's view, unstruck nada is the soul's archetypal resonance, and struck nada is that resonance's symbolization.

Just as Carl Gustav Jung's psychology, at its deepest level, reveals through the concept of "Collective Unconscious" the primitive and universal stratum of human consciousness, so the Shabdabrahman theory of Indian philosophy is the philosophy of consciousness's primordial and fundamental vibration. In the dialogue between these two streams, a unique bridge is formed—where Western psychological archetypes and India's spiritual Shabdabrahman illuminate each other.

Jung had shown that deep within each person lies such a collective level where the archeological traces of all humanity's experiences accumulate—which he called the "Archetypal Field." On the other hand, Indian consciousness-philosophy has said that at the root of all creation lies Shabdabrahman—which is not any linguistic utterance, but the beginningless vibration of cosmic consciousness. Bringing these two streams together, we see that consciousness itself pulsates in a sound-filled archetypal vibration within itself.

In explaining this unity, the concept of two nadas is central—unstruck nada and struck nada. Unstruck nada meaning 'sound without impact'—this is such an inner vibration that continuously resonates in consciousness's depths without any collision or external friction. In Yogashastra and Tantra, unstruck nada is called para shabda, meaning sound's most primordial, supreme, and unmanifest form. It cannot be heard by the ears, it is felt inwardly, as a meditation-absorbed seeker feels in the heart's depths an indescribable flow of sound—which is creation's pre-flow, the beginningless endless vibration. This unstruck nada itself is cosmic consciousness's breath, within which lie as possibility all forms, all languages, all symbols. It is not any specific form, but the repository of form's potential—where everything is still unmanifest, but ready.

In Jung's psychology, unstruck nada can be understood as archetypal resonance—that primitive resonance of the soul which lies dormant in all humanity's depths. It is the fundamental vibration of the collective unconscious, where archetypes silently undulate. These archetypes are beyond language and culture; they are that silent sound situated at consciousness's roots, from which human thought, dreams, mythic imagination, and religious consciousness arise. Unstruck nada is thus a pre-psychological reality—consciousness's unmanifest and formless source, which echoes at every level of human existence.

When this unstruck vibration manifests itself through language, form, or symbol, then it becomes struck nada—'impact-born sound.' This is that sound born from collision, vibration, or contact—like the sounds of words, mantras, music, nature's sounds, or the utterance of mental emotions. In Indian philosophy this is manifest sound, vaikhari shabda, which is sense-perceptible. Struck nada is unstruck nada's symbolic form—a linguistic and form-filled expression of unmanifest consciousness. When a poet expresses deep inner anguish or love's feeling in words, those words are not merely external—this is the symbolization of their inner unstruck vibration. Similarly, when a seeker chants mantras, though the sound from their mouth is external, the source is that inner unstruck nada, which erases the boundary between sound and silence.

In Jung's psychology this very process is symbolization—where unconscious archetypes manifest on consciousness's stage in the form of dreams, symbols, or art. This is the movement from unstruck to struck—the journey from unmanifest to manifest. These two levels of consciousness are not mutually contradictory; rather they complement each other. Unstruck is the cause—infinite, unmanifest, formless consciousness; struck is the effect—its manifested form, finite and perceivable. There is a flowing relationship between them, as exists between wave and ocean, light and radiance, or emotion and language.

This philosophy teaches us that human consciousness is never isolated—in its depths continuously resonates that cosmic unstruck nada, which is the source of all experience and expression. Just as Jung had shown that each human soul is fundamentally a reflection of a great being, so the Shabdabrahman theory says—within every being operates the same nada, the same Brahman-vibration. Struck nada is the expression of that inner tune; thus human language, poetry, music, or prayer are all actually manifold echoes of that unstruck nada.

Finally it is understood that unstruck and struck nada are not opposites of each other, but two streams of the same consciousness. Unstruck is silence's nada, struck is its spoken melody. Unstruck says, "I am"—struck says, "I am manifested." Together they form an infinite dance of creation, consciousness, and language. This dance itself is the supreme mystery of Shabdabrahman—where silence transforms into sound, sound returns again to silence; where soul and world, emptiness and fullness, thought and expression unite in one undivided supreme resonance.

In Tantra it is said that the practice of unstruck nada means returning toward consciousness's source—where sound, thought, senses, and breath all merge into one. When the seeker begins to hear that inherent nada, then the sounds of the external world fade away, the mind becomes still, and consciousness awakens to its original form. In this state, struck sound gradually dissolves into unstruck sound—this is Nadayoga's ultimate unity.

Therefore, the difference between unstruck and struck vibration is actually the difference of consciousness's movement and direction. Unstruck vibration is inner-born, silent, primordial, and sky-pervading; struck vibration is outward-facing, dynamic, limited, and physical. In one, consciousness resonates within itself; in the other, it is expressing itself.

Both are two phases of the same consciousness—unstruck is silent Brahman, struck is manifested Brahman. When the conscious mind transcends struck vibration and reaches the level of unstruck nada, then sound and silence become one, and humans realize that eternal truth—consciousness itself is sound, sound itself is consciousness.

Nadayoga is such a profound practice of Indian yoga and Tantrashasta, where by taking sound or nada as the medium, one returns to consciousness's primordial source. The word "nada" means resonance, sound, or vibration, and "yoga" means union or oneness. Thus "Nadayoga" literally means becoming one with consciousness's sound-stream—where the seeker gradually progresses from the sounds of the external world toward the silent unstruck nada of the inner world, and merges with that resonance of consciousness.
