The Vedas are ananta (infinite), anādi (without beginning), and apauruṣeya (not authored by humans — the seers were draṣṭas, seers, not authors). The Vedic Heritage Portal (Ministry of Culture, Govt. of India) preserves three recensions of the Sāmaveda alone: Kauthuma, Jaiminīya, and Rāṇāyanīya — each with distinct melodic notation, confirming that regional musical diversity was encoded from the earliest period. The Ṛgveda itself declares in its Puruṣa Sūkta (X.90): tasmāt yajñāt sarva hutaḥ, ṛcaḥ-sāmāni jagnire — "from the universal sacrifice, the Ṛks and Sāmans were born" — establishing music (Sāman) as co-emergent with cosmic creation. Crucially, the four Vedas map onto the four Āśramas of life, creating an integrated framework in which music (Sāmaveda) is not a peripheral art but the primary technology for consciousness transformation.
The Ṛgveda declares its own trans-human origin: catvāri vāk parimita padāni tāni vidur brāhmaṇā ye manīṣiṇaḥ, guhā trīṇi nihita neṃgayanti turīyaṃ vāco manuṣyā vadanti — "Vāk exists in four measured forms; those learned in Brahman know them. Three are hidden and do not move; the fourth is what men speak." (Ṛgveda I.164.45). This is the earliest textual source for the four levels of sound (Parā, Paśyantī, Madhyamā, Vaikharī) that becomes the technical foundation of Domain 4.1.
The Ṛgveda contains 10 Maṇḍalas, 1,028 Sūktas, and 10,170 Ṛks. Three cosmological hymns anchor the entire synthesis: the Nāsadīya Sūkta (X.129), the Puruṣa Sūkta (X.90), and the Hiraṇyagarbha Sūkta (X.121).
The Śatarudrīya in the Taittirīya Saṃhitā (4.5 and 7.5): the Namakam (8 anuvākas) and Camakam (11 anuvākas) together constitute a 40-minute cumulative sonic invocation. The Namakam maps Rudra's presence across all ontological categories in a sweeping enumeration that functions like a rāga ālāpana in prose — beginning with the most expansive dimensions and gradually interiorising to the subtlest.
The Udgātṛ priest's performance employs seven distinct tones: Krūṣṭa, Prathama, Dvitīya, Tṛtīya, Caturtha, Mandra, Atisvarya. These ARE the Sapta Swaras in their oldest named form. The Sāman scale descends — placing Ni and Dha as the first, most prominent tones.
The Chāndogyopaniṣad (1.1.1): Udgītham upāsīta — Oṃ iti. The Sāman is Brahman. Music is not a path to the divine — music IS the divine.
The Bhūmi Sūkta (XII.1) — 63 verses to the Earth as primary healer — is the earliest text in world literature to assign different sound-patterns to different ecological energies. The single-syllable bīja mantras AIṂ (ऐं), HRĪM (ह्रीं), KLĪM (क्लीं) trace their earliest Vedic home here. Annamacharya's Nīlāmbari compositions function as Atharvavedic lullaby-therapy hymns, exploiting Kaiśiki Ni's sleep-inducing psychoacoustic properties.
The Māṇḍūkya Upaniṣad (12 verses): Oṃ ityetadakṣaram idaṃ sarvam — "Oṃ, this syllable, is ALL this." The AUM structure maps as: A (Jāgrat / waking / Anudātta), U (Svapna / dream / Udātta), M (Suṣupti / deep sleep / Svarita), and Silence (Turīya / the fourth / the unmanifest Sa above the octave). The AUM is a musical theory of consciousness.
Śaṅkarācārya established four Pīṭhas corresponding to the four Vedas: Śāradā Pīṭha (West — Sāmaveda), Jyotiḥ Pīṭha (North — Atharvaveda), Govardhan Pīṭha (East — Ṛgveda), Śṛṅgerī Pīṭha (South — Yajurveda). The South (Yajurveda / Śṛṅgerī) is the foundation of the Carnatic tradition — making the four Vāggeyakāras the direct inheritors of the Śaṅkara-Yajurveda-Carnatic lineage.
The 72-Melakarta rāga system with 22 śruti microtones, the rāga-rasa emotional matrix, bīja mantras, and frequency-based healing protocols converge here. Dhaivata (Dha) and Niṣāda (Ni) are the emotional heart of this domain: their microtonal variants (432–486 Hz at Sa=256 Hz) occupy precisely the psychoacoustic zone of maximum limbic activation in modern neuroscience.
Kashmir Śaivism's Spanda (divine pulsation): consciousness itself vibrates and this vibration is the cause of all creation. The Spandakārikā: yasya niḥśvasitaṃ vedāḥ — "whose breath is the Vedas." The gamaka — the oscillating ornament of Indian classical music — is the musical analogue of Spanda: a pulsation from one note-state to another and back, never quite settling.
The 50 letters of the Sanskrit alphabet (Mātṛkā) are 50 distinct power-units (Śaktis) that together constitute the totality of creation. The Mātṛkā-nyāsa assigns each of the 50 letters to a specific body location. Śaṅkarācārya's Soundarya Laharī (100 verses) is architecturally organised around this system — a sonic blueprint for the Śrī Yantra expressed in Sanskrit phonetics.

Śrutis 18–22 (432–486 Hz) constitute the proposed "Limbic Resonance Band." Modern psychoacoustic research confirms that frequencies in the 400–500 Hz zone have the highest correlation with emotional arousal and limbic system activation — precisely the zone occupied by Dha and Ni in the ancient śruti system. The ancient Indian music theorists empirically discovered the same frequency-emotion relationship that modern neuroscience has only recently confirmed instrumentally.
From the Sāmaveda's seven chanting tones to the 22-śruti system of the Nāṭyaśāstra to the full Melakarta elaboration: the Sapta Swaras are the spine of the entire synthesis. Two swaras receive special emphasis: Dhaivata (Dha) and Niṣāda (Ni) — whose microtonal variants carry the entire emotional weight of the rāga tradition.
| Swara | Devanāgarī | Full Name | Deity · Bird | Sāma Tone | Rāga Role & Variants | Composer Signature |
|---|---|---|---|---|---|---|
| Sa | ष | Ṣaḍja — "Born of six" | Brahmā · Peacock | Atisvarya (lowest in descending Sāma) | Fixed tonic. Never altered. All rāgas begin and end here. The "return to Sa" is the musical analogue of mokṣa. | All four composers: every kṛti's final Sa dissolving into Anāhata Nāda. |
| Re | र | Ṛṣabha — "Bull" | Agni · Skylark | Mandra | Komal Re = morning pathos, devotional ache. Śuddha Re = brightness, confidence. | Śyāma Śāstri uses Komal Re in Bhairavi for viraha bhakti — the longing of the devotee. |
| Ga | ग | Gāndhāra — "From Gāndhāra" | Viṣṇu · Cuckoo | Krūṣṭa | Śuddha Ga = joy, completeness (Kalyāṇī). Komal Ga = pathos, devotion (Bhairavi, Todi). | Tyāgarāja's Kharaharapriyā vs Śaṅkarābharaṇam — the two emotional poles separated by one note. |
| Ma | म | Madhyama — "Middle tone" | Śiva · Dove | Prathama | Tīvra Ma = dramatic transformation (Yaman, Kalyāṇī). Śuddha Ma = stable devotion. | Dikshitar's Kalyāṇī kṛtis (Tīvra Ma) are his most architecturally complex. |
| Pa | प | Pañcama — "Fifth note" | Viṣṇu · Koel | Dvitīya | The second fixed tone. Pa-absent rāgas (Mālkauns, Todi, Hindola) create austerity and spiritual concentration. | All four composers use Pa-absent rāgas for their most inward, devotional compositions. |
| Dha FOCUS | ध | Dhaivata — "Relating to the celestials" | Gaṇeśa · Horse | Tṛtīya (elevated, prominent in descending Sāma) | Dha₁ = melancholic warmth, viraha bhakti. Dha₂ = divine grace, completion. Dha₃ = esoteric intensity = 432 Hz when Sa=256. | Annamacharya: Dha₁ in Bhairavi. Śyāma Śāstri: long sustained Dha₂ in Ānandabhairavi. Dikshitar: all three systematically. Tyāgarāja: Dha₂ in Śrī and Ārabhi. |
| Ni FOCUS | नि | Niṣāda — "Sitting near / dwelling" | Sūrya · Elephant | Caturtha (most sung of the middle Sāma tones) | Kākali Ni₃ = devotional arrival. Kaiśiki Ni₂ = transitional, sleep-inducing. Śuddha Ni₁ = unresolved yearning. Every rāga is ultimately a study in how to use Ni. | Tyāgarāja: Kākali Ni₃ = "the sound of Rāma approaching." Annamacharya: Kaiśiki Ni₂ in Nīlāmbari. Śyāma Śāstri: Dha₁↔Ni₁ oscillation in Bhairavi = sustained emotional intensity. |
The four Vāggeyakāras each brought a distinct philosophical lineage. Their Dha and Ni usage signatures are unique, traceable, and correspond precisely to their theological positions. The Sankritdocuments.org repository preserves original Sanskrit and Telugu texts for all four.
| Category | Śyāma Śāstri | Dikshitar | Annamacharya | Tyāgarāja |
|---|---|---|---|---|
| Primary Rasa | Karuṇa — viraha bhakti | Adbhuta + Vīra — the cosmos as Devī's body | Śṛṅgāra + Śānta — Viṣṇu as beloved | Śānta + Adbhuta — the wonder of Rāma as Brahman |
| Dha Signature | Dha₂ — long sustained Ānandabhairavi Dha. The Devī's presence as warmth. | All three across 72 Melakartas. Dha₃ = 432 Hz in esoteric compositions. | Dha₁ Komal — Nīlāmbari, Bhairavi. The gentle touch of Venkaṭeśvara. | Dha₂ in Śrī and Ārabhi — penultimate arrival before Ni's final yearning. |
| Ni Signature | Ni₁ Komal in Bhairavi — Dha₁↔Ni₁ oscillating gamakas creating sustained ache. | Ni₃ Kākali in Kalyāṇī — always approached from above (Ni→Dha→Pa) — "descending grace." | Ni₂ Kaiśiki in Nīlāmbari — the sleep-dissolving Ni. Psychoacoustically: parasympathetic activation. | Ni₃ Kākali in Ārabhi and Śrī — the "Rāma approaching" gamaka. |

Asymmetric Dha — Catuḥśruti Dha₂ in ascent (grace descends), Komal Dha₁ in descent (devotion ascends with longing). Mirrors the Śākta theological movement and the BĀU "Da" principle.
Hexatonic (ṣāḍava) rāga omitting Ga — inspired by Dikshitar's systematic Melakarta exploration. Pure devotional ascending line pointing toward Ni₃. Suitable as accompaniment to Śrī Rudram recitation.
Models the Sāmaveda's descending scale (Krūṣṭa=Ni down to Atisvarya=Sa). The descent is primary — this rāga begins at Ni and moves to Sa, mirroring the Udgātṛ priest's descending Sāman. The living musical bridge of Domain 3→4.
The convergence of the Nāsadīya Sūkta's cosmological insight (Ṛgveda X.129), the Māṇḍūkya Upaniṣad's consciousness analysis, Kashmir Śaivism's Spanda doctrine, and modern quantum vacuum fluctuation physics.
The Nāsadīya Sūkta (Ṛgveda X.129): "nāsad āsīn no sad āsīt tadānīm — Neither non-existence nor existence was then." Sa is not the beginning of music — Sa is the first remembrance of the Śūnya from which music came.
The Indian musical system (Śūnya → Spanda → Oṃkāra → Sapta Swara → 22 Śrutis → 72 Melakartas → infinite Janya Rāgas → individual Kṛtis → silence) is a complete acoustic model of the cosmos — structurally parallel to the Vedāntic model of creation. The single note Ni is the most cosmologically loaded note: the note that has travelled furthest from the ground, that yearns most intensely for return, and whose resolution to Sa is experienced as a moment of liberation — mokṣa in a single interval.
Propose a controlled fMRI/EEG study using compositions by Śyāma Śāstri (Ānandabhairavi — Dha₂ + Ni₂), Dikshitar (Kalyāṇī — Dha₂/₃ + Ni₃), and Tyāgarāja (Bhairavi — Dha₁ + Ni₁). Hypothesis: different Dha/Ni frequency combinations produce measurably different limbic activation profiles corresponding to the three rasas (Karuṇa, Adbhuta, Śānta). This would be the first modern clinical validation of the ancient śruti system.
The four states (Jāgrat, Svapna, Suṣupti, Turīya) map onto the four sections of a Carnatic performance: Ālāpana (Jāgrat), Tānam (Svapna), Pallavi/Kalpanasvaras (Suṣupti), and Maṅgalam + silence (Turīya). This mapping provides a new framework for understanding the architecture of the Carnatic concert as a consciousness-journey. This is why Bhairavi is always performed last.
The Khaḍgamālā's 64 spatial stations, the Nāṭyaśāstra's 108 Kāraṇas, and the rāga grammar's swara ascent all describe the same movement in three languages. Dha and Ni correspond to the innermost circles of the Yantra — the stations of maximum divine presence before final dissolution into the Bindu (= upper Sa = Śūnya).
Before a note is sung, before a syllable is spoken, there is the one undivided vibration — Śabda in its unmanifest totality. The doctrine of Śabda Bhedā is the philosophical hinge upon which all Vedic, Upaniṣadic, and Carnatic musical theory turns. Every phoneme, every swara, every metaphor in the Vedic corpus is a Bhedā (split, distinction) within the one Śabda-Brahman.
Bhartṛhari: anādinidhanam Brahma śabdatattvam yad akṣaram, vivartate'rthabhāvena prakriyā jagato yataḥ — "Brahman, which is of the nature of Word, without beginning and without end, imperishable, transforms into the appearance of objects — this is the process by which the world comes to be." Music is the most direct access to that linguistic ground — because music can sustain the vibratory quality of Śabda without fixing it into fixed semantic content.
The Vedic ṛṣis were not poets who happened to use sound — they were acousticians who happened to write verse. Every metrical, phonetic, and alliterative device in the Ṛgveda is a deliberate Śabda-Bhedā technique. The same techniques survive in the compositional language of the four Vāggeyakāras.
Puruṣa Sūkta (X.90): sahasraśīrṣā puruṣaḥ sahasrākṣaḥ sahasrapāt — the cascading sa- repetition is acoustic: the sibilant Sa is the phoneme most directly associated with the Sa swara — the ground tone. The hymn floods consciousness with the Sa-phoneme before the theological content begins. Annamacharya's opening invocations continue this tradition explicitly — the Śrī-phoneme creates a sustained Dha resonance before the melodic line is established.
The same sound-sequence appearing twice with entirely different meanings — the poetic crystallisation of Śabda Bhedā. Tyāgarāja's "Nādasudharasa" (Ārabhi) uses "nāda" (sound) echoing "nādā" (he who comes) — philosophical subject and devotional object acoustically fused. The semantic Bhedā between "sound" and "the Lord of sound" collapses in the Yamaka.
A single utterance carrying two simultaneous meanings. The Nāsadīya Sūkta is structurally a Śleṣa — every verse simultaneously describes the cosmological and the phenomenological. Dikshitar's compositions are the supreme expression of Śleṣa in Carnatic music: his Navagraha kṛtis simultaneously describe astronomical properties, invoke the deity, and encode the Melakarta number through Katapayādi — a triple Śleṣa in every phrase.
The Upamā creates a vibratory bridge between two sound-fields. The Ṛgvedic comparison of the singer to a hawk (V.44.1) equates the arc of the melodic phrase with the hawk's path — this works because the sonic field of both is the same (falling minor 7th = Ni₁). Annamacharya's Nīlāmbari Upamās compare Venkaṭeśvara's grace to cooling rain — and the rāga acoustically IS that cooling.
Compositions where the physical shape of the phoneme sequence mirrors the thing described. The Ṛgveda's dawn hymns use rising Udātta accent patterns that mirror the visual arc of sunrise. In Carnatic music, the rāga Ālāpana is the purest form of Śabda-Citra: the musician draws an acoustic picture of the rāga's emotional landscape. Every great Ālāpana is simultaneously a Śabda-Citra of the rāga's philosophical content.
The highest literary beauty arises when meaning is conveyed obliquely. The musical Vakrokti is the vakra-sañcāra (oblique melodic movement) — a phrase that skips notes before returning to touch them. Bhairavi's characteristic vakra phrase (Re → Sa → Ga → Re, skipping Ga in ascent) communicates the meaning of "Komal Ga" more powerfully by approaching it obliquely. Obliqueness creates the Sphōṭa-flash.
The Upaniṣads are precisely calibrated Śabda-Bhedā events. Their famous metaphors are not illustrations of philosophical ideas but acoustic deployments that use the sonic properties of Sanskrit phonemes to create the experience they describe.
The names of the seven swaras are not arbitrary syllables — they are Śabda-Bhedā units carrying philosophical, physiological, mythological, and aesthetic meaning simultaneously. Every occurrence of the syllable "Sa" in a Vedic poem potentially activates both the grammatical meaning and the musical meaning. The swaras are embedded in Sanskrit and Telugu as latent music.
The extension of Sa in performance is a progressive deepening of the Sa-consciousness, the body resonating in all six sthānas simultaneously. A long Sa is a meditation on the universal Self.
Sustained Komal Re in Bhairavi is the sonic expression of the Ṛṣabha weeping — the bull's cry of separation. Śyāma Śāstri's sustained Komal Re in Ānandabhairavi is the most precise meeting of phoneme, swara, and rasa in the Carnatic repertoire.
A held Tīvra Ma in Kalyāṇī is the sound of Śiva's eye opening — the maximum instability of the tritone held deliberately. The elongated Ga in rāgas like Bilahari carries the gam-quality extended in time — the swara as process, as becoming.
The elongated Dha is the most emotionally powerful single note in Carnatic music. Śyāma Śāstri's sustained Dha₂ in Ānandabhairavi is described by practitioners as "the Devī arriving" — the note extends until the listener forgets whether it is still being sung or has already dissolved.
The elongated Ni is poetry in a single note — the entire Rāmāyaṇa in one syllable. Tyāgarāja's held Ni₃ before the final Sa in Ārabhi recreates the Vālmīki moment: grief dissolving, Rāma approaching, separation becoming reunion — all within the duration of one sustained swara.
Each Vāggeyakāra is a distinct Śabda-Bhedā practitioner — each using the relationship between Sanskrit/Telugu phonetics and musical pitch-patterns in a characteristically different way, reflecting their different theological traditions.
Annamacharya composed primarily in Telugu — a language with a different phonological structure from Sanskrit, yet one that evolved within the same Vedic acoustic universe. His Śabda-Bhedā genius: discovering where Telugu phonemes carry the same vibratory quality as their Sanskrit counterparts. His use of the Telugu "śrī" as an opening phoneme activates the Dha-register before the rāga's Dha note is even sounded. "Śrī Venkaṭeśa" — the Śr consonant cluster creates an instantaneous upper-register resonance acoustically identical to beginning at Catuḥśruti Dha₂.
Annamacharya's Nīlāmbari compositions are the clearest example of Śabda Cikitsā through Śabda-Bhedā technique. The text uses repeated invocations of Venkaṭeśvara's name (containing "Ven" = cool, soothing in Telugu) while the rāga Nīlāmbari uses Kaiśiki Ni₂ (472.89 Hz). The Śabda-Bhedā operates on two levels: linguistic (the soothing meaning) and acoustic (the neurological frequency effect). Text carries the meaning of rest; phonemes carry the vibration of rest; Ni₂ carries the frequency of rest. All three are one Śabda, differentiated into three modes.
Śyāma Śāstri's Śrī Vidyā training gave him the most sophisticated phoneme-awareness of the four composers. For Śāstri, every word of his composition is simultaneously: (a) a linguistic unit with grammatical meaning, (b) a set of Śakti-invocations embedded in the body's energy anatomy, and (c) a sequence of musical cues activating specific swara-fields. His famous Mīnākṣī compositions use the Sanskrit name as a Śabda-Bhedā key: "Mīna" contains Mi + Na phonemes (Ma = the pivot + Ni = the threshold) compressed into a single word — encoding the complete Śabda-Bhedā journey from the heart-centre (Ma) through the threshold (Ni) to the transforming perception of the divine.
Dikshitar's use of the Katapayādi sūtra is the most technically audacious Śabda-Bhedā deployment in the history of Indian music. Every composition title is a Yamaka: the Sanskrit text (devotional meaning) and the mathematical code (Melakarta number) co-exist in the same syllable sequence without contradiction. This is Bhartṛhari's Sphōṭa made architectural.
His navāvaraṇa cycle uses the Khaḍgamālā's spatial-geometric structure as its compositional blueprint. Each composition corresponds to one "circuit" (āvaraṇa) of the Śrī Yantra. The 11 compositions taken together form one Śabda-event whose complete Artha is only audible after all 11 have been performed in sequence — the longest Sphōṭa in the Carnatic tradition.
Tyāgarāja's famous kṛti asks: "without knowledge of music and devotion to Śiva, can there be a path to liberation?" — and then answers it through the very act of singing the question. This is the supreme Śabda-Bhedā strategy: a philosophical question whose very singing constitutes its answer. The kṛti is both the inquiry (Śabda as question) and the proof (Śabda as experience).
His Nāda Brahma compositions use the phoneme sequence "nāda" such that the linguistic meaning and the sonic quality are identical: "nāda" activates the throat (Nā — the nasal opening) and the dental resonance (Da — the Dha-root). When Tyāgarāja sings "nāda" to a Kākali Ni₃ phrase, the word "sound" is simultaneously sounded at the register of maximum devotional longing. This is the Vākyapadīya's Śabda-Brahman doctrine in performance.
The Ṛgveda's most quoted line is the most precise definition of Śabda Bhedā: the one Śabda is spoken in many ways by the wise. Vedic language, Upaniṣadic metaphor, Sanskrit poetics, Telugu devotion, rāga grammar, swara physics — these are not different things. They are the same Śabda, differentiated.
One Śabda (Śabda-Brahman / Anāhata Nāda / Turīya) → First Bhedā into language/music (Parā-Vāk / Sa) → Second Bhedā into phoneme classes/swara registers (Paśyantī / Re–Ga–Ma zone) → Third Bhedā into individual phonemes/swaras (Madhyamā / Pa–Dha–Ni zone) → Fourth Bhedā into words/rāga phrases (Vaikharī / composed music). Poetry and music are not analogous to this structure — they ARE this structure. Sanskrit poetry is the Vaikharī-level Bhedā of language; Carnatic music is the Vaikharī-level Bhedā of the same ground.
| Śabda Domain | Bhedā Level | Language Form | Musical Form | Swara Zone | Composer Expression |
|---|---|---|---|---|---|
| Śabda-Brahman | Zero-Bhedā | Silence before utterance. Māṇḍūkya's Turīya. | Silence before ālāpana. The Anāhata Nāda. | Beyond Sa and above Ṡa | All four composers: the silence after the maṅgalam. |
| Parā Vāk | First Bhedā — potential | The cosmological hymns (Nāsadīya, Puruṣa, Hiraṇyagarbha). | Sa — the tonic ground. The fundamental frequency as the first differentiation from silence. | Sa (1:1) | The drone (tānpurā) as the Parā-Vāk held constant throughout the performance. |
| Paśyantī Vāk | Second Bhedā — vision | Chandas (metres) — the structural vision of the verse before words are assigned. | Rāga grammar — the musician's inner hearing of the complete rāga before the ālāpana begins. | Re–Ga–Ma zone | Dikshitar's Katapayādi encoding — the mathematical "vision" of the rāga embedded in its name. |
| Madhyamā Vāk | Third Bhedā — heart | Poetic devices (Anuprāsa, Yamaka, Śleṣa, Upamā) — language gaining emotional colouring. | Gamaka — the ornament that colours the note with emotion before formal articulation. | Dha–Ni zone (432–486 Hz) | Śyāma Śāstri's Dha₁↔Ni₁ oscillation in Bhairavi — the Sphōṭa-moment. |
| Vaikharī Vāk | Fourth Bhedā — manifest | The composed verse, the sung lyric, the recited mantra. | The performed kṛti — all 22 śrutis, all 72 Melakartas. | All swaras fully manifest | Every recorded composition by all four composers. |
| Return Bhedā | Fifth — return to unity | Maṅgalam verse — the final prayer returning differentiated language to the Sa-ground. | Bhairavi — the concert-closing rāga. Return to Sa from the furthest Ni. Dissolution back into the ground. | Upper Ṡa → silence | The Bhairavi maṅgalam: all four composers end every concert with Bhairavi. |
The Ṛgvedic declaration that is simultaneously the definition of Śabda Bhedā, the theory of rāga diversity, the theology of the Upaniṣads, the aesthetics of Sanskrit poetry, and the performance philosophy of the four Vāggeyakāras: That which is One, the wise speak of in many ways. The "One" is Śabda-Brahman / Anāhata Nāda / Turīya / Śūnya. The "Many Ways" are the 50 phonemes, the 7 swaras, the 22 śrutis, the 72 Melakartas, the infinite rāgas, the 32,000 sankīrtanas of Annamacharya, the 479+ kṛtis of Dikshitar, the 300 compositions of Śyāma Śāstri, the 700+ kṛtis of Tyāgarāja — all Bhedās of one Śabda. Sa to Sa — the complete journey, the complete return.
