Chapter 73: Regional Sanatan Traditions II: Eastern India, Bengal, Odisha, Assam and the Northeast
How Jagannātha, Manasā, Śākta traditions, Vaiṣṇava bhakti and regional goddess traditions developed through local and wider Sanatan Dharma interactions.
1. Eastern India is a laboratory of religious synthesis
Bengal, Odisha, Assam and neighbouring regions developed some of the most distinctive Sanatan Dharma traditions in South Asia. Their religious worlds combine Sanskritic Purāṇic narratives with regional languages, village cults, river and serpent traditions, goddess worship, Vaiṣṇava devotion and tribal or indigenous religious forms. The historical record repeatedly shows processes of integration rather than a clean boundary between “folk” and “classical.”
2. Jagannātha and Odisha
Jagannātha at Puri is one of the strongest examples of a regional deity becoming a pan-Indian pilgrimage deity. Oxford Bibliographies notes associations of Jagannātha with Vaiṣṇavism, Śāktism, Buddhism and Jainism and emphasizes the role of assimilation and appropriation in the deity's history. Oxford Bibliographies, “Jagannātha”. The wooden form, distinctive siblings Balabhadra and Subhadrā, annual Ratha Yātrā and elaborate temple ritual together produced a religious identity that is unmistakably Odishan and simultaneously transregional.
3. The tribal and local question at Puri
Scholars have discussed possible connections between Jagannātha and non-Sanskritic or tribal traditions, but the exact origin story remains debated. The responsible conclusion is not “Jagannātha is definitely a tribal god” or “Jagannātha has no local component.” Rather, the evidence indicates a deity whose historical identity was formed through multiple layers and later absorbed into increasingly elaborate Vaiṣṇava and Purāṇic frameworks.
4. Manasā in Bengal
Manasā, the serpent goddess, is an unusually clear example of a regional deity entering a broader Sanatan Dharma world. Oxford scholarship describes her as a relatively late entrant to the major Sanatan Dharma pantheon, with roots in earlier religious beliefs, strong regional authority in eastern India, and a major Bengali literary tradition in the maṅgalakāvya. Krishna Datta, “A Goddess from Bengal: Devī Manasā”.
5. Maṅgalakāvya as religious technology
The Bengali maṅgalakāvya poems did more than tell stories. They gave regional goddesses a narrative universe, linked them with Śiva, Ganga and other Purāṇic figures, and created a vernacular devotional literature. A 2025 study argues that texts about Chandi and Manasā illustrate the interaction of “little” and “great” traditions and simultaneous processes of Sanskritisation and parochialisation. “Mangalkavyas and the Acculturation of Medieval Bengal,” 2025.
6. Goddess traditions and women
Eastern Indian goddess worship also demonstrates that ritual authority did not always reside solely in male temple priesthoods. Scholarship on Bengal notes household and neighbourhood women organizing vrata and goddess ceremonies and transmitting narrative traditions. Oxford, “The Goddess–Woman Nexus in Popular Religious Practice”. This is an important reminder that the history of Sanatan Dharma is not only the history of temples and Sanskrit texts.
7. Assam and Śākta traditions
Assam's Kāmākhyā tradition became one of the most important Śākta pilgrimage centres. Its history brings together goddess worship, Tantric practice, regional kingship and pilgrimage. The broader lesson is that regional religious centres can become doctrinally important beyond their original geography. The presence of Tantric practice also warns against reducing Sanatan Dharma to a single ethical or ritual model.
8. Vaiṣṇavism in Assam
Śaṅkaradeva's Vaiṣṇava movement developed a distinctive Assamese religious culture through nāma-kīrtana, monasteries (sattra), performance and vernacular literature. The movement's historical importance lies partly in its ability to create institutions that linked devotional theology, art, music and community organization.
9. Bengal's Śākta-Vaiṣṇava coexistence
Medieval and early modern Bengal cannot be reduced to either Vaiṣṇavism or Śāktism. Chaitanya Vaiṣṇavism, Kali worship, Durga traditions, Manasā and village goddesses coexisted and interacted. Religious identities could be situational: a household might observe multiple festivals and worship different deities without perceiving the practices as mutually exclusive.
10. Ritual forms that connect eastern regions
Common patterns include river bathing, vows, household vrata, seasonal festivals, offerings of cooked food, lamps, flowers, music, narrative recitation, processions and possession or ecstatic devotion. Yet the exact meanings vary. A river ritual in Bengal cannot automatically be equated with a Vedic sacrifice, and a regional goddess festival cannot automatically be classified as Tantric.
11. Islam and regional Sanatan Dharma traditions
Eastern India also provides evidence of shared sacred cultures, shrine visitation and overlapping literary worlds. Such evidence should not be romanticized into “everyone followed the same religion.” Shared practices can coexist with clear doctrinal difference. The historical question is precisely how communities negotiated that difference.
12. Sources and conclusion
The eastern Indian record shows Sanatan Dharma evolving through regional creativity. Jagannātha, Manasā, Chandi, Kāmākhyā and Assamese Vaiṣṇava traditions became important not because a central authority standardized them, but because local communities, poets, rulers, pilgrims and religious specialists continuously reinterpreted them.

13. Language matters
One of the strongest mechanisms of regional religious formation was vernacularization. Sanskrit provided pan-regional theological vocabulary, while Bengali, Odia, Assamese and other languages allowed deities and rituals to become part of household literature, song and performance. A regional deity could therefore gain a wider social base without first becoming linguistically Sanskritic in everyday practice.
14. Pilgrimage creates wider worlds
Pilgrimage connected villages to major centres and converted regional sacred places into nodes of a larger network. Jagannatha's Ratha Yatra is the clearest eastern example, but the same principle appears in goddess pilgrimage, river festivals and Vaishnava circuits. These networks helped turn local stories into shared sacred geographies while preserving local ritual styles.
15. What can be claimed about origins
Origin stories should be separated from historical reconstruction. A community may preserve a respected account of how a deity or shrine began, while scholars may identify multiple stages of development from inscriptions, texts and material evidence. Neither source needs to be dismissed. The appropriate distinction is between a tradition's own account of sacred origins and the historian's reconstruction of institutional development.
16. Performance and material culture
The study of eastern traditions must include performance as well as manuscripts. Kīrtan, theatre, dance, recitation, ritual painting, processions and temple arts can transmit narratives without requiring a written text. Performance also permits variation: the same character can be solemn in one ritual context, comic in another, or radically reinterpreted in a local drama. Anthropological fieldwork is therefore complementary to philology. Neither alone captures the whole religious ecology.
17. Regional language and religious authority
Eastern Indian traditions also show how language can become a source of religious authority. Bengali, Odia and Assamese texts did not simply translate Sanskrit stories word for word. Poets selected episodes, expanded characters, introduced local settings and shaped devotional emotion for particular audiences. The resulting works should therefore be treated as literary and religious creations in their own right. A regional Ramayana or Purāṇic narrative is not merely a corrupted copy of a Sanskrit original; it is evidence of how communities interpreted inherited traditions.
Eastern traditions, vernacular texts and sacred geography
This section strengthens the chapter’s historical method by separating textual evidence, material evidence, later tradition, and modern interpretation. The goal is not to flatten disagreement but to identify what can be established securely, what is plausible, and what remains debated.
Historical method
Eastern India demonstrates particularly well how textual traditions, regional languages, local cults, and political institutions interact. Odisha’s Jagannātha tradition is not adequately explained either as a simple Sanskritic Vaiṣṇava institution or as an unchanged survival of a pre-Brahmanical tribal cult. Historical scholarship instead examines layers of patronage, ritual specialists, temple institutions, regional kingship, pilgrimage, and competing explanations of origin. Similar caution applies to Bengal’s goddess traditions and Assam’s Śākta and Vaiṣṇava histories. The distinction is important because religious traditions are cumulative: later communities frequently preserve older names and stories while giving them new meanings, and modern communities may read ancient texts through categories that did not exist in the same form in antiquity.
Textual and material evidence
The Maṅgalakāvya literature of Bengal is especially important because it shows how religious worlds could be built through vernacular narrative. Stories surrounding Manasā, Caṇḍī and other deities connected household life, commerce, marriage, fertility, danger, disease, and divine power. Such literature was not simply a local substitute for Sanskrit Purāṇas. It was a creative literary field in which inherited mythic materials were reorganized for regional audiences and social concerns. The distinction is important because religious traditions are cumulative: later communities frequently preserve older names and stories while giving them new meanings, and modern communities may read ancient texts through categories that did not exist in the same form in antiquity.
Regional and social variation
Women’s religious practice is also crucial. Vratas, household observances, songs, vows, festival preparations, and goddess worship often preserve forms of religious agency that institutional histories can understate. The study of women’s observances in Sanatan Dharma history has therefore become an important corrective to accounts centered exclusively on male theologians, priests, kings, and monastic leaders. Oxford’s history of Sanatan Dharma practice treats women’s vratas as a distinct field of religious practice rather than merely an appendix to formal theology. The distinction is important because religious traditions are cumulative: later communities frequently preserve older names and stories while giving them new meanings, and modern communities may read ancient texts through categories that did not exist in the same form in antiquity.
Modern reception
Assam provides a contrasting example through the development of Vaiṣṇava institutions associated with Śaṅkaradeva and his successors, alongside Śākta, Śaiva, tribal, and local traditions. The point is not to label one tradition ‘authentic’ and the others derivative. The historical record shows institutional competition, exchange, adaptation, and regional specialization. Religious identities could be layered rather than mutually exclusive. The distinction is important because religious traditions are cumulative: later communities frequently preserve older names and stories while giving them new meanings, and modern communities may read ancient texts through categories that did not exist in the same form in antiquity.
What the evidence allows us to say
Eastern traditions also demonstrate why geography matters. Rivers, wetlands, forests, coastal zones, pilgrimage centers, and agricultural cycles shape religious calendars and sacred narratives. When a deity becomes associated with a particular landscape, that relationship can survive political change and migration. Regional Sanatan Dharma is therefore not only a matter of language; it is also a history of place, ecology, memory, and institutions. The distinction is important because religious traditions are cumulative: later communities frequently preserve older names and stories while giving them new meanings, and modern communities may read ancient texts through categories that did not exist in the same form in antiquity.
Selected scholarly anchors
For further verification, this discussion is anchored in Oxford Academic scholarship and, where relevant, additional Oxford research on Sanatan Dharma history and practice. These sources are used as scholarly reference points rather than as substitutes for primary evidence.
The evidence also cautions against treating eastern India as a peripheral zone. Odisha, Bengal, Assam, and neighboring regions generated influential pilgrimage centers, devotional movements, goddess traditions, literary genres, temple institutions, and philosophical debates. Their histories entered wider Sanatan Dharma networks through pilgrimage and print, while their regional forms continued to retain distinctive ritual and linguistic identities. The resulting picture is one of circulation rather than a simple center-and-periphery model. This additional layer is important because it prevents a common error in civilizational history: treating continuity of vocabulary or mythology as proof that social institutions and practices remained unchanged. Historical continuity can coexist with major transformations in meaning, authority, and practice.
This also explains why regional traditions should be documented through multiple media. A temple inscription may preserve patronage; a vernacular poem may preserve a devotional interpretation; an oral performance may preserve a local genealogy; an archaeological layer may establish the antiquity of occupation; and a colonial report may record a practice while reflecting the observer’s own assumptions. None is automatically superior in every question. Their evidentiary value depends on what historical question is being asked.
This chapter distinguishes three layers whenever possible: the historical evidence, the later community’s interpretation of that evidence, and the modern scholar’s reconstruction. This distinction does not weaken religious tradition; it makes the history more precise. It also prevents modern categories from being projected backward onto periods in which communities organized identity, law, ritual, and sacred geography differently. Where evidence is uncertain, the appropriate conclusion is uncertainty rather than a confident but unsupported reconstruction.
