Sanatan Dharma Roots/What is Sanatan Dharma

What Was Sanatan Dharma?

Long before religions were classified, named, or compared, the Indian subcontinent had already possessed a complete civilisational system governing life, thought, knowledge, ethics, and spiritual inquiry. This system did not begin with a founder, a proclamation, or a moment of conversion. It existed as a way of living and understanding existence. That system was what later generations called Sanatan Dharma, and what the modern world came to know as Hinduism (Radhakrishnan, 1927; Flood, 1996).

The idea that Hinduism was a recent construction or that Sanatan Dharma was merely a philosophical abstraction was not supported by historical, textual, or archaeological evidence (Thapar, 2002; Witzel, 1995). Both had existed as continuous expressions of the same civilisational tradition since ancient times. The difference lay largely in terminology rather than substance.

In the earliest layers of Indian history, people did not identify themselves through religious labels. They lived according to dharma, a concept encompassing duty, ethical order, social responsibility, and harmony with nature (Olivelle, 1993). This dharma governed agriculture, kingship, family life, ritual practice, learning, and spiritual pursuit.

Sanatan Dharma was understood as the eternal and universal order shaping the philosophical, social, cultural, and spiritual foundations of the Indian subcontinent since antiquity. It was not a historical religion bounded by a founder, fixed doctrine, or single canonical text. Instead, it worked as an lasting civilisational framework expressing principles of right conduct, cosmic balance, ethical responsibility, and liberation (Radhakrishnan, 1927; Flood, 1996). These principles formed the underlying basis of what later came to be called Hinduism. Archaeology, textual studies, comparative linguistics, and historical anthropology all pointed to the deep antiquity and continuity of this tradition (Possehl, 2002; Singh, 2008).

Modern scholarship often classified Hinduism as a family of traditions. However, within the tradition itself, the self-description preserved across Vedic, Itihasa, and Purana literature was Sanatan Dharma, meaning the eternal dharma (Basham, 1954). The term referred to a universal law not confined by temporal or geographical boundaries. Scriptural foundations, archaeological continuities, legal and societal developments, philosophical elaborations, and cross-cultural interactions collectively demonstrated Sanatan Dharma as one of the world’s most continuous civilisational systems.

The Vedas, the oldest surviving textual corpus of India, did not proclaim a new religion. They assumed an already existing order. Fire rituals, hymns to natural forces, philosophical inquiries into existence, and ethical conduct were presented as inherited knowledge rather than innovations (Rigveda; Radhakrishnan, 1927). This continuity extended through the Brāhmaṇas, Āraṇyakas, and Upaniṣads, where ritual action and philosophical reflection coexisted without contradiction (Olivelle, 1996).

What later scholars termed Hinduism had already been present, functioning without the necessity of a formal name.

The term Sanatan Dharma appeared in later texts to describe this enduring order. Sanatan meant eternal or timeless, and dharma denoted that which upheld and sustained cosmic and social harmony (Flood, 1996).

This explained why Indian tradition did not treat its way of life as something that began at a specific historical moment. Kings ruled according to dharma, householders lived by dharma, and seekers pursued liberation through dharma. The continuity of social institutions, ritual systems, philosophical schools, and ethical ideals indicated not a collection of unrelated beliefs but a unified civilisational framework (Thapar, 2002).

The Name “Hindu” in Historical Usage

As this civilisation interacted with neighbouring cultures, names emerged to describe its people and lands. The word Sindhu appeared frequently in the Rigveda as the name of a great river and the surrounding region (Rigveda 10.75). Rivers in Vedic thought were central to economy, ritual, and cosmology.

Within the Indo-Iranian linguistic sphere, a phonetic shift transformed s into h, and thus Sindhu became Hindu in Avestan usage. The Avesta referred to Hapta Hindu, the land of seven rivers, corresponding to the Vedic Sapta Sindhu (Avesta, Vendidad). This usage dated to the second millennium BCE, long before medieval Persian or Arab interactions (Witzel, 1995).

This shift reflected shared linguistic ancestry rather than external imposition.

Classical Sanskrit grammar also recognised phonetic interchange. Pāṇini’s grammatical system described transformations among sounds such as sa and ha under defined rules (Pāṇini, Aṣṭādhyāyī). Vedic textual variants reflected such phonetic flexibility.

Over time, Hindu came to describe people who followed this ancient dharmic system. Indigenous texts did not treat the word as foreign. Later Purāṇic literature used the term Hindu in cultural and ethical contexts (Bhavishya Purāṇa). Biographical traditions associated with Ādi Śaṅkarācārya also referred to followers of Vedic authority and ethical discipline in terms that aligned with the later cultural meaning of Hindu identity (Madhava Digvijaya).

The name Hindustan appeared in early cultural-geographic usage to describe the land stretching from the Himalayas to the southern seas. Persian Achaemenid inscriptions referred to Hidush as a province of the Indus region (Darius Inscription). Chinese pilgrims such as Faxian and Xuanzang recorded phonetic variants of the same name (Beal, 1884).

Within the tradition, being Hindu was associated with conduct rather than ethnicity. Ethical cultivation, knowledge, self-discipline, and social responsibility were central ideals. Terms such as Ārya and Sanātanī were used alongside Hindu as complementary cultural and ethical descriptors (Basham, 1954).

Hinduism did not originate when the word Hindu gained currency. What existed from earliest times was Sanatan Dharma, a self-sustaining civilisational way of life. The modern term Hinduism later served as a convenient label for this ancient and continuous tradition (Flood, 1996)

Conclusion

Sanatan Dharma was not an abstract philosophy detached from history, and Hinduism was not a late construction. They represented the same civilisational tradition viewed through different historical and linguistic lenses. From the earliest Vedic hymns through later philosophical systems, from grammar and ritual to ethics and social organisation, continuity remained evident (Radhakrishnan, 1927; Thapar, 2002).

The notion that Hinduism was created in a later period or imposed by outsiders weakened when examined alongside linguistic, textual, and archaeological evidence. What endured across millennia was Sanatan Dharma — an evolving yet continuous civilisational tradition rooted in knowledge, responsibility, and cultural continuity.
