Hindu dharma: A civilization of immanent debate, reform, and assimilation

By Dr. P.K. Gupta* 

The tapestry of Hindu Dharma is not woven from a single thread but from countless strands of philosophical inquiry, spiritual seeking, and cultural exchange that have accumulated over millennia. Unlike many religious traditions that trace their origins to a single prophet or sacred text, Hinduism has evolved as a living civilization, continuously shaped by debate, reform, and the remarkable capacity to assimilate new ideas while preserving its essential character.

Perhaps no single event better illustrates this tradition of intellectual openness than the legendary debate between Adi Shankaracharya and Mandana Mishra in 800 AD. For forty-two days, these two towering intellects engaged in a verbal duel representing opposing schools of thought, yet their contest remained free from malice and violence. When Mandana Mishra was defeated, he voluntarily converted to Shankaracharya's Dvaita Vedanta philosophy—a testament to the persuasive power of ideas and the willingness of Indian religious traditions to embrace new understandings. This spirit of reasoned discourse would continue to shape Hindu thought for centuries.

The Bhakti movement, which swept across South India from the seventh to tenth centuries and later spread to the North and East between the fifteenth and seventeenth centuries, established new theological interpretations and social reforms as an integral part of dharma's continuing evolution. These devotional movements advocated for knowledge and devotion accessible to all followers regardless of caste, challenging entrenched hierarchies and ritualistic practices. The Bhakti saints taught that divine love transcended social boundaries, and their teachings resonated deeply with the common people.

Even the Mughal court, often remembered for its Islamic orthodoxy, witnessed remarkable religious debates. On February 28, 1580, at Akbar's court in Agra, invited Jesuits from Goa engaged in debate with Muslim scholars, during which the Prophet Muhammad was questioned and the Quran's validity challenged. The Jesuits' aim was to convert Akbar to Christianity, yet the emperor tolerated this open defiance to Islam, demonstrating his commitment to intellectual inquiry and religious pluralism.

Hindu Dharma has always been a churning ocean of philosophical ideas, drawing from the hundreds of dharma traditions practiced since the Indus Valley civilization. It has never been restrained to one God, one book, one way of life, or one singular thought. Differing and deviating philosophies were initially resisted, but when alternative perspectives were understood, they were gradually assimilated into the broader Hindu tradition. The Lingayats in 1100 AD, the nineteenth-century Brahmo Samaj, Arya Samaj, and Narayan Swami sects all advocated opposition to ritualism and oppressive caste practices. With time, these amendments to dharma became accepted and normalized.

Social reform movements often met with fierce opposition before achieving acceptance. The prohibition of Sati in 1829, led by evangelist William Carey and Hindu reformer Ram Mohan Roy, criminalized the practice. Conservative Hindus, led by the knighted Radhakanta Deb and his Dharma Sabha, opposed the ban and attempted to revive Sati, but they ultimately lost their case before the Privy Council in 1832, resulting in even stiffer punishments for the practice. Similarly, the Hindu Women's Rights to Property Act of 1937, which granted widows property rights, was an early step toward the comprehensive Hindu Code Bill. When the consolidated code was first proposed in the Constituent Assembly in 1946, Purshotam Das Tandon opposed it, perceiving it as an attempt to annihilate dharma. Yet eight decades later, these codes are fully accepted and assimilated into the constitution.

The history of religious conversion in India reveals a complex pattern of voluntary adoption, mutual influence, and cultural synthesis. One Vedic shloka describes the Asura—the indigenous peoples of the Indian subcontinent—as those who do not give credence to the Vedas, do not worship the thirty-three Devatas, and worship the Linga. Yet in subsequent centuries, Linga worship was universally adopted by all Hindus, and Asura and Vedic traditions learned from each other, laying the foundations of what would become Sanatan Dharma. The Ikshvaku, Jains, and Buddhists rejected animal sacrifice, varna, varga, and caste distinctions, yet these traditions coexisted and influenced one another.

When Buddhism declined in India, Sanatana adopted Buddhist literature and the idols of monasteries, converting them into its own tradition. In 800 AD, Adi Shankaracharya converted the Varanasi Pandits to his Advaita philosophy, leading to the reestablishment of Sanatan Dharma. Every reform proposed by religious teachers was met with resistance from significant numbers of orthodox believers, yet both perspectives coexisted and survived side by side for centuries—a testament to the pluralistic nature of Hindu civilization.

Voluntary conversion has been a consistent feature of Indian religious history. Heliodoros, the Greek ambassador, converted to Sanatan Dharma in 113 BC, as inscribed on a stone pillar near Sanchi. The apostles of Jesus—St. Thomas in Kerala in 52 AD and St. Bartholomew in Mumbai in 55 AD—reached Indian shores, and high-caste Nayars and Ayyar Brahmins converted to Christianity. Muslims arrived as Arab traders in Malabar in the seventh century, and the first mosque outside Mecca was established in Kerala during the lifetime of Prophet Muhammad. With the conquest of Sindh by Mir Kassim in the seventh century, Islam arrived in India, and trade protection combined with the decline of indigenous religions led to continuous conversion in Afghanistan, Baluchistan, and Sindh.

Sufi influence in Punjab since the tenth century attracted people to Islam, and Khwaja Moinuddin Chisti's followers began converting at Ajmer in 1190. The Sufi missionary Shah Sultan Rumi influenced the local ruler and population of Netrokona in Bengal to embrace Islam in 1053. Kashmir became Muslim under the influence of Central Asia between the twelfth and thirteenth centuries, and Sufi missionaries influenced people to convert, eventually leading to the decline of Shaivism in the valley. In the Gangetic plains, Islam spread after the defeat of Prithvi Raj Chauhan III at the Second Battle of Tarain in 1192.

The religious landscape of India also witnessed the emergence of new sects and movements. Ravidas (1267-1335) preached that the soul in the human body is a particle of God that cannot be rejected on caste basis, opposing inequality and advocating communal harmony. The Ravidassiya sect was born and has been recognized as a separate religion since 2009. Kabir (1440-1518) propagated the concept of Nirgun God, challenging established Sanatan traditions, and the oppressed populace joined the Kabirpanthi sect. Sikhism began replacing Sanatan traditions in Punjab from 1500 AD, and Hindu idols were removed from the Golden Temple in 1905.

Throughout these transformations, dual religious believers maintained their original faith while adopting new doctrines. The Mohyal Brahmins of the Dutt clan, who fought on behalf of Imam al-Hussain at the Battle of Karbala in 680 CE, continue to observe Muharram and keep both the Quran and the Gita in their places of worship to this day. Jains have intermarried with Hindu Vaishya communities for centuries, and Sufi saints are revered by Sikhs, Hindus, and Muslims alike. In Uttarakhand, Himachal Pradesh, and parts of Jammu and Kashmir, people practice the ancient Ponn religion alongside Hinduism. Ladakh and Tibetan Buddhists practice Bon alongside Buddhism, and the seventeenth Dalai Lama has accepted Bon as part of Tibetan Buddhism.

The resilience of this pluralistic tradition is evident in the continued practice of multiple Dera sects in Punjab, Haryana, and Himachal, which promote the teachings of Sikh Gurus and Sanatan traditions. By 2025, amalgamated Deras have become popular, where Christianity, Sikhism, and Hinduism are practiced together. In Ladakh, Shia-Buddhist marriages are common, while in the South, Christian-Hindu-Islamic marriages are frequent, with spouses practicing their own faiths. The Thar Desert's Manganiyars, who are Muslim folk musicians, perform at temples and marriages, and the Mirasi Muslims of Punjab sang Gurbani in Gurudwaras under the patronage of the Sikh Empire. The Bishnois of Rajasthan practice their environmental faith alongside Hinduism.

Many temples in Tamil Nadu, Kerala, Bengal, and Punjab revere Muslim saints. At the Ayappa Temple, a visit to the Vavar Mosque is mandatory during the forty-one-day pilgrimage. The Bonbibi temple in the Sundarbans, Haji Ratan and Ratan Baba at Bhatinda—worshiped by both Muslims and the Gorakh Nath sect—all testify to the fluid boundaries between religious traditions. The story of Abdur Rahim Khan-i-Khanan, a commander in Akbar's army, a Brij dialect poet, a devout Muslim, and a Krishna devotee, captures the essence of this syncretic culture.

Even during periods of religious conflict, acts of respect and cooperation occurred. Prithvi Raj Chauhan III permitted Khwaja Moinuddin Chisti to use Anasagar Lake and settle in Ajmer before his defeat in 1192. Akbar issued coins in the name of Allah and Ram. After the Battle of Panipat III in 1761, Shuja Ud Daulla paid for the dead bodies of Maratha soldiers from Ahmad Shah Abdali so that last rites could be performed according to Hindu rituals under Brahmin supervision. When 22,000 Maratha soldiers were taken as prisoners and given as slaves to the ruler of Baluchistan, they were distributed among Baloch tribes, adopted Islam, and eventually received equal citizen rights in independent Pakistan.

The Mughal period also witnessed remarkable acts of religious patronage. Aurangzeb granted funds for the construction of the Mahakaal Temple in Ujjain, Jhanda Sahib Gurudwara in Dehradun, Balaji Temple in Chitrakoot, the Umananda Island Temple in Guwahati, and the Jain Temple Shatrunjaya in Gujarat. Pundit Ki Mosque in Varanasi was built on land donated by the head priest of Varanasi. Dara Shikoh, the eldest son of Shah Jahan, translated the Upanishads into Persian and the Quran into Urdu. Following Aurangzeb's death in 1707, Sahuji Chatrapati Maharaj constructed a memorial mosque in Satara. In 1755, the land for Hanuman Garhi Temple in Ayodhya was donated by Safdarjung and Avadh Nawab Shuja-ud-Daula.

This remarkable tradition of assimilation continues into the present day. KK Mhammad resurrected eighty Shiva Bateshwar Temples in the Chambal Valley, restoring them to their original 800 AD glory from their seven-hundred-year-old rubble near Gwalior between 2005 and 2026. The dual religious identity, the coexistence of multiple traditions, and the spirit of debate and reform that characterized Hindu civilization from its inception remain alive today. Nepal's 2011 census introduced eleven tribal religions to help people identify themselves in consonance with their beliefs, while India's census in 2011 abolished the Adivasi religion column, effectively forcing 200 million Adivasi to be classified as Hindu.

Hindu Dharma, as this history demonstrates, is not a static belief system but a dynamic civilization—a vast river fed by countless tributaries, absorbing the waters of diverse traditions while maintaining its essential flow. Its strength lies not in uniformity but in its capacity for debate, reform, and assimilation, in its recognition that truth is multifaceted and that the divine manifests in infinite forms. The civilizations of the Indian subcontinent have long understood that religious identity need not be exclusive, that one can draw from multiple wells of wisdom while remaining rooted in one's own tradition. It is this profound insight that continues to make Hindu Dharma a living, breathing civilization rather than merely a religion.
