India’s Great Religious Conversation
Buddhism, Jainism, Śaivism, Vaiṣṇavism and Vedānta from the Pallavas to Rāmānuja
When we speak of Ādi Śaṅkarācārya and Śrī Rāmānujācārya, it is tempting to place them opposite each other—as though one appeared, established his philosophy, and was followed later by the other.
History is much more interesting.
Both Ācāryas lived in an India already filled with temples, monasteries, philosophical schools, devotional movements and competing ideas about God, the soul and liberation.
Buddhism and Jainism had been present for centuries. Śaivism and Vaiṣṇavism were developing powerful devotional traditions. Sanskrit philosophical debate was flourishing. In the Tamil country, the Nāyaṉmārs and Āḻvārs had already transformed religious expression by bringing intense personal devotion into the lives of ordinary people.
And all this was taking place under different kingdoms—the Pallavas, Pāṇḍyas, Chalukyas, Rashtrakutas, Cholas and, later, Hoysalas and Kakatiyas.
This was not one straight religious story.
It was a great conversation.
The political map was constantly changing
There was no single “South Indian kingdom” during this period.
The Pallavas, with Kanchipuram as their great centre, were important in the earlier development of temple culture and Sanskrit and Tamil learning.
The Pāṇḍyas were centred around Madurai and contributed to the religious and cultural development of the far south.
The Chalukyas controlled important parts of the Deccan through different branches, while the Rashtrakutas became a major power in western and central Deccan.
Then came the extraordinary expansion of the Cholas from the ninth century onward.
And the story did not end there. The Hoysalas became important in Karnataka, while the Kakatiyas rose to prominence in the Telugu-speaking Deccan.
Each kingdom had its own political interests, but religion was deeply woven into society, art, education, agriculture and royal patronage.
Before Śaṅkara: a crowded spiritual landscape
Long before Śaṅkara, India already possessed several major religious and philosophical traditions.
Buddhism
Buddhism had flourished for centuries in different parts of India.
By the early medieval period, however, its strength varied enormously from region to region. In some places it remained important; elsewhere its institutions were declining while Hindu temple traditions were becoming stronger.
Buddhist philosophers had nevertheless contributed enormously to India's intellectual culture.
Questions about the self, consciousness, reality, causation and liberation had become extraordinarily sophisticated.
These questions formed part of the intellectual environment in which Vedānta developed.
Jainism
Jainism had an especially strong presence in parts of Karnataka and Tamil Nadu.
Jain monks, scholars and communities established centres of learning and received patronage from rulers and wealthy donors.
Even under the Cholas, whose major temples were overwhelmingly associated with Śaivism, Jain institutions continued to exist and received patronage in several regions. Inscriptions and surviving monuments provide evidence for Jain establishments in Chola territory.
So the medieval South should not be imagined as a place where one religion simply replaced another overnight.
Different traditions coexisted, competed and sometimes influenced one another.
Then came the great age of Bhakti
Something remarkable was happening in Tamil country.
Religion was no longer expressed only through philosophical texts and ritual institutions.
It was being sung.
The Nāyaṉmārs sang passionately of Śiva.
The Āḻvārs sang passionately of Viṣṇu.
Their Tamil hymns expressed love, surrender, longing, joy and intimate relationship with the Divine.
This was a profound development.
God was no longer only the subject of philosophical discussion.
God could be loved.
The temple became not merely a place where rituals happened, but a living centre around which an entire community could gather.
Śaivism rises with the temple
The medieval South witnessed the extraordinary growth of temple-centred Śaivism.
The Cholas became particularly associated with Śiva worship and constructed some of the most magnificent temples in Indian history.
The great Bṛhadīśvara Temple at Thanjavur, completed under Rājarāja Chola I in 1013, is perhaps the most spectacular example.
The temple was simultaneously a sacred space, an artistic achievement and an expression of royal power.
But even here, the picture was not simply “Cholas versus everyone else.”
Chola rulers and members of the royal family also supported Vaiṣṇava and Jain establishments, and Rājarāja I supported the Buddhist Chūḍāmaṇi Vihāra at Nagapattinam.
The religious landscape was therefore more complicated than dynastic labels suggest.
And Vaiṣṇavism was growing at the same time
While enormous Śaiva temples were being built, the Vaiṣṇava tradition was also becoming increasingly institutionalised.
The 108 Divya Deśams associated with the Āḻvārs provided a sacred geography stretching across the Tamil country and beyond.
At Śrīraṅgam, Tirupati, Kanchipuram, Tirumaliruncholai and many other sacred places, devotion to Viṣṇu took increasingly organised temple form.
The Āḻvārs had given the tradition something extraordinary:
Tamil devotional poetry of immense emotional power.
And this would become extremely important for Rāmānuja.
Where does Śaṅkarācārya fit into this world?
Ādi Śaṅkara belonged to a different stage of this development.
His great concern was philosophical:
What is ultimately real?
The Upaniṣads declared the unity and ultimate reality of Brahman.
Śaṅkara developed a systematic interpretation of the Upaniṣads, Bhagavad Gītā and Brahma Sūtras in which Brahman is the ultimate reality, and liberation comes through knowledge of one's true nature.
The phenomenal world is experienced as real, but ultimate reality is not divided into independent realities.
The individual self, when true knowledge arises, is understood in relation to the non-dual Brahman.
This became the great philosophical system known as Advaita Vedānta.
But Śaṅkara was not operating in an intellectual vacuum.
He was participating in centuries of debate involving Buddhists, Jains, Mīmāṃsakas, Sāṃkhyas, various Vedāntic thinkers and other philosophical schools.
His achievement was to give Advaita an extraordinarily powerful and systematic Vedāntic formulation.
But what about devotion?
This is where the story becomes especially beautiful.
It would be wrong to imagine Śaṅkara's India as purely philosophical and Rāmānuja's India as purely devotional.
Bhakti was already flourishing before Rāmānuja.
And Rāmānuja did not invent Vaiṣṇava devotion.
The Āḻvārs had already sung of Viṣṇu centuries earlier.
What Rāmānuja did was something different and enormous:
He brought philosophy and devotion together into a systematic Vedāntic vision.
Rāmānuja: when philosophy embraces the personal God
By the time Rāmānuja appeared, the South Indian religious landscape had become deeply temple-centred.
Śaiva and Vaiṣṇava traditions were flourishing.
The Cholas were building extraordinary temples.
Jainism remained important in parts of the Deccan and South India.
Buddhism continued in particular centres, although its overall position in much of South India had weakened.
And the Tamil Vaiṣṇava devotional heritage of the Āḻvārs was already immensely rich.
Rāmānuja inherited all of this.
His great question was:
Could the Supreme Brahman of the Upaniṣads be the very personal Nārāyaṇa whom the Āḻvārs loved?
His answer was yes.
Viśiṣṭādvaita
Rāmānuja's philosophy, Viśiṣṭādvaita, taught that Brahman is one, but that this unity does not require us to deny the reality of the individual soul or the universe.
God is Nārāyaṇa.
The individual souls are real.
The universe is real.
Yet neither soul nor universe exists independently of God.
They have an inseparable relationship with Him.
This allowed Rāmānuja to unite two streams that might otherwise appear very different:
the profound philosophical language of the Upaniṣads
and
the intimate devotional language of the Āḻvārs.
The God whom the philosopher seeks is the God whom the devotee loves.
The Cholas and Rāmānuja
Rāmānuja's life unfolded during the great Chola period, when Śaivism had enormous royal and temple prominence.
There are traditional accounts of conflict between Rāmānuja and a Chola ruler, and later Vaiṣṇava hagiographies describe persecution that led to Rāmānuja's departure for the Hoysala kingdom.
However, historians differ over the identification of the ruler involved and the precise historical circumstances. The dramatic later accounts should therefore be distinguished from what can be established securely from contemporary evidence.
What is certain is that Rāmānuja spent an important part of his life in Karnataka, where the Hoysala kingdom provided an important setting for the further development of his tradition.
The association of King Viṣṇuvardhana with Rāmānuja and the great Vaiṣṇava centre of Melukote became an important part of Sri Vaishnava history.
The Hoysala and Deccan world
The story therefore moves beyond Tamil Nadu.
The Chalukyas and later Hoysalas created a religious environment in Karnataka in which Śaivism, Vaiṣṇavism and Jainism all had significant presences.
Chalukya-period evidence shows patronage extending across different religious traditions, including Śaivism, Vaiṣṇavism and Jainism.
This is important because it shows that the history of Indian religion cannot be explained simply by saying:
“One king supported one religion.”
Royal patronage could be multiple.
A ruler might personally favour one deity while granting land or other support to another religious institution.
And the temples were much more than temples
Perhaps this is the part modern readers most easily miss.
The medieval South Indian temple was not simply a building where people went to pray.
It could be a centre of:
worship
education
music
dance
sculpture
food distribution
employment
land management
festivals
charity
local administration
economic exchange
Research on medieval South Indian temples shows how deeply they were integrated into the economic and social life of their communities.
A temple could therefore shape an entire town.
And this helped transform religious traditions from individual beliefs into living civilisations.
What happened to Buddhism and Jainism?
This is where we must avoid another oversimplification.
It is tempting to say:
“Hinduism defeated Buddhism and Jainism.”
The actual history was much more gradual.
Buddhism declined in many parts of India for a variety of reasons—loss of institutional support, changing patterns of patronage, the growth of temple-centred Hindu traditions and the incorporation or transformation of some practices and ideas.
Jainism proved more resilient in several parts of South India, especially Karnataka.
And neither disappeared simply because Śaivism and Vaiṣṇavism grew.
The Chola period itself provides evidence of the continuing presence of Śaiva, Vaiṣṇava, Jain and Buddhist communities and artistic traditions.
So what shaped Śaṅkara and Rāmānuja?
Now we can see the larger picture.
Śaṅkara inherited
the Upaniṣadic tradition
the Brahma Sūtras
a highly developed Sanskrit philosophical culture
centuries of debate with Buddhist and other schools
the emerging strength of Hindu devotional traditions
His response was to establish a powerful vision of non-dual Brahman and liberation through knowledge.
Rāmānuja inherited
the Upaniṣadic and Vedāntic tradition
the Bhagavad Gītā
the Brahma Sūtras
the already ancient Vaiṣṇava tradition
the emotional and theological heritage of the Āḻvārs
an enormous temple culture
a South India where Śaivism, Vaiṣṇavism, Jainism and the remnants of Buddhism were all part of the religious landscape
His response was to show that the personal God of devotion could be the Supreme Brahman of Vedānta.
Not a battle between two men
This is perhaps the most important conclusion.
Śaṅkara and Rāmānuja should not be understood merely as two philosophers arguing with each other across time.
They were products of different moments in a long Indian intellectual and devotional history.
Śaṅkara asked:
What is ultimately real?
Rāmānuja asked:
How can the ultimate Reality be understood as the Lord whom the soul can know, love and surrender to?
Their answers were different.
But both stood within the vast Vedāntic conversation of India.
And behind both stood centuries of religious creativity:
Buddhist monasteries.
Jain scholars.
Upaniṣadic sages.
Śaiva saints.
Vaiṣṇava Āḻvārs.
Temple builders.
Philosophers.
Kings.
Poets.
Ordinary devotees.
India's extraordinary gift
Perhaps the most remarkable feature of this history is that India's religious development was not simply a succession of religions replacing one another.
It was more like a river with many tributaries.
Some became smaller.
Some became enormous.
Some disappeared from particular regions.
Some flowed into new forms.
Some argued fiercely with others.
And yet the arguments themselves produced new philosophy, new poetry, new temples and new ways of understanding the Divine.
From this long civilisational conversation emerged:
Śaṅkara's Advaita — the vision of non-dual Brahman.
Rāmānuja's Viśiṣṭādvaita — the vision of one Supreme Brahman in whom the real universe and real souls have their inseparable existence.
And around both grew the extraordinary temple and devotional culture that still lives today.
This is not merely the story of two Ācāryas.
It is the story of how India thought about God.
And perhaps even more beautifully—
how India learned to think, argue, sing and pray about God at the same time.
