Important Philosophers of India
Adi Shankaracharya (Shankara)
Historical Background
Adi Shankaracharya lived in the 8th century CE and is regarded as one of the greatest philosophers of India. He was born in Kaladi in present-day Kerala.
He belonged to the tradition of Advaita Vedanta, which is one of the most influential philosophical systems in Hindu thought.
At a time when Buddhism, Jainism, and different Hindu sects were actively debating philosophical ideas, Shankaracharya emerged as a powerful intellectual voice. His mission was not merely academic; it was civilizational—to reinterpret and consolidate Vedic philosophy.
After taking Sanyasa (renunciation) at a young age, he travelled across India undertaking Digvijaya, meaning philosophical conquest of the four directions. During these journeys, he engaged in debates with scholars of various traditions and established the supremacy of Advaita Vedanta.
Major Intellectual Contributions
Commentaries on Sacred Texts
One of Shankaracharya’s greatest contributions was writing authoritative commentaries (Bhashyas) on foundational Hindu scriptures.
These include → Brahma Sutras, Principal Upanishads, Bhagavad Gita
These three together are known as the Prasthanatrayi (three foundational texts of Vedanta philosophy).
Through his commentaries, Shankaracharya systematically explained Vedantic philosophy, making it intellectually rigorous and accessible.
Criticism: “Buddhist in Disguise”
Some opponents criticised Shankaracharya as a “Buddhist in disguise.”
Why?
Because certain elements of Advaita Vedanta, especially the idea that the world is illusory, appear similar to Buddhist philosophical concepts such as Shunyavada.
However, there is a crucial difference:
- Buddhism denies a permanent self.
- Advaita Vedanta asserts that Atman (self) is identical with Brahman.
Thus, although there are similarities, the philosophical foundations differ.
Institutional and Religious Contributions
Shankaracharya’s role was not only philosophical but also organizational. He reorganised Hindu traditions to create unity among various sects.
(1) Dashanami Sampradaya
He established the Dashanami Sampradaya, a monastic order for Hindu monks.
“Dashanami” literally means ten names. Monks were organised into ten traditional titles such as → Giri, Puri, Bharati, Tirtha, Saraswati, Vana, Aranya, Parvata, Sagara, Ashrama
This created a structured monastic tradition within Hinduism.
(2) Panchayatana Worship
Shankaracharya introduced the Panchayatana form of worship, which involves the simultaneous worship of five major deities:
| Deity | Representation |
| Ganesha | Remover of obstacles |
| Surya | Sun god |
| Vishnu | Preserver |
| Shiva | Destroyer |
| Devi | Divine feminine power |
The philosophical idea behind this system is important: All deities are different manifestations of one supreme reality — Brahman.
Thus, Panchayatana worship promoted religious harmony among different sects while allowing devotees to worship their Ishta Devata (chosen deity).
(3) Shanmata System
Shankaracharya also popularised Shanmata, meaning six paths of worship.
| Sect | Main Deity |
| Shaivism | Shiva |
| Vaishnavism | Vishnu |
| Shaktism | Devi |
| Saurism | Surya |
| Ganapatya | Ganesha |
| Kaumaram | Kartikeya (Murugan) |
The idea behind Shanmata was spiritual inclusiveness. Instead of sectarian conflicts, Shankaracharya emphasised that all these paths ultimately lead to the same ultimate reality.
(4) Establishment of Four Cardinal Maths
One of his most enduring contributions was establishing four monastic centres (Maths) across India.
| Math | Location | Direction |
| Sringeri Sharada Peeth | Karnataka | South |
| Govardhan Math | Puri (Odisha) | East |
| Sharada Math | Dwarka (Gujarat) | West |
| Jyotirmath | Badrinath (Uttarakhand) | North |
These Maths played a crucial role in:
- preserving Vedantic scholarship
- spreading Advaita philosophy
- maintaining spiritual continuity across India
In many ways, these institutions helped create a pan-Indian philosophical network.
Philosophy of Advaita Vedanta
The central idea of Shankaracharya’s philosophy is Advaita, which means Non-Dualism.
Advaita asserts that reality is ultimately one, and any perceived difference is due to ignorance.
Let us understand its key concepts.
(1) Brahman – The Ultimate Reality
According to Advaita Vedanta:
- Brahman is the only absolute reality.
- It is infinite, eternal, and beyond attributes.
Everything else is a temporary appearance.
(2) Atman = Brahman
Shankaracharya famously asserted: Atman (individual soul) is identical with Brahman (universal reality).
This is expressed through the Upanishadic Mahavakya → “Tat Tvam Asi” — Thou art That.
This means the essence of the individual self is not separate from the ultimate cosmic reality.
(3) Maya – The Illusory Nature of the World
If everything is Brahman, why do we see diversity?
Shankaracharya explains this through the concept of Maya.
- Maya is the cosmic illusion that creates the appearance of multiplicity.
- Due to ignorance (Avidya), we perceive the world as separate and fragmented.
A common analogy used in Vedanta: Mistaking a rope for a snake in darkness.
The snake appears real until knowledge reveals the truth.
(4) Moksha – Liberation
The ultimate goal of human life is Moksha (liberation).
According to Shankaracharya:
- Liberation occurs when one realises the unity of Atman and Brahman.
- It is achieved by removing ignorance (Avidya) through knowledge.
This liberation is not reaching somewhere, but realising one’s true nature.
(5) Jnana Yoga – Path of Knowledge
Shankaracharya emphasised Jnana Yoga, the path of knowledge.
This involves:
- Study of scriptures
- Self-inquiry
- Meditation
- Guidance from a guru
Important texts for this path include → Upanishads, Bhagavad Gita, Brahma Sutras
Influence on Indian Thought
The impact of Shankaracharya on Indian civilisation is enormous.
His contributions include:
- Systematising Vedanta philosophy
- Revitalising Vedic traditions
- Promoting religious unity
- Establishing monastic institutions
- Influencing later philosophical schools
Even today, Advaita Vedanta remains one of the most influential philosophical systems in India and the world.
Statue of Adi Shankaracharya
A modern tribute to Shankaracharya is the 108-foot ‘Statue of Oneness’ located at Omkareshwar in Madhya Pradesh.
Important geographical context:
- It stands on Mandhata Island on the Narmada River.
- The island houses Omkareshwar and Amareshwar, two important Jyotirlinga temples.
- The island itself resembles the sacred syllable “Om”, from which the name Omkareshwar is derived.
✅ In essence:
Adi Shankaracharya was not just a philosopher but a civilizational reformer who intellectually unified Hindu traditions through Advaita Vedanta, institutional reforms, and inclusive worship systems.
Now let us move to Ramanujacharya, another towering philosopher of Indian thought. If Shankaracharya represents pure non-dualism (Advaita), Ramanuja offers a more devotional and theistic interpretation of Vedanta called Vishishtadvaita (Qualified Non-Dualism). Understanding this difference is crucial because it explains the philosophical diversity within Vedanta itself.
Ramanuja (Ramanujacharya)
Historical Background
Ramanuja (Ramanujacharya) lived in the 11th–12th century CE and is regarded as one of the most influential philosophers of the Sri Vaishnavism tradition within Hinduism.
- Birthplace: Sriperumbudur (Tamil Nadu)
- Birth: Into a Brahmin family during the Chola period
- Major centre of activity: Srirangam temple, one of the most important Vaishnavite pilgrimage centres in India.
Ramanuja emerged in a period when Vedantic philosophy had already been strongly shaped by Adi Shankaracharya’s Advaita Vedanta. However, Ramanuja felt that Advaita’s concept of the world as illusion (Maya) did not adequately explain the devotional relationship between God and the devotee.
Thus, he developed an alternative interpretation of Vedanta called Vishishtadvaita.
Ramanuja’s Place in Vedanta Philosophy
Within Vedanta, three major philosophical schools developed:
| Philosopher | School | Core Idea |
| Adi Shankaracharya | Advaita Vedanta | Absolute non-dualism |
| Ramanujacharya | Vishishtadvaita Vedanta | Qualified non-dualism |
| Madhvacharya | Dvaita Vedanta | Dualism |
Ramanuja’s philosophy therefore occupies a middle position between the complete non-dualism of Shankara and the strict dualism of Madhva.
Philosophy of Vishishtadvaita
- Advaita → Non-dualism
- Vishishta → Qualified / with attributes
Thus Vishishtadvaita means “qualified non-dualism.”
Ramanuja accepted that ultimate reality is one, but he argued that this unity includes real distinctions.
In simple terms → The universe and individual souls are distinct but inseparable from Brahman.
Key Philosophical Ideas
1. Vishnu as the Supreme Reality
For Ramanuja, the ultimate reality Brahman is not an abstract principle but a personal God.
This supreme being is Vishnu (or Narayana).
Thus:
- Brahman = Vishnu
- Vishnu is the creator, sustainer, and ultimate controller of the universe.
This personal concept of God became central to Vaishnavite devotional traditions.
2. Qualified Non-Dualism
Ramanuja rejected the strict monism of Advaita Vedanta.
According to him:
- Individual souls (Atman) are real.
- The material world (Prakriti) is also real.
However, both are dependent on Brahman.
He explained their relationship through a famous analogy
→ The universe is like the body, and Brahman (Vishnu) is the soul.
Just as the body cannot exist independently of the soul, the universe cannot exist independently of Brahman.
Thus, they are distinct, yet inseparable
3. Reality of Individual Souls (Jivas)
Ramanuja emphasised that individual souls are eternal.
Key points:
- Souls are distinct entities
- They possess individual identity
- But they depend on Brahman for their existence
Thus, unlike Advaita:
- The soul does not lose its individuality after liberation.
4. The Material World is Real
This is a major difference from Shankaracharya.
Shankaracharya → World is Maya (illusion)
Ramanuja → World is real and meaningful
Ramanuja believed:
- The material universe is God’s creation
- It serves as the body of God
Therefore the world is not illusory, but a divine manifestation helping the soul progress spiritually.
5. Moksha (Liberation)
In Advaita Vedanta, liberation means merging into Brahman. Ramanuja interpreted liberation differently.
For him: Moksha is the eternal blissful union with Vishnu, not the dissolution of individuality.
The liberated soul resides in Vaikuntha, the divine abode of Vishnu.
Thus liberation means:
- Freedom from rebirth
- Eternal devotion to Vishnu
- Blissful communion with God
6. Bhakti as the Path to Liberation
Ramanuja strongly emphasised Bhakti (devotion).
According to him: The most effective path to liberation is → Worship, Prayer, Devotion, Service to God. Thus spiritual realisation is not merely intellectual knowledge, but loving devotion to Vishnu.
This idea later became extremely important in the Bhakti Movement across India.
7. Importance of Divine Grace (Kripa)
Another crucial idea in Ramanuja’s philosophy is Kripa (divine grace). He believed: Liberation ultimately depends on God’s grace, not just human effort.
Therefore, the devotee must practice complete surrender to Vishnu.
This surrender is known as Prapatti (total surrender to God)
Through humility and devotion, the devotee receives divine grace, which leads to liberation.
Influence of Ramanuja
Ramanuja’s impact on Indian religious traditions was profound.
His teachings:
- Strengthened Vaishnavism
- Promoted devotional worship of Vishnu
- Influenced temple traditions in South India
- Inspired Bhakti saints and devotional literature.
His philosophy also helped spread the worship of Vishnu’s avatars, especially Rama and Krishna. Thus Ramanuja played a crucial role in shaping devotional Hinduism.
Statue of Equality (Ramanuja Statue)
In modern times, Ramanuja has been commemorated through the Statue of Equality.
Key facts:
- Located at Muchintal near Hyderabad (Telangana)
- Height: 216 feet
- Unveiled in 2022
The statue symbolises Ramanuja’s message of Equality, Devotion and Spiritual inclusiveness
✅ In summary:
Ramanujacharya transformed Vedanta by introducing a theistic and devotional interpretation through Vishishtadvaita, where:
- God is personal (Vishnu)
- The world and souls are real
- Liberation is achieved through Bhakti and divine grace.
Let us now move to the third major philosopher discussed in Vedanta traditions — Chaitanya Mahaprabhu. If Shankaracharya represents the path of knowledge (Jnana) and Ramanuja emphasises devotion with philosophical structure, Chaitanya Mahaprabhu represents the emotional and ecstatic culmination of Bhakti. His teachings profoundly shaped devotional Hinduism, especially Krishna devotion.
Chaitanya Mahaprabhu
Historical Background
Chaitanya Mahaprabhu was a 16th-century Hindu saint from Bengal and the founder of Gaudiya Vaishnavism.
Key aspects of his life:
- Born in 1486 CE in Navadvipa (present-day West Bengal)
- Lived during the late medieval Bhakti movement
- Became one of the most influential proponents of Krishna devotion
Chaitanya Mahaprabhu’s spiritual mission focused on spreading Bhakti (devotion) to Krishna, particularly through collective singing and chanting of God’s name.
His devotional approach was simple yet powerful — instead of complex rituals or philosophical debates, he emphasised direct emotional connection with God.
Founder of Gaudiya Vaishnavism
Chaitanya Mahaprabhu established the tradition known as Gaudiya Vaishnavism.
- “Gaudiya” refers to the Gauda region of Bengal.
- It is a Krishna-centric devotional tradition within Vaishnavism.
This tradition strongly emphasises:
- Devotion to Krishna
- The divine love between Radha and Krishna
- Spiritual practice through chanting and singing
Contributions to the Bhakti Movement
Chaitanya Mahaprabhu made several important contributions to devotional practices:
1. Propagation of Bhakti Yoga
He promoted Bhakti Yoga as the most accessible path to spiritual liberation.
2. Sankirtan Movement
He popularised Sankirtan, which means congregational chanting of God’s name.Devotees gather together and chant devotional hymns, especially the Hare Krishna Maha-mantra.
3. Hare Krishna Maha-mantra
The mantra he promoted became globally famous:
Hare Krishna Hare Krishna
Krishna Krishna Hare Hare
Hare Rama Hare Rama
Rama Rama Hare Hare
According to Chaitanya, chanting the divine name purifies the mind and connects the soul with God.
4. Shikshashtakam
Chaitanya Mahaprabhu composed the Shikshashtakam, a set of eight devotional prayers that summarise the essence of Bhakti.
Philosophy of Chaitanya Mahaprabhu
Acintya Bheda Abheda
The central philosophy taught by Chaitanya Mahaprabhu is Acintya Bheda Abheda.
Breaking down the term:
- Acintya → Inconceivable
- Bheda → Difference
- Abheda → Non-difference
Thus the philosophy means: “Inconceivable simultaneous oneness and difference.”
According to this doctrine:
- The individual soul and God (Krishna) are simultaneously one and different.
- This relationship cannot be fully understood by human logic — it is beyond intellectual reasoning.
Key Features of His Philosophy
1. Krishna as the Supreme Deity
Chaitanya Mahaprabhu regarded Krishna as the Supreme God.
He taught that:
- Krishna is the source of all creation
- All other forms of divinity originate from Krishna.
Thus, devotion to Krishna is considered the highest spiritual path.
2. Simultaneous Oneness and Difference
According to Chaitanya’s philosophy:
- The soul originates from God. Therefore it shares divine nature
However, the soul remains distinct from God
Thus:
- There is unity (spiritual origin)
- There is difference (individual identity)
This paradoxical relationship is described as Acintya (inconceivable).
3. Importance of Bhakti and Sankirtan
Chaitanya emphasised Bhakti as the central spiritual path.
But he gave special importance to Sankirtan, which involves:
- Congregational chanting
- Singing devotional hymns
- Dancing in spiritual ecstasy
Through Sankirtan, devotees experience direct emotional connection with Krishna.
This method made spirituality accessible to ordinary people, regardless of caste or scholarly knowledge.
4. Radha-Krishna Devotion
A unique feature of Chaitanya’s teachings is the emphasis on Radha-Krishna divine love.
He believed that the purest form of devotion is reflected in the love between Radha and Krishna.
In this spiritual symbolism:
- Krishna represents the supreme divine
- Radha represents the soul’s highest devotion
Thus the relationship between the soul and God is compared to the love of a devotee for the beloved divine.
5. Prema Bhakti – Pure Love for God
For Chaitanya Mahaprabhu, the ultimate spiritual goal is Prema Bhakti.
This means → Pure, Selfless, Unconditional love for God
Prema Bhakti leads to → Spiritual liberation and Eternal union with Krishna
Unlike intellectual paths, this devotion is expressed through emotion, surrender, and love.
Influence of Chaitanya Mahaprabhu
Chaitanya’s teachings had a profound influence on devotional traditions.
His contributions include:
- Popularising Krishna Bhakti
- Transforming devotional practices through Sankirtan
- Inspiring devotional literature and music
- Influencing later Vaishnava traditions
His ideas eventually spread worldwide through the Hare Krishna Movement.
ISKCON (International Society for Krishna Consciousness)
A major modern organisation inspired by Chaitanya’s teachings is ISKCON, also known as the Hare Krishna Movement.
Key Facts
- Founded in 1966
- Founder: A. C. Bhaktivedanta Swami Prabhupada
- Founded in New York City
- Headquarters: Mayapur, West Bengal
ISKCON belongs to the Gaudiya Vaishnava tradition established by Chaitanya Mahaprabhu.
