Assess the statement that 'the philosophy of Shankaracharya revolutionised religious thoughts in India'.

Answer:

Shankaracharya (c. 788-820 CE) restated the Upanishadic tradition as the rigorous monism of Advaita Vedanta and, by combining philosophical argument with practical organisation, decisively reshaped Indian religious thought at a moment when Buddhism was declining and sectarian devotion was rising.

The core of his philosophy

• He taught Advaita, or non-dualism: Brahman alone is real, the world is maya, and the self is Brahman.
• His formula held that Brahman is real, the world illusory, and the individual soul not different from Brahman.
• Knowledge (jnana), not ritual action, was the means to liberation.
• He distinguished empirical (vyavaharika) from absolute (paramarthika) truth to reconcile experience with monism.
• His commentaries on the Upanishads, Brahmasutra and Gita, the prasthanatrayi, gave Vedanta its classical form.

Why it was revolutionary

• It gave Brahmanism a coherent philosophical system able to withstand Buddhist and Jain dialectic.
• It subordinated Vedic ritualism, then dominant as Mimamsa, to the pursuit of knowledge.
• It reasserted the authority of the Vedas while refounding them on reason.
• By absorbing Buddhist logical method, he was accused by opponents of being a crypto-Buddhist.

Organisation and consolidation

• He founded four mathas at Sringeri, Puri, Dwarka and Badrinath, binding the subcontinent together.
• The Dashanami order of monks gave Hinduism a durable monastic structure it had lacked.
• His extensive travels and public debates (shastrartha) spread the doctrine widely.
• He encouraged the worship of five deities (panchayatana) to unify competing sects.

The wider religious impact

• He is credited with hastening the decline of Buddhism by absorbing its strongest arguments.
• His defeat of Mandana Mishra in debate symbolised the subordination of ritualist Mimamsa.
• Advaita became the dominant philosophical idiom of Hinduism for centuries.
• His work gave a common intellectual framework to otherwise diverse sects.

A critical assessment

• Later thinkers challenged him: Ramanuja's qualified monism and Madhva's dualism arose in reaction.
• Bhakti saints held that Advaita's austere abstraction left little room for devotion.
• Its emphasis on renunciation had limited appeal for ordinary householders.
• Critics note he did not challenge caste or ritual practice in social life.
• Yet even his opponents had to define themselves against him, which measures his centrality.

The statement is thus largely justified. Shankara did not merely refine existing ideas but recast them into a system that reoriented Indian philosophy and gave Hinduism both intellectual coherence and institutional strength. As scholars observe, the vitality of the traditions that arose to oppose him is itself the surest evidence of how far his thought transformed the religious landscape.
