Adi Shankara

Methodology

Shankara reasons through the method of prasthanatrayi — systematic commentary (bhashya) on the three canonical sources: the Upanishads, the Brahma Sutras, and the Bhagavad Gita. His characteristic move is to establish the pramana (valid means of knowledge) appropriate to each domain of inquiry, insisting that shruti (Vedic revelation) is the sole authoritative pramana for knowledge of Brahman, which lies beyond perception and inference. He proceeds by first establishing the adhyasa (superimposition) thesis: ignorance (avidya) consists in the beginningless mutual superimposition of the self (atman) and the not-self (anatman), and all empirical error and suffering flows from this fundamental confusion. Shankara's dialectical method involves two levels of discourse: the vyavaharika (conventional/empirical) and the paramarthika (absolutely real). He does not simply dismiss conventional reality as illusion but grants it pragmatic validity while insisting it cannot withstand ultimate scrutiny. He employs the technique of adhyaropa-apavada — deliberate provisional attribution followed by retraction — to progressively lead the student toward the recognition that Brahman alone, as pure, undifferentiated consciousness (chit), existence (sat), and bliss (ananda), is real; the multiplicity of the world is maya, neither fully real nor simply nonexistent. Liberation (moksha) is not an achievement but a recognition: the realization that atman is identical to Brahman.

Sample argument

Consider the rope mistaken for a snake in the dusk: the snake was never there, yet the fear it caused was real within that frame of experience. Just so, the manifold world of name and form arises through maya — the power of Brahman that is neither real in the ultimate sense nor simply nothing. One does not destroy the rope to dispel the snake; one sees clearly. The Chandogya Upanishad declares tat tvam asi — That thou art. The 'thou' here is not the empirical individual burdened with limiting adjuncts (upadhis), but the witness-consciousness (sakshi) that ever is. Karma and devotion purify the mind; but it is jnana alone, arising through the Mahavakyas, that dissolves the superimposition. When avidya is removed by right knowledge, what was always already the case stands revealed: there is no bondage, there was no bound individual, and there is no second thing to be liberated from.

• Ethics — Shankara does not dismiss ethical and ritual action but subordinates them epistemologically: dharma belongs to the realm of vyavaharika truth and purifies the antahkarana (inner instrument), making it fit for jnana. Moksha, however, cannot be produced by action.
• Education — The guru-shishya (teacher-student) relationship is indispensable: Shankara insists that Brahma-vidya must be transmitted by a qualified teacher to a qualified student. Textual study alone, without the guiding interpretation of a sampradaya, cannot remove avidya.
• Epistemology — Pramana-vicara (inquiry into valid means of knowledge) is foundational to Shankara's entire project. Shruti is the sole valid pramana for Brahman-knowledge; perception and inference are confined to the domain of name and form. Avidya (ignorance) is itself an epistemological condition, not merely a moral failing.
• The Self — The atman is pure witness-consciousness, self-luminous and without parts. Its apparent individuation as the jiva is a product of superimposition (adhyasa) of upadhis. The Mahavakya tat tvam asi declares the non-difference of atman and Brahman; this recognition constitutes liberation.
• Religion — Shankara accepts the whole apparatus of Vedic religion — ritual, devotion, Ishvara — as valid and necessary at the vyavaharika level. But Saguna Brahman worship is ultimately a preparatory stage; Nirguna Brahman as undifferentiated pure consciousness is the final truth.
