Advaita Vedanta is one of the most influential schools of Hindu philosophy, propounding a non-dualistic (advaita) interpretation of the Upanishads. The term "Advaita" means "non-dual" or "not two," referring to the idea that the true self (Atman) is identical with the ultimate reality (Brahman). Systematized by the 8th-century philosopher Adi Shankaracharya, Advaita Vedanta continues to be a dominant philosophical framework within Hinduism and has significantly influenced modern Hindu thought.
Core Philosophy
Fundamental Principles
- Non-dualism (Advaita): Reality is ultimately non-dual; Brahman is the only reality
- Identity of Atman and Brahman: The individual self is identical with the ultimate reality
- Maya: The phenomenal world is an appearance or illusion superimposed on Brahman
- Three Levels of Reality:
- Paramarthika (absolute reality): Brahman alone exists
- Vyavaharika (empirical reality): The world as we experience it
- Pratibhasika (illusory reality): Misperceptions like seeing a rope as a snake
Key Concepts
- Nirguna Brahman: Brahman without attributes, beyond all descriptions
- Avidya (Ignorance): The root cause of suffering and the perception of multiplicity
- Jnana (Knowledge): The primary means to liberation, specifically knowledge of one's true nature
- Moksha (Liberation): Freedom from the cycle of rebirth through realization of one's identity with Brahman
Historical Development
Origins and Early Sources
- Upanishadic Roots: Core ideas found in the principal Upanishads
- Brahma Sutras: Systematic presentation of Vedantic thought
- Gaudapada's Karika: Pre-Shankara exposition of Advaita ideas
- Buddhist Influence: Parallels with Madhyamaka and Yogacara Buddhist philosophies
Adi Shankaracharya and Systematization
Adi Shankaracharya (788-820 CE) systematized Advaita Vedanta through:
- Commentaries (Bhashyas) on the Upanishads, Brahma Sutras, and Bhagavad Gita
- Original works like Vivekachudamani and Upadeshasahasri
- Establishment of four monastic centers (mathas) across India
- Development of a lineage of disciples to preserve and propagate the teachings
Post-Shankara Developments
- Vachaspati Mishra (9th century): Bhamati school of Advaita
- Prakashatman (10th century): Vivarana school of Advaita
- Suresvara and Padmapada: Direct disciples who developed aspects of Shankara's thought
- Vidyaranya (14th century): Synthesized various strands of post-Shankara Advaita
Modern Revival
- Neo-Vedanta: Modern interpretations by figures like Swami Vivekananda
- Academic Study: Integration with Western philosophical discourse
- Global Spread: Adoption by spiritual seekers worldwide
- Dialogue with Science: Contemporary discussions about consciousness
Epistemology and Methods of Knowledge
Advaita Vedanta recognizes six pramanas (valid means of knowledge):
- Pratyaksha (Perception): Direct sensory experience
- Anumana (Inference): Logical deduction
- Upamana (Comparison): Understanding something by comparing it to something known
- Arthapatti (Postulation): Assumption of a fact to explain an observation
- Anupalabdhi (Non-apprehension): Knowledge from the absence of something
- Shabda (Testimony): Knowledge from reliable sources, especially the Vedas
Special Importance of Shabda
While acknowledging all six pramanas, Advaita gives special importance to shabda, particularly the Upanishadic statements called "mahavakyas" (great sayings):
- "Tat Tvam Asi" (That Thou Art) - Chandogya Upanishad
- "Aham Brahmasmi" (I am Brahman) - Brihadaranyaka Upanishad
- "Prajnanam Brahma" (Consciousness is Brahman) - Aitareya Upanishad
- "Ayam Atma Brahma" (This Self is Brahman) - Mandukya Upanishad

- Response to Buddhism: Distinction from Buddhist emptiness while incorporating aspects of Buddhist logic
Theory of Error (Khyativada)
- Anirvacaniya Khyati: The appearance of the world is neither real nor unreal but inexplicable
- Rope-Snake Analogy: Mistaking a rope for a snake illustrates how Brahman appears as the world
- Superimposition (Adhyasa): The attribution of unreal qualities to the real
