Advaita Vedanta is one of the most influential sub-schools of Vedanta, a Hindu philosophical tradition focused on the interpretation of the Upanishads. Advaita, meaning "non-duality," teaches that the individual self (Atman) is identical with the ultimate reality (Brahman), and the perception of difference is due to ignorance (avidya).
Core Principles
Non-Dualism (Advaita)
The fundamental principle of Advaita Vedanta is that reality is non-dual. According to this philosophy:
- Brahman is the only truth
- The world, as we perceive it, is an illusion (maya)
- The individual soul (jivatman) is not different from Brahman
- The experience of duality and multiplicity is due to ignorance (avidya)
Levels of Reality
Advaita recognizes three levels of reality:
- Paramarthika (Absolute Reality) - The unchanging, eternal Brahman; the only true reality
- Vyavaharika (Empirical Reality) - The world of everyday experience, which has practical utility but is ontologically unreal
- Pratibhasika (Illusory Reality) - Hallucinations, dreams, and misperceptions that are subjectively real but objectively false
Maya and Avidya
- Maya is the cosmic illusion that creates the appearance of multiplicity from the non-dual Brahman
- Avidya is individual ignorance that causes one to misapprehend reality and identify with the body-mind complex
Historical Development
Origins and Early Development
While advaitic ideas can be found in the Upanishads, Advaita Vedanta as a systematic philosophy was primarily formulated by Adi Shankaracharya (788-820 CE). Building on the work of his predecessors like Gaudapada, Shankara established Advaita as one of the most influential schools of Hindu philosophy.

Philosophical Framework
Epistemology
Advaita recognizes six pramanas (valid means of knowledge):
- Pratyaksha (perception)
- Anumana (inference)
- Upamana (comparison)
- Arthapatti (postulation)
- Anupalabdhi (non-apprehension)
- Shabda (testimony) - particularly the Vedas and other authoritative texts
Theory of Existence
- Satkaaryavaada - The effect pre-exists in the cause
- Vivartavada - The world is an apparent manifestation of Brahman, like a rope mistaken for a snake
Key Concepts
- Sat-chit-ananda - Being-consciousness-bliss, the nature of Brahman and true Self
- Neti neti - "Not this, not this," the negative method of defining Brahman
- Tat tvam asi - "That thou art," one of the Mahavakyas (great statements) indicating identity of Atman and Brahman
Path to Liberation
The Four Qualifications (Sadhana Chatushtaya)
Prerequisites for pursuing spiritual knowledge:
- Viveka - Discrimination between the eternal and transient
- Vairagya - Dispassion toward worldly objects
- Shatsampatti - Six virtues (mind control, sense restraint, etc.)
- Mumukshutva - Intense desire for liberation
Three Steps to Enlightenment
- Shravana - Listening to the teachings of a qualified guru
- Manana - Reflecting and contemplating on these teachings
- Nididhyasana - Meditation on the truth until direct realization
Jivan Mukti
Advaita teaches that liberation (moksha) can be attained while still living in the body. The Jivan Mukta (liberated while alive) lives free from identification with the body-mind complex, experiencing the unity of all existence.
