Its central claim: the individual self ( jīva ) and the ultimate reality ( Brahman ) are not two different things. The appearance of separation is the root of all suffering, and the recognition of non-separation is liberation. The Central Claim Advaita means non-dual — a (not) + dvaita (two). Vedanta means the end or culmination of the Vedas — the Upanishads. Advaita Vedanta is the school that reads the Upanishads as teaching, without exception, that reality is non-dual. The central claim is not that the world does not exist. Not that the individual person is a delusion to be dismissed. The claim is that the deepest nature of the individual self — the bare awareness by which you know you exist — is identical with Brahman, the ground of all existence. The Mahāvākyas express this from four angles: Prajñānam Brahma (consciousness is Brahman), Aham Brahmāsmi (I am Brahman), Tat Tvam Asi (that thou art), Ayam Ātmā Brahma (this self is Brahman). The school was systematised by Ādi Śaṅkarācārya (c. 788–820 CE), who wrote bhāṣyas (commentaries) on the ten principal Upanishads, the Bhagavad Gītā, and the Brahmasūtras — the three texts that constitute the canonical basis of all Vedanta. Before Śaṅkara, the non-dual tradition was present in the Upanishads themselves and in Gauḍapāda's Māṇḍūkya Kārikā. Śaṅkara gave it a complete philosophical architecture. Key Concepts ब्रह्म Brahman — the ground of all existence Sat-Cit-Ānanda. Not a god who created the world and stands apart from it. The very being-consciousness-fullness that is the ground of everything. आत्मन् Ātman — the self Not the ego, not the personality. The witnessing awareness present through all states of consciousness — waking, dream, deep sleep — unchanged. माया Māyā — the veil The power by which Brahman appears as many — by which the non-dual ground appears as a world of separate objects. Not illusion in the sense of unreality. मोक्ष Mokṣa — liberation Not a destination after death. The recognition, possible now, that the self was never bound — that bondage was always a misidentification, not a fact. नेति नेति Neti Neti — the method Not this, not this. The systematic negation of every inadequate description of Brahman until the mind rests in what no description can capture. साक्षिन् Sākṣī — the witness The pure awareness that witnesses all states — body, thoughts, emotions, the three states of consciousness — without being any of them or affected by them. The Three Vedanta Schools All three schools accept the same three canonical texts (Upanishads, Bhagavad Gītā, Brahmasūtras) as their authority. They disagree on what those texts teach about the relationship between the individual self, the world, and Brahman. Advaita — Non-dual Ādi Śaṅkarācārya (c. 788–820 CE) Brahman alone is real. The individual self and Brahman are identical. The world of multiplicity is Brahman appearing through māyā. Liberation is recognition of this identity — possible in this life. Viśiṣṭādvaita — Qualified non-dual Rāmānuja (c. 1017–1137 CE) Brahman is one, but qualified — individual souls and the world are real as the body of Brahman. The soul retains its identity even in liberation, which is eternal proximity to a personal God (Viṣṇu/Nārāyaṇa). Dvaita — Dual Madhvācārya (c. 1238–1317 CE) Brahman (God), individual souls, and the world are eternally and absolutely distinct. Liberation is the soul's eternal beatific enjoyment of God's presence — never merging with God. → Full comparison: Advaita vs Viśiṣṭādvaita vs Dvaita The Method of Inquiry Advaita's method is jñāna — knowledge, direct recognition — as the sole means of liberation. But this knowledge is not arrived at by accumulating information. The Advaita tradition describes a threefold preparation for the recognition: Śravaṇa — hearing the teaching from the teacher. The Mahāvākyas heard from one who knows. This is the first step: exposure to the pointing statement. Manana — reflection. The student tests the teaching against every objection they can raise, resolving doubts through reasoning. Nididhyāsana — deep contemplation, assimilation. The teaching is absorbed until it is no longer a thought about the self but a recognition of the self. The three steps are not a timeline. For some students the recognition occurs during śravaṇa. For others, years of manana and nididhyāsana are required first. Before these three steps is the preparation described in Vivekacūḍāmaṇi: viveka (discrimination between the real and the unreal), vairāgya (dispassion toward all that is impermanent), śamādi ṣaṭka sampatti (sixfold inner wealth: calm, restraint, withdrawal, endurance, concentration, faith), and mumukṣutva (the burning desire for liberation). These are not prerequisites that must be perfected before inquiry can begin — they are the qualities that deepen through inquiry. The System in Full Advaita Vedanta is the most fully developed and most widely influential of the Vedanta schools — the philosophical tradition reading the Upanishads, Bhagavad Gītā, and Brahmasūtras as consistently pointing at one non-dual reality (Brahman) as the ultimate nature of everything. The word Advaita means "not-two" — the systematic claim that the apparent multiplicity of the world and the apparent individuality of the self are both appearances within the one undivided consciousness that is Brahman. The system was given its definitive form by Śaṅkarācārya (c. 788–820 CE), building on Gauḍapāda (c. 6th–7th century CE). The system's core argument: both the world and the individual self are genuine appearances within the one Brahman — not illusions (they are genuinely appearing) but not independently real realities (they do not exist outside Brahman). The Vedantic inquiry — śravaṇa, manana, nididhyāsana — dissolves the appearance of s --- *Cite as: "Advaita Vedanta — The Complete System — Advaita & Upanishads Codex", Advaita & Upanishads Codex, https://thecodex.expert/advaita/advaita-vedanta/, last updated 2026-04-27.* *Part of [Advaita & Upanishads Codex](https://thecodex.expert/advaita) — a LUDIFU knowledge project.*
