Adi Shankaracharya

Adi Shankaracharya’s intellectual project unified a wide scholastic landscape into a coherent articulation of nondual Vedānta. His commentaries—the Brahma‑Sūtra‑Bhāṣya, the Bhagavad‑Gītā‑Bhāṣya, and exegeses on the Īśa, Kena, Kaṭha, Praśna, Muṇḍaka, Māṇḍūkya (with Gauḍapāda’s Kārikā), Taittirīya, and Bṛhadāraṇyaka Upaniṣads—set benchmarks for philological care and systematic argument. The doctrine of adhyāsa (cognitive superimposition) frames how ignorance (avidyā) projects limitation and plurality upon indivisible Brahman, producing the entanglement of ‘I’ and ‘mine’. Instruction proceeds through ‘neti‑neti’ (not this, not this), a disciplined negation that discloses the self as pure awareness rather than body, sense, or mind. Mahāvākyas—tat tvam asi, ahaṃ brahmāsmi—are treated as precise pedagogical pointers, enacted through listening (śravaṇa), reflection (manana), and contemplative assimilation (nididhyāsana). Shankara’s hermeneutics safeguards a double vision: the world is pragmatically real for ethics and ritual (vyāvahārika‑sattā) yet ultimately dependent in the light of nondual Brahman (pāramārthika‑sattā). This distinction allows both ordinary responsibilities and uncompromising nonduality to stand. His engagements with Mīmāṃsā, early Vaiṣṇava and Śaiva thought, and later Rāmānuja’s and Madhva’s schools gave Indian philosophy much of its classical contour. Institutionally, digvijaya narratives describe travels and debates as well as the founding or systematizing of four maṭhas—Śṛṅgeri, Dvārakā, Puri, and Jyotirmaṭh—each with successor lineages that preserved study, liturgy, and public instruction. Historians read these accounts critically, but the social fact remains: a network of centers carried Advaita into public life, training monks and serving householders through discourses and handbooks. Stylistically, Shankara writes with economy and grace, weaving grammar, logic, and scripture into a pedagogy ordered to liberation (mokṣa) within ordinary life. Disputed attributions such as Vivekacūḍāmaṇi and Ātma‑bodha—whether by him or early Advaitins—translate subtle doctrine into accessible practice. In modern reception, Advaita’s vocabulary has conversed with global philosophy, psychology, and contemplative science; translations proliferate; and Shankara Jayanti anchors communal study. Beyond debates over dates or hagiography, the enduring gift is a grammar of freedom that ties textual reasoning to direct insight and an institutional ecology that keeps that inquiry alive.
