Thinkers & Authors
Philosophers, poets, novelists, sages — the voices in the conversation.
Indian
Vyāsa
The legendary sage who, Hindu tradition holds, divided the Veda into four, composed the Mahābhārata (in which he is also a character and the grandfather of both warring clans), and wrote the Purāṇas — the archetypal author of Indian tradition.
Uddālaka Āruṇi
Upanishadic teacher who instructed his son Śvetaketu with salt in water and the seed of a banyan, ending each lesson — “tat tvam asi”, that thou art.
Yājñavalkya
The boldest sage of the Upanishads, who taught that the Self (ātman) is the unseen seer, describable only as “neti neti” — not this, not this.
Gārgī Vācaknavī
The woman philosopher who challenged Yājñavalkya at King Janaka’s court with questions about what the universe is “woven on” — pressing him until he warned that her head would fall off, then returning with two questions “like arrows”. One of the earliest named women philosophers in history.
Maitreyī
Yājñavalkya’s wife, “a discourser on Brahman”, who asked whether all the wealth in the world could make her immortal — and, refusing her share of his property, received instead his teaching that all love is love of the Self.
Kapila
The legendary founder of Sāṃkhya, revered as the “first knower” (ādividvān) and, in later Hinduism, as an incarnation of Viṣṇu — a sage known almost entirely through myth, to whom India credits the first systematic philosophy of consciousness and nature.
Gautama Buddha
The prince who left his palace to seek an end to suffering, awoke under the Bodhi tree, and taught the Four Noble Truths, the Middle Way and no-self (anattā).
Mahāvīra
The twenty-fourth and last tīrthaṅkara of Jainism — a prince of the eastern Gaṅgā plain who renounced everything at thirty, practised twelve years of extreme austerity, attained omniscience, and taught a path of radical non-violence, truth and non-possession for thirty years.
Vālmīki
The ādikavi — “first poet” — to whom the Rāmāyaṇa is attributed; by legend a highway robber who became a sage, and whose grief at the death of a bird became the first verse.
Pāṇini
The grammarian of ancient Gandhāra whose Aṣṭādhyāyī — 4,000 rules generating the whole of Sanskrit — is the most rigorous description of any language before modern linguistics, and one of the great intellectual achievements of antiquity.
Kauṭilya (Cāṇakya)
The Brahmin strategist who, by tradition, made Candragupta Maurya emperor and wrote the Arthaśāstra — the ancient world’s most comprehensive treatise on statecraft, economics, law, diplomacy, espionage and war. India’s Machiavelli, two thousand years before Machiavelli.
Aśoka
The Mauryan emperor (r. c. 268–232 BCE) who, after the slaughter of his conquest of Kaliṅga, turned to Buddhism and governed by “dhamma” — non-violence, tolerance and welfare — proclaimed in edicts carved on rocks and pillars across India. His lion capital is India’s emblem; his wheel is on its flag.
Jaimini
The sage credited with the Mīmāṃsā Sūtras, the founding text of Vedic hermeneutics — and, in legend, a disciple of Vyāsa who heard the Mahābhārata from his master.
Kaṇāda
The founder of Vaiśeṣika and traditional author of the Vaiśeṣika Sūtras — the sage remembered as India’s first atomist, who taught that everything perceptible is built from eternal, indivisible particles.
Bādarāyaṇa
The author, by tradition, of the Brahma Sūtras — the systematisation of the Upaniṣads that became the root text of every school of Vedānta. Often identified with Vyāsa, compiler of the Vedas and author of the Mahābhārata.
Bharata Muni
The legendary sage credited with the Nāṭyaśāstra — the founding treatise of Indian theatre, dance, music and aesthetics, and the theory of rasa.
Aśvaghoṣa

Gautama Akṣapāda
The founder of the Nyāya school and traditional author of the Nyāya Sūtras — the first systematic Indian treatise on logic, knowledge and debate. Legend gave him eyes in his feet.
Nāgārjuna
Founder of the Madhyamaka (“Middle Way”) school of Buddhism, who argued that all things are empty (śūnya) of independent existence — including emptiness itself.
Patañjali
The compiler of the Yoga Sūtras — 196 terse aphorisms that define yoga as the stilling of the mind — honoured by tradition also as the grammarian of the Great Commentary on Pāṇini and as an incarnation of the serpent Ādiśeṣa.
Kundakunda
The most revered Digambara Jain teacher — author of the Samayasāra, which distinguishes the absolute standpoint, from which the soul is pure consciousness untouched by karma, from the conventional standpoint, from which it is bound.
Tiruvaḷḷuvar
The Tamil poet-sage who wrote the Tirukkuṟaḷ — 1,330 couplets on virtue, wealth and love that form the most revered ethical work in Tamil, translated into more languages than almost any other Indian text.

Kālidāsa
The greatest poet and dramatist of classical Sanskrit — author of Śakuntalā, The Cloud Messenger and the Birth of Kumāra — whose art of love, nature and longing made him “the Shakespeare of India”.
Bhartṛhari
The 5th-century philosopher of language who taught that ultimate reality is the Word (śabda-brahman), that meaning flashes forth as a whole (sphoṭa), and that all knowledge is shot through with language — and, by tradition, the poet of the Three Centuries on love, worldly wisdom and renunciation.
Dignāga
The founder of Buddhist logic and epistemology — only perception and inference give knowledge, perception grasps bare particulars, concepts are constructions, and words mean by excluding (apoha). He revolutionised the logic of every Indian school.
Gauḍapāda
The earliest systematic teacher of Advaita Vedānta, whose verses on the Māṇḍūkya Upaniṣad taught that nothing has ever really been born — the waking world is like a dream, and the one consciousness only seems to become many.
Dharmakīrti
The 7th-century Buddhist logician who perfected Dignāga’s epistemology — proving momentariness, refuting a creator God and the Veda’s authority, and defining knowledge by its reliability — the most formidable philosophical opponent the Hindu schools ever faced.
Kumārila Bhaṭṭa

Śāntideva

Āṇṭāḷ
The only woman among the twelve Tamil Āḻvār saints (9th century) — a girl who wore the garland meant for Viṣṇu, refused any human husband, and wrote the Tiruppāvai and Nācciyār Tirumoḻi, poems of longing for God as her bridegroom.
Abhinavagupta
The towering Kashmiri polymath (c. 950–1016) — the great systematiser of non-dual Kashmir Śaivism and the greatest theorist of Indian aesthetics, who taught that in the experience of art (rasa) the self tastes its own blissful consciousness.
Udayana
The great Nyāya philosopher of Mithilā who gave Indian philosophy its classic proofs of God’s existence, defended the reality of the self against the Buddhists, and closed the classical age of Nyāya-Vaiśeṣika.
Rāmānuja
Founder of Viśiṣṭādvaita — “qualified non-dualism” — who argued against Śaṅkara that the world and souls are real, forming the body of a personal God.
Hemacandra
The Jain polymath of 12th-century Gujarat — grammarian, poet, logician, lexicographer, historian and royal adviser — called “the omniscient of the Kali age”, who persuaded a king to ban animal slaughter.
Basavaṇṇa (Basava)
The 12th-century Kannada saint, poet and statesman who founded the Vīraśaiva (Liṅgāyat) movement — rejecting caste, temples, priests and the Vedas, preaching that work is worship and that every devotee carries Śiva on his body.
Jayadeva

Jñāneśvar
The 13th-century Marathi saint-poet who, at about twenty, wrote the Jñāneśvarī — a 9,000-verse commentary on the Bhagavad Gītā in Marathi that founded Marathi literature and the Vārkarī devotional tradition — and entered living samādhi at twenty-one.
Gaṅgeśa Upādhyāya
The 14th-century logician of Mithilā who founded Navya-Nyāya, the “New Logic”, in his Tattvacintāmaṇi — a technical language of such precision that it became the common idiom of Indian scholarship for five centuries.
Lal Ded (Lalleśvarī)
The 14th-century Kashmiri Śaiva mystic who wandered naked singing short verses (vākhs) of fierce, non-dual devotion — the mother of Kashmiri literature, claimed equally by Hindus and Muslims.
Rāmānanda
The 14th–15th century Vaiṣṇava teacher of Vārāṇasī who, by tradition, opened devotion to Rāma to all castes and both sexes, and whose disciples included Kabīr, Ravidās and Pīpā — the bridge between South Indian theology and North Indian bhakti.

The 15th–16th century Bengali saint who led an ecstatic movement of singing the names of Kṛṣṇa, regarded by his followers as Kṛṣṇa and Rādhā in one body — founder of Gauḍīya Vaiṣṇavism and ancestor of the Hare Kṛṣṇa movement.
Mīrābāī
The 16th-century Rajput princess who declared herself the bride of Kṛṣṇa, defied her royal in-laws, survived (the legends say) cups of poison and a basket with a snake, and left her palace to sing — the most beloved woman poet of North India.
Tulsīdās
The 16th-century poet of Vārāṇasī who retold the Rāmāyaṇa in Avadhī as the Rāmcaritmānas — the most widely read and recited book in North India — and wrote the Hanumān Chālīsā, sung daily by millions.

Swami Vivekananda
The Bengali monk, disciple of Ramakrishna, who brought Vedānta and Yoga to the West at the 1893 Parliament of Religions in Chicago (“Sisters and brothers of America!”), preached a “practical Vedānta” of service to humanity as service to God, and awakened modern Hindu self-confidence.
Mahatma Gandhi
The leader of India’s independence movement and the philosopher of satyāgraha — “truth-force”, non-violent resistance — who turned the Jain and Hindu ideal of ahiṃsā into a method of mass politics, and whose ideas of truth, non-violence, self-rule and simplicity changed the twentieth century.
