Buddhism

• Buddhism is a religious and philosophical tradition founded in the 5th–4th century BCE in north-eastern India by Siddhartha Gautama, who after his awakening became known as the Buddha ("the Awakened One").
• It grew into one of the world's major religions and a defining force in Indian history, art, architecture, literature and political thought.
• Three words must be fixed at the outset. Dharma (Pali dhamma) here means the moral law and the body of the Buddha's teaching. Sangha is the monastic community of monks and nuns who carry that teaching forward. Nirvana (Pali nibbana) is liberation — the "blowing out" of craving and the end of the cycle of rebirth.
• Buddhism is best understood not as the worship of a god but as a practical path: the Buddha diagnosed suffering as the human problem and prescribed a disciplined ethical-mental path to end it.

1. Life of the Buddha — Chronology & Key Events

• The life of the Buddha is itself an exam topic, because each great event is tied to a sacred place.
• By the dating UPSC normally follows, Siddhartha Gautama was born about 563 BCE (the Mahayana tradition prefers c. 480 BCE) at Lumbini, in the foothills of present-day Nepal — a site later marked by an Ashokan pillar.
• His father Suddhodana was the chief of the Shakya clan (hence the Buddha's epithet Shakyamuni, "sage of the Shakyas"); his mother Mahamaya died soon after his birth, and he was raised by his stepmother Mahapajapati Gotami.
• He married Yashodhara and had a son, Rahula.
• According to tradition, the sheltered prince was shaken by the Four Sights (Chatur Nimitta) — an old man, a sick man, a corpse and a serene wandering ascetic — which revealed old age, disease and death, and pointed to renunciation as the way out.

• At the age of 29 he left the palace in the Great Renunciation (Mahabhinishkramana).
• He first studied meditation under the teachers Alara Kalama (a Samkhya-influenced master) and Uddaka Ramaputta, then practised six years of extreme asceticism with five companions — until he concluded that self-torture was as useless as self-indulgence, and adopted the Middle Path.
• At Bodh Gaya (then Uruvela, on the banks of the Niranjana/Phalgu river), seated under the Bodhi tree (a peepal, Ficus religiosa), and having resisted the temptations of Mara (the personification of desire and death), he attained enlightenment (Bodhi) at the age of 35.
• He then walked to the Deer Park at Sarnath (Isipatana/Mrigadava, near Varanasi) and delivered his First Sermon — the Dhammachakkappavattana Sutta, the "Turning of the Wheel of Dhamma" — to his five former companions (Kondanna and the others), expounding the Four Noble Truths and the Eightfold Path for the first time.

• For 45 years the Buddha taught across the Gangetic plain, winning royal patrons such as Bimbisara and Ajatashatru of Magadha and Pasenadi of Kosala, and wealthy lay donors such as the merchant Anathapindika, who gave the Jetavana monastery at Shravasti.
• He admitted women to the Sangha — his stepmother Mahapajapati Gotami became the first bhikkhuni (nun), a landmark in ancient gender history.
• He died (attained Mahaparinirvana) at the age of 80 at Kushinagar, in the sal grove of the Malla kings, after a last meal (the disputed sukara-maddava) offered by Cunda the smith; his last words were that "all conditioned things are impermanent — strive on with diligence." The Eight Sacred Sites (Ashtamahasthanas) commemorate his life: Lumbini (birth), Bodh Gaya (enlightenment), Sarnath (first sermon), Kushinagar (death), Shravasti (miracles), Rajgir (residence), Vaishali (announcement of his coming death) and Sankashya (descent from heaven).

2. Core Teachings — the Heart of the Dhamma

• The whole of early Buddhist doctrine radiates from the Four Noble Truths (Chatvari Arya Satyani), set out in the first sermon as a physician's diagnosis and cure.
• The first truth, Dukkha, is that ordinary existence is shot through with suffering and unsatisfactoriness — birth, ageing, sickness, death, and the failure to keep what we love.
• The second, Samudaya, identifies the cause: craving (tanha, "thirst") — for sensual pleasure, for continued existence, and even for non-existence.
• The third, Nirodha, is the good news that suffering can cease, because if craving is extinguished its product ends; that cessation is nirvana.
• The fourth, Magga, gives the practical road to that cessation — the Noble Eightfold Path.

• The Eightfold Path (Ariya Atthangika Magga) is not eight sequential steps but eight dimensions cultivated together, traditionally grouped under three heads.
• Under Prajna (wisdom) fall Right View and Right Intention.
• Under Sila (ethical conduct) fall Right Speech, Right Action and Right Livelihood.
• Under Samadhi (mental discipline) fall Right Effort, Right Mindfulness and Right Concentration.
• This path is itself the famous Middle Path (Majjhima Patipada) — a deliberate avoidance of the two extremes of harsh self-mortification (which the Buddha had tried and rejected) and indulgent pleasure-seeking.

• Three deeper doctrines underpin the path.
• The Three Marks of Existence (Tilakkhana) hold that everything conditioned is stamped with Anicca (impermanence), Dukkha (unsatisfactoriness) and Anatta (no permanent self). Anatta is the single sharpest break from Upanishadic thought: where the Upanishads affirm an eternal atman identical with Brahman, Buddhism denies any unchanging soul, seeing the person as a stream of ever-changing physical and mental processes. Dependent Origination (Pratityasamutpada) — "this being, that arises; this ceasing, that ceases" — explains existence as a twelve-linked chain (nidanas) running ignorance → mental formations → consciousness → name-and-form → the six sense-bases → contact → feeling → craving → clinging → becoming → birth → ageing-and-death; break any link (especially craving) and the chain of suffering unwinds.
• The law of karma and rebirth drives the cycle of samsara: intentional actions bear fruit and propel rebirth — yet, since there is no soul, it is a stream of conditioned consciousness, not a soul, that is reborn. Nirvana is the end of that stream of craving — not annihilation but the extinguishing of the "flame" of desire, attainable even in this life, with parinirvana the final release at the death of one who is liberated.

• For practical ethics, lay followers keep the Five Precepts (Panca Sila) — abstaining from killing, stealing, sexual misconduct, false speech and intoxicants — while novice monks observe Ten Precepts (the five plus rules against eating after noon, entertainments, garlands/perfumes, high beds and handling gold or silver).
• Refuge in the Three Jewels (Triratna) — Buddha, Dhamma, Sangha — is the formal act of becoming a Buddhist.

• Two points repay deeper thought, because examiners love the apparent paradox.
• First, how can there be rebirth without a soul? Buddhism resolves this by denying any permanent, unchanging self while affirming a continuity of process: what passes from one life to the next is not a soul but a conditioned stream of consciousness, each moment caused by the previous one, "like one flame lighting another" — the second flame is neither the same as the first nor entirely different.
• Karma is therefore not the act of a soul but the moral momentum carried by this stream; crucially, in contrast to Jainism, the Buddha defined karma as intention (cetana) — "it is intention, O monks, that I call karma" — so it is the will behind an act, not the physical act, that binds.
• Second, what exactly is nirvana? It is not a heaven and not annihilation; the very word means "blowing out", the extinguishing of the three fires of greed, hatred and delusion.
• One who attains it is freed from craving and therefore from rebirth; a person who reaches nirvana while still alive lives out the remainder of that life in serene freedom, and at death attains parinirvana, the final release from which there is no return.
• The Buddha consistently refused to speculate on metaphysical questions that did not lead to liberation — whether the world is eternal, whether the liberated being "exists" after death — treating them, in the parable of the poisoned arrow, as distractions from the urgent work of ending suffering.

3. The Sangha — the Monastic Community

• The Sangha is the community of bhikkhus (monks) and bhikkhunis (nuns) and is one of the Three Jewels.
• Monastic life is governed by the Vinaya Pitaka, whose code (the Patimokkha, with around 227 rules for monks) is recited at the fortnightly Uposatha assembly so that breaches may be confessed.
• Originally the monks were wandering mendicants who begged their food; over time they settled into permanent monasteries (viharas), especially during the three-month rainy-season retreat (vassa).
• The relationship between Sangha and laity is reciprocal — the laity give material support (dana) and the monks give teaching and merit.
• From simple dwellings such as Veluvana (Rajgir) and Jetavana (Shravasti) this institution eventually produced the great monastic universities of Nalanda, Vikramashila and Odantapuri.

4. The Buddhist Councils

• Four great councils (sangiti) shaped the canon and the divisions of Buddhism.
• The First Council (c. 483 BCE) met at the Saptaparni Cave, Rajgriha, immediately after the Buddha's death; convened by Mahakashyapa under the patronage of King Ajatashatru, it compiled the teachings orally — Ananda reciting the discourses (Sutta Pitaka) and Upali the monastic rules (Vinaya Pitaka).
• The Second Council (c. 383 BCE) at Vaishali, about a century later, quarrelled over ten relaxations of discipline sought by the Vajjiputtaka monks; it produced the first schism, splitting the order into the orthodox Theravada (Sthaviravada) and the liberal Mahasanghika.
• The Third Council (c. 250 BCE) at Pataliputra, under Emperor Ashoka and presided over by Moggaliputta Tissa, purged the Sangha of impostors, added the Abhidhamma Pitaka to complete the Tripitaka, and launched organised missions abroad — Ashoka's son Mahinda and daughter Sanghamitta carrying the Dhamma (and a Bodhi-tree sapling) to Sri Lanka.

• The Fourth Council exists in two separate traditions, and distinguishing them is a classic exam point.
• In the Theravada account it met around 29 BCE in Sri Lanka under King Vattagamani Abhaya, where the Tripitaka was written down for the first time on palm leaves.
• In the Mahayana account it met around 72 CE in Kashmir under the Kushana emperor Kanishka, presided over by Vasumitra (with Ashvaghosha), and compiled the great commentary Mahavibhasha; this council is associated with the consolidation of the Mahayana.

5. Major Schools / Sects

• Buddhism developed three great vehicles (yanas).
• The oldest surviving school, Theravada ("Way of the Elders" — often contrasted as Hinayana, the "Lesser Vehicle", a label its followers do not use of themselves), keeps the Pali canon, holds up the Arhat (one who wins personal liberation) as its ideal, and emphasises monastic discipline and meditation; it spread to Sri Lanka and South-East Asia (Myanmar, Thailand, Cambodia, Laos). Mahayana ("Greater Vehicle"), arising around the 1st century CE, recast the Buddha as a transcendent, almost divine being, multiplied Buddhas and Bodhisattvas, and made its ideal the Bodhisattva — a compassionate being who postpones his own nirvana to save all others (key Bodhisattvas: Avalokiteshvara of compassion, Manjushri of wisdom, Maitreya the future Buddha).
• It uses Sanskrit texts — the Prajnaparamita ("Perfection of Wisdom") sutras, the Lotus Sutra and the Diamond Sutra — and produced the two great philosophical systems of Nagarjuna's Madhyamaka (Sunyavada, the doctrine of emptiness) and Asanga and Vasubandhu's Yogachara (Vijnanavada, "mind-only"); it spread to China, Korea, Japan, Tibet and Vietnam. Vajrayana ("Diamond/Thunderbolt Vehicle", also Tantric Buddhism or Mantrayana), which developed from about the 6th–7th century CE and flourished under the Pala dynasty, adds mantras, mudras, mandalas, esoteric ritual and guru-initiation, holds up the Siddha (accomplished tantric master) as its ideal, gives prominence to female deities such as Tara, and spread to Tibet, Nepal, Bhutan and Mongolia (its Tibetan schools include Nyingma, Kagyu, Sakya and the Gelug of the Dalai Lama).
• Besides these, earlier "mainstream" schools such as the Sarvastivada ("everything — past, present and future — exists"), Sautrantika and Sammitiya were historically important.

• It is worth understanding why Mahayana ("the great vehicle") arose and what it changed, since this is the single biggest doctrinal development in Buddhist history.
• Where early Buddhism held up the Arhat, who wins his own liberation, Mahayana exalted the Bodhisattva, who out of karuna (compassion) vows to become a fully enlightened Buddha for the sake of all beings and postpones his own final nirvana until everyone is saved — an ideal open to laypeople as well as monks.
• The Bodhisattva trains through the six perfections (paramitas) — generosity, morality, patience, energy, meditation and wisdom (prajna).
• Mahayana also transformed the figure of the Buddha himself, teaching the three bodies (trikaya) — the earthly nirmanakaya, the heavenly sambhogakaya and the absolute dharmakaya — so that the historical Gautama became one manifestation of an eternal, cosmic Buddha-principle, surrounded by celestial Buddhas (such as Amitabha) and Bodhisattvas who could be worshipped and prayed to, giving Buddhism a devotional warmth it had lacked.
• Philosophically it produced two great systems: Nagarjuna's Madhyamaka, whose doctrine of shunyata (emptiness) holds that nothing has independent, intrinsic existence because everything arises dependently; and the Yogachara of Asanga and Vasubandhu, whose vijnanavada ("consciousness-only") traces the world back to mind.
• Vajrayana then built on this Mahayana base, claiming to offer a faster path to Buddhahood within a single lifetime through the disciplined use of mantra (sacred sound), mudra (ritual gesture), mandala (sacred diagram) and the guidance of a guru.

6. Buddhist Literature — the Tripitaka

• The canon is the Tripitaka ("three baskets"), preserved most completely in Pali.
• The Vinaya Pitaka (Basket of Discipline) holds the monastic rules (its parts being the Suttavibhanga, Khandhaka and Parivara).
• The Sutta Pitaka (Basket of Discourses) gathers the Buddha's teachings into five Nikayas — Digha, Majjhima, Samyutta, Anguttara and Khuddaka; the Khuddaka in turn contains the much-loved Dhammapada (verses of doctrine), the Jatakas (birth-stories) and the Therigatha (verses of the nuns).
• The Abhidhamma Pitaka (Basket of Higher Teaching), the latest of the three, is a systematic philosophical-psychological analysis in seven books.
• Beyond the canon, several texts are historically priceless: the Milindapanho ("Questions of King Milinda"), a dialogue between the Indo-Greek king Menander and the monk Nagasena; the Sri Lankan chronicles Dipavamsa and Mahavamsa; Ashvaghosha's Sanskrit biography Buddhacharita; the Mahayana biographies Lalitavistara and Mahavastu; and the Jatakas (547 stories), which are a treasury of social and economic history.

• A word on why this literature matters so much to the historian.
• Because the Buddhist texts were composed in Pali and the everyday vernaculars rather than in the Sanskrit of the Brahmanical elite, and because they describe the lives of merchants, artisans, farmers, courtesans and kings rather than only priests and rituals, they are among our richest windows onto the society and economy of the age of the second urbanisation (the rise of the Mahajanapadas, coinage and long-distance trade).
• The Jatakas, in particular, are crowded with caravans, guilds, ports and village life.
• The dialogue of the Milindapanho preserves a genuine philosophical encounter between Greek and Indian thought; the Sri Lankan chronicles the Dipavamsa and Mahavamsa supply the chronological backbone (including much of what we know of Ashoka) that the Indian sources lack; and the travel-records of the Chinese pilgrims Fa-Hien (Gupta period) and Xuanzang/Hiuen Tsang (Harsha's period), who came to collect and study these very texts, are first-rate eyewitness accounts of Indian society, religion and the great monastic universities.
• The Abhidhamma, finally, is one of the earliest sustained attempts anywhere to build a systematic psychology, analysing experience into fleeting mental and physical events (dhammas).

7. Buddhist Art & Architecture

• Buddhist art passed through two great phases.
• In the early aniconic phase (before about the 1st century CE) the Buddha was never shown in human form; his presence was indicated by symbols — the lotus for his birth, the Bodhi tree for enlightenment, the wheel (Dharmachakra) for the first sermon, the stupa for his death/parinirvana, the empty throne for his presence, footprints (Buddhapada), the bull (his birth-sign) and the horse (the renunciation).
• In the later iconic phase the Buddha image itself was carved, in three regional schools: Gandhara (Greco-Roman influence, grey schist, wavy hair and toga-like robes), Mathura (indigenous, red sandstone, shaven head, thin clinging robe) and Amaravati (white marble narrative reliefs), culminating in the serene, idealised Gupta Buddha.
• The architecture appears as great stupas (Sanchi, Bharhut, Amaravati, Nagarjunakonda, the Dhamek stupa at Sarnath), the rock-cut chaityas and viharas (Ajanta, Ellora's Buddhist caves 1–12, Karle, Bhaja, Kanheri), the horseshoe chaitya-arch (gavaksha), and the monastic universities (Nalanda, Vikramashila, Odantapuri, and Somapura in Bangladesh).

• The role of Ashoka (r. c. 268–232 BCE) deserves emphasis, because no single figure did more for the religion.
• After the carnage of the Kalinga war, Ashoka embraced the Buddha's teaching and turned the resources of an empire to its spread: he convened the Third Council, dispatched missions as far as Sri Lanka and the Hellenistic west, is traditionally said to have built 84,000 stupas to enshrine the Buddha's relics, undertook pilgrimage to the sacred sites (erecting commemorative pillars, as at Lumbini), and inscribed his ethic of Dhamma — non-violence, tolerance, respect for elders and all sects — on rocks and polished sandstone pillars across the subcontinent; the Lion Capital from his Sarnath pillar is independent India's state emblem, and its Dharmachakra sits at the centre of the national flag.
• The great monastic universities carried the tradition's intellectual prestige: Nalanda, founded under the Guptas (5th c. CE) and flourishing under Harsha and the Palas, was a vast residential university drawing students from across Asia (Xuanzang both studied and taught there), with a celebrated library complex; its destruction by Bakhtiyar Khilji around 1193 CE, together with the fall of Vikramashila and Odantapuri, was a decisive blow to Indian Buddhism.
• In our own time the network of these places has been revived as the Buddhist Circuit, a pillar of India's cultural diplomacy and "soft power" with the Buddhist nations of Asia.

8. Spread of Buddhism — India & the World

• Within India the decisive patron was Ashoka, whose policy of Dhamma, his dhamma-mahamattas (officers of morality), his rock and pillar edicts, his stupa-building and his pilgrimages spread the religion across the subcontinent.
• From there it travelled outward: to Sri Lanka through Mahinda and Sanghamitta (3rd c. BCE); along the Silk Road through Central Asia to China, Korea and Japan (the routes later travelled in reverse by the Chinese pilgrims Fa-Hien and Xuanzang/Hiuen Tsang); to South-East Asia in its Theravada form; and to Tibet, Nepal, Bhutan and Mongolia in its Vajrayana form (carried by Padmasambhava).
• Its great learning centres — Nalanda (founded c. 5th c. CE, where Xuanzang studied), Vikramashila and Odantapuri in Pala Bengal, Valabhi in Gujarat and the earlier Taxila — made India the intellectual heart of the Buddhist world.

9. Buddhism & Political Thought; Its Decline & Social Impact

• Buddhism shaped political ideals as well as religion. Ashoka's Dhamma — though not identical with Buddhism — drew on it to build a welfare ethic of tolerance and non-violence, and the Buddhist ideal of the chakravartin (the righteous "wheel-turning" universal monarch) offered kings a model of legitimate rule; later patrons included Kanishka (Kushana), Harsha and the Pala dynasty, the last great Buddhist royal house of India.
• Buddhism declined in India after about the 12th century for several converging reasons: the loss of royal and merchant patronage as trade routes shifted; the revival of a reformed, philosophically powerful Hinduism (notably Shankaracharya's Advaita, which absorbed Buddhist ideas) and the rise of Bhakti; the assimilation of the Buddha into the Hindu pantheon as an avatar of Vishnu; the increasing ritualisation and esotericism of late Vajrayana and the monks' growing isolation from the laity; and finally the destruction of the great monasteries by the Turkic invasions (Bakhtiyar Khilji sacked Nalanda c. 1193 CE).
• Yet its social impact was lasting: it challenged the varna/caste hierarchy by opening the Sangha to all; it promoted the use of Pali and other vernaculars over Sanskrit, democratising knowledge; it advanced ahimsa and helped end large-scale Vedic animal sacrifice; and it admitted women to the monastic order.
• In modern times B.R. Ambedkar revived it as an instrument of social justice, converting with some 600,000 followers at Nagpur on 14 October 1956 to a reformed "Navayana" Buddhism explicitly framed as a rejection of caste.

Revision tip: draw a single timeline — Birth → Renunciation → Enlightenment → First Sermon → Councils → Spread → Decline — and pin one fact to each node.

Buddhism is a GS-I (art, culture & ancient history) and GS-IV (ethics) favourite. The examiner rewards an analytical, multi-dimensional treatment — not biography — and a strong modern angle (Ambedkar, soft power).
