South Asia (909 BCE – 819 CE): Iron Kingdoms, Oceanic Routes, and the Weave of Faiths

Regional Overview

Between the Hindu Kush and the southern capes of India stretched one of humanity’s most intricate civilizational tapestries.
From the Iron Age kingdoms of the Ganges plain to the maritime entrepôts of the Deccan and Sri Lanka, South Asia in the first millennium BCE – early CE was a world of transformation:
villages became towns, tribes became kingdoms, and merchants and monks carried ideas and goods from the Mediterranean to the South China Sea.
Two spheres balanced each other — the Upper South Asian interior, rooted in riverine agriculture and imperial administration, and the Maritime South Asian littoral, animated by monsoon commerce and cosmopolitan exchange.
Together they created a continental-oceanic civilization that fused agrarian power with maritime reach.

Geography and Environment

The northern heartland spanned the Indus–Ganga–Brahmaputra basins, shielded by the Himalayas and drained by some of the most fertile alluvium on Earth.
To the south rose the Deccan plateau and the coastal plains of Tamil Nadu, Kerala, and Andhra, encircled by the Indian Ocean and threaded with river deltas.
Across the seas lay Sri Lanka, Lakshadweep, and the Maldives, forming stepping-stones toward Arabia and Southeast Asia.

Monsoon regimes shaped every aspect of life:
the southwest rains (June–September) watered rice fields and replenished tanks, while the retreating monsoon powered voyages west and east.
Periods of drought were met with irrigation ingenuity — canals, tanks, and stepwells that transformed the landscape into a man-made hydrology.

Societies and Political Developments

Upper South Asia: From Mahajanapadas to Empires

By the mid-first millennium BCE, iron plows and surplus agriculture supported the Mahajanapadas, the “Great States” of northern India — Magadha, Kosala, Kuru-Panchala, and others.
Out of this matrix emerged the Mauryan Empire (4th–3rd c. BCE), the subcontinent’s first large-scale polity, uniting much of India and Afghanistan under Chandragupta Maurya and later Aśoka.
Aśoka’s edicts, carved in stone across the empire, broadcast moral and administrative order and announced Buddhism as an imperial ethos.

After the Mauryas, regional powers filled the landscape: Indo-Greek and Śaka (Scythian) dynasts in the northwest; Kushan rulers linking Gandhara to Central Asia; and the Gupta Empire (4th–6th c. CE) in the Ganga heartland, whose classical Sanskrit culture defined art, science, and kingship for centuries.
The Hūṇas shattered Gupta unity, but the Pāla dynasty (8th–9th c.) revived Buddhist scholarship in Bengal and Bihar, sustaining the great universities of Nālandā and Vikramaśīla.
In the Himalayas, Licchavi Nepal and early Bhutanese polities bridged India and Tibet, while northern Arakan (Myanmar) connected the Ganga world to Southeast Asia.

Maritime South Asia: Deccan and Peninsular Polities

South of the Vindhyas, the Satavahanas (2nd c. BCE – 3rd c. CE) controlled the Deccan’s trade arteries, issuing coins in Prakrit and sponsoring Buddhist stupas along caravan routes.
Their successors — Ikshvakus, Vakatakas, Kadambas, Pallavas, Chalukyas, and the enduring Chera–Chola–Pandya triad of Tamilakam — built a patchwork of kingdoms linked by commerce and culture.
On the island of Sri Lanka, the Anurādhapura monarchy (from the 4th c. BCE onward) expanded vast irrigation tanks and monasteries, anchoring the Theravāda Buddhist tradition.

By the early centuries CE, these southern polities were exporting pepper, pearls, gems, and fine textiles through ports like Muziris, Arikamedu, and Kaveripattinam.
Greek, Roman, and later Chinese merchants arrived with coins and amphorae, while Indian sailors mastered the seasonal monsoon routes to the Red Sea and the Straits of Malacca.

Economy and Exchange

Agriculture formed the continental core — rice in the east, wheat and barley in the northwest, millet and pulses in the Deccan — sustained by iron tools and canal irrigation.
Trade networks extended in every direction:

• Overland, through the Hindu Kush passes toward Persia and Central Asia;

• Seaward, through the Arabian Sea and Bay of Bengal to Africa, Arabia, and Southeast Asia.

Guilds (śreṇis) organized artisans and merchants; coins of silver, copper, and gold testified to a monetized economy.
Ports and caravanserais mirrored one another: harbors supplied pepper and pearls, while upland markets provided cotton and metals.
By integrating inland agrarian surplus with oceanic distribution, South Asia became the keystone between the Mediterranean and East Asia.

Technology and Material Culture

Advances in iron smelting, textile weaving, and architecture marked the age.
Stone and brick temples evolved from wooden prototypes; cave sanctuaries (Ajanta, Ellora) married engineering to faith.
In Sri Lanka, the hydraulic engineering of reservoirs and canals was among the most sophisticated in the ancient world.
Shipbuilding along both coasts produced plank-built vessels capable of open-ocean navigation, while astronomical knowledge guided monsoon sailing.

Art and literature flourished: Sanskrit epics and dramas, Prakrit poetry, Tamil Sangam anthologies, and Buddhist art from Gandhara to Amaravati conveyed a shared aesthetic of order and devotion.

Belief and Symbolism

Religious and philosophical plurality defined the region.
Vedic ritual evolved into Hindu devotional (bhakti) movements; Buddhism spread from the Ganga valley to Central Asia and Sri Lanka; Jainism flourished in western India.
Royal patronage crossed boundaries — Buddhist kings built Hindu shrines, Hindu dynasts endowed monasteries — reflecting a civilizational ethos of inclusivity and dialogue.
Symbolic architecture expressed cosmic geometry: the stupa as world-mountain, the temple as microcosm of the universe.

Adaptation and Resilience

Monsoon dependence fostered ingenuity: reservoirs, tanks, and flood-embankments turned uncertainty into reliability.
Polities survived invasion and drought by devolving power to local guilds and temples, creating layered sovereignty that could bend without breaking.
Maritime redundancy — alternate ports, seasonal scheduling — kept trade alive despite war or storm.
Cultural resilience came through translation and synthesis: foreign influences were absorbed, not imposed.

Regional Synthesis and Long-Term Significance

By 819 CE, South Asia had achieved an enduring civilizational equilibrium.
Its Upper sphere—from Gandhara and the Ganga to Bengal—embodied imperial administration, monastic learning, and continental coherence.
Its Maritime sphere—from the Deccan to Tamilakam and Anurādhapura—commanded the sea lanes, transmitting ideas and goods between worlds.
Each depended on the other: river basins fed the ports, and ocean trade enriched the plains.

This duality—continental and maritime—remains the natural division of South Asia, as visible in its geography as in its history.
Together they sustained a unified yet plural world, where faith, art, and commerce moved with the monsoon and where the ideals of Dharma, compassion, and cosmic order became the shared grammar of an entire region.

Upper South Asia (909 BCE – 819 CE): Early Iron and Antiquity — Mahājanapadas to Guptas, Kushans & Pālas, Himalayan Polities

Geographic & Environmental Context

Upper South Asia includes Afghanistan, Pakistan, North India, Nepal, Bhutan, Bangladesh, and north-western Myanmar (northern Arakan/Rakhine and the Chindwin valley).
Anchors: the Hindu Kush–Kabul–Gandhāra gateways (Kabul, Swat, Peshawar); the Indus–Punjab rivers (Ravi, Beas, Chenab, Jhelum, Sutlej); the Thar–Ghaggar margins; the Ganga–Yamuna Doab and Middle Ganga plain; Kashmir, the Siwalik/Terai belts, the Brahmaputra–Meghna delta (Sundarbans) and Chittagong Hills, plus the Chindwin–northern Arakan corridor.

Climate & Environmental Shifts

• First-millennium oscillations: alternating dry spells in the northwest and humid stability in the east.

• Rice agriculture anchored the Ganga–Brahmaputra lowlands; wheat, barley, and pulses shaped the Punjab.

• Steppe aridity cycles across Afghanistan and Central Asia influenced migration and trade along the Khyber–Bolan passes.

Societies & Political Developments

• Mahājanapada Age (~600–300 BCE): Sixteen city-states and republics competed until the Mauryan Empire(4th–3rd c. BCE) unified the Doab under Chandragupta Maurya; Aśoka’s inscriptions spread dhamma ideals from Gandhāra to Orissa.

• Indo-Greek, Śaka, and Kushan Kingdoms (1st–3rd c. CE): controlled Gandhāra–Punjab trade; Gandhāran Buddhist art fused Hellenistic and Indian forms.

• Gupta Empire (4th–6th c. CE): a classical florescence—Sanskrit literature, stone temple architecture, and iron-plough agronomy flourished.

• Hūṇa Invasions (5th–6th c.) fractured Gupta unity; regional dynasties (Aulikara, Maitraka, Vākāṭaka) rose.

• Pāla Dynasty (8th–9th c.) in Bengal–Bihar revived imperial reach under Dharmapāla; Buddhist universities at Nālandā and Vikramaśīla drew scholars from across Asia.

• Kathmandu Valley (Licchavi rule, c. 4th–8th c.) urbanized Himalayan trade; Bhutan remained a constellation of monastic–clan polities.

• Northwestern Myanmar (Arakan & Chindwin): small Buddhist chiefdoms linked Bengal and Upper Myanmar through river exchange.

Economy & Trade

• Agrarian base: iron ploughs and irrigation expanded rice cultivation; sugar pressing, textile weaving, and metalcrafts diversified surplus.

• Trade corridors: the Khyber–Bolan gateways, Ganga riverine traffic, and Bengal delta ports connected the subcontinent to Iran, Arabia, and Southeast Asia.

• Exports: cotton cloth, pepper, ivory, and beads; Imports: horses, gold, and silver.

• Monastic and temple pilgrimages stimulated internal commerce and urban growth.

Technology & Material Culture

• Iron metallurgy and advanced smithing; water-management works in the eastern plains.

• Temple and stūpa architecture in stone and brick; Gandhāran stucco and sculpture blending Indian and Mediterranean motifs.

• Coinages from punch-marked silver to Kushan copper-gold and Gupta gold dinars signaled monetized exchange.

Belief & Symbolism

• Buddhism, Jainism, and Hindu traditions coexisted; Aśokan pillars and Gupta temples embodied ethical and cosmic order.

• Pāla patrons sponsored the great mahāvihāras; the bhakti current stirred popular devotion.

• Ritual landscapes—from the Ganga ghats to Himalayan caves—encoded pilgrimage and power.

Adaptation & Resilience

• Eastern rice surpluses offset western drought losses.

• Multiple trade routes and caravan–river redundancy ensured recovery after wars.

• Himalayan buffer states mediated trans-range exchange and provided refuge for monks and merchants.

• Caste, guild, and monastic institutions stabilized production and learning through political flux.

Transition

By 819 CE, Upper South Asia stood as a multi-core civilization:

• the Pālas governing the east,

• post-Gupta successor states in the north,

• Kushan legacies in the northwest,

• and Licchavi Kathmandu anchoring the Himalayan hinge.
  Its synthesis of agrarian expansion, intellectual vitality, and trans-Asian connectivity laid the foundations for the medieval resurgence of pilgrimage kingdoms and temple economies that would follow.

Upper South Asia (909–478 BCE): Iron Landscapes, River Kingdoms, and the Foundations of Classical India

Political Geography

Between 909 and 478 BCE, Upper South Asia evolved from a landscape of regional Iron Age chiefdoms into an increasingly interconnected world of expanding kingdoms concentrated along the Indus, Ganga, and their tributaries. The Kuru and Panchala realms organized much of the western Gangetic plain, while Magadha emerged steadily in the middle Ganga basin as the strongest eastern power. Gandhāra occupied the crucial crossroads between the Iranian Plateau and the Indian plains, linking the subcontinent to Central Asia through the Khyber and Bolan corridors.

Rather than imperial unification, the defining political pattern of the age was the gradual concentration of authority around fertile river systems whose agricultural productivity supported larger settlements, fortified capitals, and increasingly specialized institutions.

Environmental Transformation

Iron tools accelerated the clearing of forests across the upper Gangetic basin and eastern plains. Rice cultivation expanded rapidly through the humid Ganga valley while wheat, barley, and pulses continued to dominate the Punjab and Indus systems. Irrigation remained relatively local, but river embankments, ponds, and seasonal water management steadily intensified agricultural reliability.

The contrast between regions became increasingly pronounced:

• the northwestern frontier remained shaped by steppe interactions and mountain gateways,
• the Punjab by mixed cereal agriculture,
• the central Doab by expanding cultivation,
• the eastern Ganga basin by increasingly intensive rice production,
• the Himalayan foothills by exchange between mountain and plain,
• and Bengal by riverine wetlands whose productivity supported growing populations.

These environmental systems—not dynastic boundaries—became the enduring framework of civilization.

Economy and Exchange

Agricultural surpluses supported expanding craft production, textile weaving, ironworking, ceramics, and long-distance trade. Painted Grey Ware communities gave way to increasingly urban economies, while Northern Black Polished Ware began appearing near the close of the period as evidence of rising commercial sophistication.

Taxila emerged as an important western entrepôt linking Iranian, Central Asian, and Indian exchange networks. River transport along the Ganga and Indus became progressively more important than overland movement within the plains, while Himalayan passes carried salt, timber, metals, livestock, and prestige goods between mountain communities and lowland kingdoms.

Rather than isolated cities, the landscape became a connected network of productive river valleys tied together through caravan routes and navigable waterways.

Society and Institutions

Increasing agricultural surplus supported stronger political institutions alongside the growing authority of hereditary elites, Brahmanical ritual specialists, and organized craft communities. The varna system became more formally articulated within later Vedic traditions, although local societies remained diverse across the subcontinent.

Permanent settlements expanded, fortified centers multiplied, and administrative organization gradually became more sophisticated without yet producing large territorial empires.

Intellectual and Religious Change

Later Vedic traditions matured throughout the western and central Gangetic plains, while philosophical debate increasingly questioned older sacrificial traditions. During the sixth century BCE, both Buddhism and Jainism emerged from this environment of intellectual experimentation, particularly within the eastern kingdoms centered on Magadha.

Simultaneously, Persian expansion incorporated Gandhāra and neighboring northwestern regions into the Achaemenid Empire, introducing new administrative methods, standardized coinage, and wider connections across western Asia while leaving local religious traditions largely intact.

The period therefore witnessed not the replacement of one belief system by another, but the coexistence of multiple religious traditions within an increasingly interconnected intellectual landscape.

Legacy of the Age

By 478 BCE, Upper South Asia had become a mature Iron Age civilization organized around expanding agricultural landscapes, integrated river transport, growing urban networks, and increasingly durable institutions. The environmental transformation of the Ganga basin, the rise of Magadha, the emergence of Buddhism and Jainism, and the integration of Gandhāra into wider Eurasian exchange established the foundations upon which the Mauryan Empire and the classical civilizations of South Asia would soon be built.

Upper South Asia (765–622 BCE): Regional Dynamics and Cultural Flourishing

Political Consolidation and Rivalries

Between 765 and 622 BCE, Upper South Asia witnessed further political consolidation and intense regional rivalries. Kingdoms such as the Kuru and Panchala in Haryana and western Uttar Pradesh experienced heightened competition and territorial disputes. Simultaneously, the Magadha kingdom in modern-day Bihar continued its steady rise, gradually becoming a formidable political force.

Socio-Religious Evolution

This age saw the further refinement of the caste system and the deepening complexity of Vedic rituals. Societal norms solidified around the Brahmins, Kshatriyas, Vaishyas, and Shudras, clearly defined within Vedic texts. Ritual sacrifices and ceremonies became increasingly elaborate, emphasizing the role of the priestly class.

Archaeological and Cultural Expressions

The Painted Grey Ware (PGW) culture remained prominent, its settlements and artifacts closely aligned with the historical accounts of the period. Additionally, the Northern Black Polished Ware (NBPW) began to appear, marking technological advancement and indicating evolving trade practices and urban sophistication in regions like Punjab, Haryana, and the central Gangetic plains.

Economic Integration and Expansion

Regional economies thrived, underpinned by advanced agricultural practices, extensive trade routes, and artisanal specialization. Key urban centers such as Taxila, now in Punjab, Pakistan, expanded significantly, facilitating extensive regional and interregional trade. Networks reaching Central and West Asia continued to foster economic prosperity and cultural exchanges.

Himalayan Regions and Interactions

The Himalayan territories, encompassing modern-day Himachal Pradesh, Uttarakhand, Nepal, Bhutan, Ladakh, and the region of present-day Sikkim, experienced increased interactions with the lowland kingdoms. While some peripheral areas of present-day Tibet had cultural exchanges with these Himalayan regions, the Tibetan plateau itself is part of the Upper East Asia subregion. Himalayan passes served as crucial conduits for trade, cultural exchanges, and the dissemination of religious beliefs.

Eastern and Northeastern Cultural Identities

In the northeastern territories, comprising present-day Assam, Arunachal Pradesh, Nagaland, Manipur, Meghalaya, Tripura, Mizoram, and adjacent parts of Bangladesh and northwestern Myanmar, regional cultures flourished. These societies maintained distinct pottery traditions, ritual practices, and economic connections with the wider Gangetic plains.

Religious and Artistic Maturation

Religious thought continued to evolve during this period, laying the foundations for future Hindu and Buddhist traditions. Artistic representations became increasingly sophisticated, reflecting religious iconography and elaborate rituals integral to the evolving spiritual landscape.

Legacy of the Age

The period between 765 and 622 BCE significantly shaped Upper South Asia's historical trajectory, strengthening regional kingdoms, enriching socio-religious practices, and enhancing economic prosperity. The cultural, religious, and political dynamics established during this time continued to resonate profoundly, influencing subsequent historical developments across the subcontinent.

Upper South Asia (621–478 BCE): Empires, Faiths, and Cultural Transformations

Rise of the Magadhan Empire

From 621 to 478 BCE, the region of Upper South Asia witnessed the rise of the powerful Magadhan Empire in the Gangetic plain, particularly in present-day Bihar. The Magadhan state, with its capitals initially at Rajgir and later at Pataliputra (modern-day Patna), gradually dominated surrounding territories through both diplomacy and military conquest. It eventually outpaced its neighbors, including the older kingdoms of Kuru and Panchala in Haryana and western Uttar Pradesh.

Emergence of Influential States

Concurrently, the age saw the prominence of influential states such as Avanti in western Madhya Pradesh, Kosala in eastern Uttar Pradesh, and Gandhara in the region corresponding to modern-day northern Pakistan and eastern Afghanistan. These states engaged in frequent conflicts and shifting alliances, shaping the region’s geopolitical landscape.

Persian Influence and the Achaemenid Empire

In this period, territories such as Gandhara, Balochistan, and significant parts of present-day Afghanistan were incorporated into the Achaemenid Persian Empire under rulers such as Cyrus the Great and Darius I. Persian rule brought significant administrative reforms, improved trade networks, standardized coinage, and introduced Zoroastrian religious ideas, leaving enduring influences in these western regions.

Religious Innovations: Buddhism, Jainism, and Zoroastrianism

This era was remarkable for the birth and rapid spread of major religious movements, notably Buddhism and Jainism. Siddhartha Gautama (the Buddha) and Mahavira (the founder of Jainism) actively preached across Northern South Asia, gaining substantial followings. Buddhism particularly found significant early patronage in Magadha.

Zoroastrianism, emerging from Persia, also impacted areas under Persian influence, particularly Gandhara and Balochistan, introducing new religious concepts and rituals that intermingled with local traditions.

Socio-Cultural and Caste Consolidation

The caste system became further entrenched, shaped increasingly by the Brahminical norms codified in the later Vedic texts. The division between the four major varnas—Brahmins, Kshatriyas, Vaishyas, and Shudras—solidified further, influencing all aspects of social and religious life.

Archaeological Developments and Urbanism

Material culture saw the flourishing of the Northern Black Polished Ware (NBPW), widely associated with urban centers and elite culture, indicative of growing economic prosperity. The influential city of Taxila in present-day Punjab, Pakistan, emerged as a prominent educational and trade hub, reflecting a vibrant cultural and economic exchange extending to Central and West Asia.

Himalayan and Northeastern Interactions

The Himalayan territories—including modern-day Himachal Pradesh, Uttarakhand, Nepal, Bhutan, Ladakh, and present-day Sikkim—continued robust interactions with lowland kingdoms, facilitating the movement of goods, religious ideas, and cultural practices. Simultaneously, the northeastern regions of Assam, Arunachal Pradesh, Nagaland, Manipur, Meghalaya, Tripura, Mizoram, and adjacent areas of Bangladesh and northwestern Myanmar developed distinctive regional identities and engaged in cultural exchanges with the Gangetic heartlands.

Cultural and Artistic Flourishing

The period witnessed remarkable artistic and architectural advancements. Influenced by religious developments, early Buddhist stupas and Jain temples began to dot the landscape, accompanied by sophisticated sculptures and artworks embodying religious and cultural ideals.

Peoples and Ethnic Dynamics

Ethnic groups such as the Pashtuns and Tajiks emerged distinctly in historical records during this period, especially within territories influenced by Persian culture and administration, adding further complexity and diversity to the region's demographic composition.

Legacy of the Age

The era from 621 to 478 BCE proved transformative for Upper South Asia, setting foundations for future imperial, religious, and cultural trajectories. The political dominance of Magadha, the advent of Buddhism and Jainism, and Persian administrative influences indelibly shaped the historical, social, and religious landscapes of the region.

The victory of good over evil is epitomized in the epic Ramayana (The Travels of Rama, or Ram in the preferred mod-ern form), while another epic, Mahabharata (Great Battle of the Descendants of Bharata), spells out the concept of dharma and duty.

More than twenty-five hundred years later, Mohandas Karamchand (Mahatma) Gandhi, the father of modern India, will use these concepts in the fight for independence.

The Mahabharata records the feud between Aryan cousins that culminated in an epic battle in which both gods and mortals from many lands allegedly fought to the death, and the Ramayana recounts the kidnapping of Sita, Rama's wife, by Ravana, a demonic king of Lanka (Sri Lanka), her rescue by her husband (aided by his animal allies), and Rama's coronation, leading to a period of prosperity and justice.

In the early twenty-first century, these epics remain dear to the hearts of Hindus and are commonly read and enacted in many settings.

In the 1980s and 1990s, Ram's story will be exploited by Hindu militants and politicians to gain power, and the much disputed Ramjanmabhumi, the birth site of Ram, will become an extremely sensitive communal issue, potentially pitting Hindu majority against Muslim minority.

The rudimentary administrative system headed by tribal chieftains is transformed by a number of regional republics or hereditary monarchies that devise ways to appropriate revenue and to conscript labor for expanding the areas of settlement and agriculture farther east and south, beyond the Narmada River.

These emergent states collect revenue through officials, maintain armies, and build new cities and highways.

By 600 BCE, sixteen such territorial powers—including the Magadha, Kosala, Kuru, and Gandhara—stretch across the North India plains from modern-day Afghanistan to Bangladesh.

The right of a king to his throne, no matter how it is gained, is usually legitimized through elaborate sacrifice rituals and genealogies concocted by priests who ascribe to the king divine or superhuman origins.

The Magadha culture has emerged in northern India, but there is little certain information available on the early rulers of Magadha.

The most important sources are the Puranas, the Buddhist Chronicles of Sri Lanka, and other Jain and Buddhist texts, such as the Pāli Canon.

Based on these sources, it appears that Magadha was ruled by the Haryanka dynasty for some two hundred years, from about 684 BCE to about 424 BCE.

Siddhartha Gautama himself was born a prince of Kapilavastu in Kosala around the fifth century BCE, during the Haryanka dynasty.

As the scene of many incidents in his life, including his enlightenment, Magadha is often considered a blessed land.

Siddhartha's father, seeking to prevent the child from becoming Buddha and instead raise a great monarch, allows the prince to experience only pleasure.

Siddhartha marries at age sixteen.

Siddhartha Guatama, on his way to political leadership at twenty-nine, takes a chariot trip outside the palace and, for the first time, witnesses irremediable suffering.

Overwhelmed with sorrow, he begins to contemplate renunciation of worldly pleasures, and leaves the palace, and his newborn son, to live as a religious ascetic and recluse.

During the next six years of ascetic self-mortification, Siddhartha travels from teacher to teacher, seeking but failing to find enlightenment.

He then recalls his meditation as a young boy, abandons his asceticism, and conceives of a "middle path" between asceticism and luxuries, determining to sit in meditation until attaining enlightenment.

He begins to meditate one evening while sitting under a pipal tree and, at dawn, is Supreme Buddha.

Concerned that his new insights are too deep for ordinary human beings, Siddhartha prepares to enter nirvana, but the god Brahma persuades him to delay his entry into nirvana and share his insight.

Theravada Buddhist doctrine places Siddhartha in a series with several earlier Buddhas and one Buddha—Mettayya, or Maitreya—yet to come, perceiving Buddhahood as lasting only the duration of life itself. Mahayana Buddhist doctrine claims Siddhartha as one historical manifestation of an eternal, ultimate Buddha, whose manifestations are called bodhisattva.

According to the Mahayana view, the historical Buddha—and other bodhisattvas—partake of a transcendental state of being; Siddhartha, in refusing to enter nirvana until all are saved, adopted the bodhisattva ethic.

In Chan (Ch'an), or Zen Buddhist doctrine, which denies the distinction between nirvana and samsara, or ordinary life, all beings equally partake of this Buddha-nature and are as much Buddha as Siddhartha himself.

As the Buddha, Guatama preaches his first sermon at Sarnath (a part of modern Varanasi, or Benares), on the north bank of the Ganges River, where he sets forth his doctrine of the Four Noble Truths, accepts lay disciples (male and female), and converts his former ascetic companions as the first monks.
