This chapter surveys the extraordinary cultural developments in the subcontinent between about 600 BCE and 600 CE, a period that produced some of the world's most influential thinkers and most magnificent architecture. The central figures are the Buddha (Gautama Siddhartha, c. 566-486 BCE) and Mahavira, the last Tirthankara of Jainism (c. 540-468 BCE), whose teachings of renunciation, non-violence and spiritual effort challenged the ritual-dominated religion of the Brahmanas. Around the same time, the great Sanskrit epic Mahabharata and the philosophical school known as Samkhya developed, and the Brahmanical tradition itself was reworked into what became classical Hinduism.
The chapter also shifts the focus from texts alone to the material world of belief: the stupas, temples and sculptures that were built as physical expressions of faith. It shows how Buddhism, in particular, grew from a small monastic movement into a pan-Asian religion with grand monuments at Bharhut, Sanchi and Amravati, each stupa embodying the teachings of the Buddha in stone. In doing so, the chapter links the history of ideas with the history of buildings and of the patronage that paid for them.
The sixth century BCE was a time of rapid change. New states and cities were growing, the economy was expanding, and the old certainties of tribe, clan and sacrificial ritual were being questioned. The Buddhist and Jain traditions arose in this context of social ferment, offering new answers to the problem of human suffering. They addressed not only elite males but also merchants, kings and householders, promising liberation attainable through personal effort rather than through the expensive rituals of Brahmana priests.
At the same time, the Buddha's teachings were a response to the prevailing philosophical speculations of the age. The Samkhya school, for example, taught that the world is composed of two principles, the spiritual (purusha) and the material (prakriti), and that suffering arises from their confusion. The Buddha, however, rejected metaphysical debates as useless distractions and instead focused entirely on the practical problem of suffering and its cessation. This emphasis on experience and practice is what made Buddhism attractive and accessible.
The Buddha taught that the world is full of suffering (dukkha) and that suffering arises from desire or craving (tanha). This insight is summarised in the Four Noble Truths: life is suffering; suffering arises from craving; suffering can be ended; and the way to end it is the Eightfold Path. The Eightfold Path prescribes right views, right resolve, right speech, right conduct, right livelihood, right effort, right mindfulness and right concentration, a middle path avoiding the extremes of self-indulgence and self-mortification.
The Buddha's teachings were preserved and transmitted orally for centuries, in the language of the people, Pali. Only in the first century BCE were they written down, by monks in Sri Lanka. The oral tradition is the reason Pali Buddhist texts contain constant repetitions and formulae, an aid to memorisation. Historians stress that the Buddha never claimed divine status: he described himself as a teacher who had found the way, not as a god or a saviour. His first sermon was delivered at Sarnath, near Varanasi, to his five former companions.
Vardhamana, known as Mahavira, was a Kshatriya prince who renounced the world at about thirty years of age and spent twelve years in intense meditation and fasting before attaining enlightenment at about 42. He was the last (24th) Tirthankara of the Jains. The central Jain doctrine is ahimsa, absolute non-violence towards all living beings, carried to an extreme that led monks and nuns to sweep the ground before them and wear cloth over the mouth to avoid harming insects.
Jainism also taught the doctrine of the soul (jiva) and non-soul (ajiva), and the three jewels of right faith, right knowledge and right conduct as the path to liberation. Mahavira is said to have had both a large following of monks and nuns and lay followers. The first Jaina council was held at Pataliputra in the third century BCE, where the teachings were assembled. Jainism remained strong particularly in Gujarat and Rajasthan and among merchants, whose occupations of trade allowed them to practise non-violence more easily than farmers, who necessarily kill creatures in ploughing.
After the Buddha's death (parinibbana) at Kushinagar in 486 BCE, his teachings and relics were distributed among the followers, and stupas were raised over the relics. Buddhism spread rapidly, and by the time of Asoka it had become a major religion with royal patronage. Asoka, who styled himself a Buddhist, erected stupas and pillars and encouraged the monks. The stupa at Sanchi was originally built during Asoka's reign and enlarged in the first century BCE.
The sangha, the community of monks and nuns, was organised in monasteries (viharas) that were often located near trade routes, and merchants and guilds donated generously to them. The growth of the sangha meant that Buddhism became an institutionalised religion with rules of conduct laid out in the Vinaya Pitaka. The three baskets of the Buddhist canon, the Tipitaka, consist of the Sutta Pitaka (teachings of the Buddha), the Vinaya Pitaka (monastic rules) and the Abhidhamma Pitaka (philosophical analyses).
The stupa was originally a simple mound or heap, a semispherical structure containing relics of the Buddha or of monks. Over time it acquired a complex symbolism. The four sides of the gateways (toranas) of Sanchi are oriented towards the four cardinal directions. The entrance to the main path was built in such a way that it was approached at a tangent, so that one had to circumambulate (walk around) the stupa to enter. This pradakshina path, the act of walking around the sacred structure, became central to worship.
The stone railings (vedika) of Bharhut and Sanchi are covered with exquisite sculpture. These sculptures served both as decoration and as teaching aids, illustrating stories from the Buddha's life and the Jatakas. In early art, the Buddha was shown symbolically, through footprints, the bodhi tree or the wheel, and only from around the first century CE, at sites like Mathura and Gandhara, did the Buddha appear in human form. The chapter treats the stupa as a "building of faith" whose very architecture, from the layout of the toranas to the position of the relic chamber, expressed Buddhist belief.
The Sanchi stupa is built of brick and stone over the relics of the Buddha. Its essential elements are the dome (anda), the harmika (a small platform on top that symbolises the abode of the gods), the yashti (the mast) and the chhatri or umbrella on top. The whole structure sits on a raised terrace, and the entire edifice is surrounded by a stone railing with four elaborate carved gateways (toranas) at the cardinal points.
The umbrella at the top symbolises the Buddha, and the harmika and yashti together are said to symbolise the sacred Mount Meru, the centre of the universe. The circumambulation path allows the devotee to walk around the dome. The reliefs on the toranas depict the Jataka stories, scenes from the Buddha's life, and a rich array of human and animal figures. One of the most famous images shows the Great Departure, when the young prince Siddhartha left his father's palace on his horse Kanthaka, with attendants holding an umbrella over him.
A crucial discovery at Sanchi is the set of inscriptions on the stupa's ground balustrade that record donations by a wide range of people, including kings, queens, monks, merchants and, remarkably, many women and even some poor labourers who contributed the value of a day's wages. These inscriptions prove that the stupa was not a royal project alone but a community monument funded by many ordinary and extraordinary donors.
For example, some inscriptions mention donations by the guild of ivory workers, while others record gifts by women named in connection with their families. This pattern of lay patronage, in which donations to Buddhist institutions earned merit (punya), explains how Buddhism spread so effectively through the merchant classes. The chapter stresses that buildings like Sanchi must be understood not just as architecture but as the product of social relations, patronage and collective belief.
Buddhism was not the only religion to build. From the fifth century CE, temples dedicated to Hindu deities began to be constructed, and the form of the earliest temple can be traced to the simple shrine of the fourth century. The Puranas, composed around this time, laid out rules for making and installing images of deities, and prescribed appropriate rituals. The worship of deities through images (puja) with offerings of flowers, food and lamps became widespread, differing from the older Vedic fire sacrifices.
This new emphasis on personal devotion (bhakti) to a chosen deity was a departure from the world of the Vedas. The deity was now approached through the temple, where a priest could act as intermediary. The temple also became a focus of community life and a repository of wealth. The chapter notes that the Puranic religion, with its temples, images and festivals, provided the foundation of the Hinduism that survives today, a world of multiple gods and manifold practices.
The chapter ends by discussing the nature of the textual sources. The Buddhist and Jain texts are collections of sermons, rules and stories compiled over centuries; they were not written by the Buddha or Mahavira themselves. The Puranas were composed over a long period and contain genealogies, myths and ritual prescriptions. Each type of text has its own conventions, and historians must read them critically, distinguishing later additions from earlier material.
At the same time, the material evidence, the stupas, the railings, the sculptures and the inscriptions, offers a check on the texts. The donative inscriptions at Sanchi, for instance, tell us who actually funded the monuments, information the texts often do not provide. By reading texts and buildings together, the historian reconstructs a cultural world in which ideas were not just preached but built, funded, and experienced by people of every rank.

Between the Buddha's first sermon at Sarnath and the rise of the great stupas and temples, the subcontinent underwent a profound cultural transformation. New ideas of renunciation and liberation challenged the old world of ritual, and these ideas were given permanent physical form in stone. The stupa at Sanchi, funded by kings and by ordinary donors, and the early temples of the Puranic age, are both monuments to belief and witnesses to the societies that created them. The chapter teaches the student that religious history cannot be written from texts alone: it must also be excavated, read from inscriptions, and walked around in the pradakshina path of a stupa.
