Introduction
Buddhism is one of the most significant heterodox religious–philosophical traditions that emerged in ancient India during the 6th century BCE, a period marked by profound social, economic, and intellectual transformation. Founded by Gautama Buddha, Buddhism developed not merely as a religious faith but as a moral, ethical, and philosophical system that offered an alternative worldview to prevailing Brahmanical orthodoxy.
Unlike ritual-centric Vedic religion, Buddhism emphasized ethical conduct, mental discipline, and wisdom as means to overcome human suffering. Over time, it evolved into a powerful social force that challenged caste hierarchy, encouraged rational inquiry, and promoted compassion and non-violence. Its influence extended beyond India, shaping civilizations across Asia and later the modern world, making Buddhism a major chapter in both Indian and global history.
Socio-Religious Background
The rise of Buddhism cannot be understood without reference to the Later Vedic socio-religious environment.
Vedic Orthodoxy and Ritualism
By the 6th century BCE, Brahmanical religion had become increasingly ritualistic and rigid. Complex sacrifices (yajnas), dominance of Brahman priests, and emphasis on birth-based varna restricted spiritual access for large sections of society.
Varna System and Social Tensions
The rigidification of the varna hierarchy led to social dissatisfaction among Kshatriyas, Vaishyas, and lower groups. Urbanization and the rise of merchant classes further weakened the relevance of sacrificial rituals.
Rise of Shramana Movements
In response, several Shramana traditions—including Buddhism, Jainism, Ajivikas—emerged, advocating renunciation, asceticism, ethical living, and individual salvation.

Life and Role of Gautama Buddha (Brief Overview)
Gautama Buddha was born as Siddhartha Gautama at Lumbini (present-day Nepal) to a Kshatriya family of the Shakya clan. Sheltered in luxury, his worldview changed after encountering the Four Sights—old age, sickness, death, and asceticism—which revealed the universality of suffering.
Renouncing worldly life, he undertook severe penance before realizing the futility of extreme asceticism. He attained enlightenment at Bodh Gaya, discovering the Middle Path. His first sermon at Sarnath, known as the Dhammachakra Pravartana, laid the foundation of Buddhist doctrine.
Buddha functioned not as a prophet but as a teacher and guide, emphasizing rational understanding and self-effort.

Core Doctrines of Buddhism
Four Noble Truths
The Four Noble Truths form the philosophical backbone of Buddhism:
- Dukkha – Life is marked by suffering and dissatisfaction
- Samudaya – Desire (tanha) is the root cause of suffering
- Nirodha – Cessation of suffering is possible
- Magga – The Eightfold Path leads to liberation
These truths diagnose the human condition and prescribe a practical path for liberation.
Eightfold Path
The Eightfold Path represents the Middle Way and is divided into three components:
- Prajna (Wisdom): Right view, Right intention
- Shila (Ethical Conduct): Right speech, action, livelihood
- Samadhi (Mental Discipline): Right effort, mindfulness, concentration

Philosophical Foundations
Buddhist philosophy rests on key metaphysical and ethical principles:
Triratna
Buddhists take refuge in:
- Buddha – the enlightened teacher
- Dhamma – the doctrine
- Sangha – the monastic community
Anicca, Dukkha, Anatta
- Anicca: Impermanence of all phenomena
- Dukkha: Inherent unsatisfactoriness of existence
- Anatta: Rejection of a permanent soul
Nirvana
Nirvana represents the cessation of desire and liberation from the cycle of rebirth (samsara). Unlike moksha, it is conceived as a psychological and ethical state, not union with a supreme being.

Buddhist Sangha and Institutional Structure
The Sangha was the backbone of Buddhism’s organization and expansion.
Monastic Discipline
The Vinaya Pitaka regulated monastic life, prescribing ethical conduct, discipline, and communal decision-making.
Role of Monks and Nuns
Both Bhikkhus and Bhikkhunis were admitted, reflecting Buddhism’s relatively progressive outlook.
Democratic Functioning
Decisions were taken collectively, emphasizing equality and moral authority rather than birth.

Buddhist Literature
Buddhist teachings were compiled into the Tripitaka (Three Baskets):
- Vinaya Pitaka – Monastic rules
- Sutta Pitaka – Discourses of Buddha
- Abhidhamma Pitaka – Philosophical analysis
The use of Pali language made teachings accessible to the masses, unlike Sanskrit-dominated Brahmanical texts.
