What is Buddhism?

Definition

Buddhism is a major world religion and philosophical tradition founded by Siddhartha Gautama (the Buddha) in the 5th century BCE in the northeastern Indian subcontinent. Unlike theistic religions, Buddhism does not center on a creator god; instead, it focuses on the nature of suffering, the path to its cessation, and the attainment of enlightenment (nirvana). The Buddha’s teachings, preserved in various canons (the Pali Canon for Theravada Buddhism, the Mahayana sutras for East Asian traditions, and the Tibetan Kangyur and Tengyur for Vajrayana), propose that all existence is characterized by suffering (dukkha), that suffering arises from craving and ignorance, and that the Noble Eightfold Path provides the method for liberation. Buddhism spread from India to Central Asia, Southeast Asia, China, Korea, Japan, and Tibet, adapting to local cultures and developing distinct traditions (Theravada, Mahayana, Vajrayana) while maintaining core teachings. With approximately 500 million followers, Buddhism is the fourth-largest religion globally, after Christianity, Islam, and Hinduism.

Why It Matters

Buddhism matters because it is one of the most influential systems of thought in human history, shaping the cultures, art, politics, and philosophies of Asia for over two millennia. Its emphasis on impermanence, non-attachment, and compassion has provided a counterweight to materialist values in both traditional and modern societies. In the West, Buddhism has profoundly influenced psychology (particularly through mindfulness-based stress reduction, developed by Jon Kabat-Zinn from Buddhist meditation practices), environmental ethics (Buddhist teachings on interdependence inform ecological movements), and secular philosophy (the “Buddhist Modernism” movement, which separates meditation from religious doctrine). Buddhism also matters as a living tradition: monastic communities in Thailand, Myanmar, Sri Lanka, Tibet, and Japan preserve ancient practices, while convert communities in Europe and the Americas adapt Buddhist principles to contemporary contexts. The tradition’s flexibility — its ability to accommodate local gods, rituals, and social structures while maintaining core teachings — has allowed it to survive the decline of Indian Buddhism (due to Muslim conquests and Hindu revivalism) and flourish in new cultural environments.

Example

Theravada Buddhism (“Doctrine of the Elders”): the oldest surviving Buddhist tradition, practiced primarily in Sri Lanka, Thailand, Myanmar, Cambodia, and Laos. It emphasizes monasticism, the Pali Canon as the authoritative scripture, and the goal of becoming an arhat (a fully enlightened being who will not be reborn). Theravada monasteries follow the Vinaya — a detailed code of monastic discipline that governs everything from robe-wearing to food acceptance. Mahayana Buddhism (“Great Vehicle”): the dominant form in China, Korea, Japan, and Vietnam, which expanded the Buddhist goal from individual liberation to the liberation of all beings. Mahayana introduces the bodhisattva ideal — an enlightened being who postpones nirvana to help others achieve enlightenment. Key Mahayana texts include the Heart Sutra, the Lotus Sutra, and the Diamond Sutra. Vajrayana Buddhism (“Diamond Vehicle” or “Thunderbolt Vehicle”): the tradition of Tibet, Mongolia, and Bhutan, which incorporates Tantric practices (visualization, mantra recitation, ritual) to accelerate enlightenment. The Dalai Lama, the spiritual leader of Tibetan Buddhism, is the most globally recognized Vajrayana figure.

Internet Angle

On the internet, Buddhism is a sprawling ecosystem of practice, study, and commerce. Meditation apps (Headspace, Calm, Insight Timer) repackage Buddhist techniques as secular wellness tools, generating hundreds of millions in revenue while sparking debates about cultural appropriation and the commodification of spiritual practice. Reddit hosts active Buddhist communities: r/Buddhism (general discussion), r/theravada, r/zen, and r/vajrayana offer spaces for practitioners to ask questions, share experiences, and debate doctrine. YouTube features Dharma talks from teachers like Thich Nhat Hanh (Vietnamese Zen master), Ajahn Brahm (Thai Forest Tradition), and Pema Chödrön (Shambhala Buddhism), often with millions of views. The internet has also facilitated Buddhist textual preservation: websites like SuttaCentral.org provide free access to the Pali Canon and other Buddhist texts in multiple languages; the 84000 project translates Tibetan Buddhist scriptures into English; and digital archives preserve manuscripts from traditions threatened by political persecution (particularly Tibetan Buddhism). Online Buddhist courses, virtual retreats, and Zoom-based meditation groups expanded dramatically during the COVID-19 pandemic, creating new models of Buddhist practice that exist entirely in digital space.
