Schools of Buddhism
In the decades following the reign of Emperor Ashoka, the unified Buddhist community fractured into two distinct groups. The Sthavira Nikaya, meaning the Elders, and the Mahasamghika, or Great Community, emerged from a disagreement over monastic rules known as vinaya. Most scholars believe this initial split occurred after Ashoka's death in the third century BCE. Doctrinal differences soon followed geographical separation, creating a complex web of sects that would define Buddhism for centuries to come.
From these two main branches arose numerous sub-sects with unique philosophical stances. The Sarvastivada school flourished in northwest India and Kashmir, teaching that all dharmas exist across past, present, and future time. Their doctrine became known as an eternalist theory of time. Another group called the Pudgalavada introduced a controversial concept of the person, founded by the elder Vatsiputra around 280 BCE. These early divisions set the stage for the diverse traditions we see today.
Sri Lanka stands as the sole surviving home of Theravada Buddhism, the only extant mainstream non-Mahayana school. This tradition traces its lineage directly to the Vibhajyavadins who arrived on the island during Ashoka's reign circa 240 BCE. They established the Sri Lankan Mahavihara monastery, which preserved their conservative teachings against later innovations.
The Pali language serves as both the sacred tongue and lingua franca for this entire tradition. Monastics study the Tipitaka, also known as the Pali Canon, which remains the only complete Buddhist canon written in a classical Indian language. Different sects within Theravada emphasize varying aspects of these texts or commentaries like the Visuddhimagga. Modern movements such as the Vipassana meditation practice have revived interest in Indian Theravada, though the core tradition remains rooted in Southeast Asia and Sri Lanka.
Indian Mahayana Buddhism produced two major philosophical schools that shaped East Asian thought. Nagarjuna founded the Madhyamaka tradition, also called the Middle Way or Emptiness-view, around the second century CE. His followers developed distinct sub-schools including Svatantrika and Prasangika branches led by thinkers like Bhaviveka and Chandrakirti.
A separate movement emerged in the fourth century AD when Asanga and Vasubandhu established the Yogacara school. Known variously as Vijnanavada or Cittamatra, this tradition emphasized consciousness-only doctrines. These philosophical frameworks influenced countless East Asian sects including Tiantai, Huayan, and Zen. The compilers of Tathagatagarbha texts formed a third stream that heavily impacted devotional practices across Tibet and China.
During the Han dynasty, Buddhism entered China from Central Asia and began adapting to local cultural contexts. This process created uniquely Asian interpretations of Buddhist texts through figures like Zhiyi, Fazang, and Linji. Over half of the world's Buddhists now practice within these East Asian traditions spanning China, Japan, Korea, Vietnam, Taiwan, Malaysia, and Singapore.
Chinese monastics generally follow the Dharmaguptaka Vinaya code while integrating Confucian and Taoist elements into their practice. The Pure Land sect focuses on devotion to Amitabha Buddha, whereas Chan meditation emphasizes direct insight. Japanese schools like Shingon syncretized esoteric rituals with indigenous Shinto beliefs. Vietnamese Buddhism often blends Theravada, Confucianism, and folk religion into unified community practices without distinct sectarian boundaries.
Medieval India gave rise to Esoteric Buddhism among adepts known as Mahasiddhas who developed unique tantric features. These practitioners maintain separate texts called Buddhist Tantras alongside classic scriptures. Their methods include mantras, dharanis, mudras, mandalas, and visualizations of deities and Buddhas that distinguish this path from other forms.
Tibetan Buddhism represents the most widespread tradition within this category, practiced across Tibet, Mongolia, Bhutan, Sikkim, and parts of Russia. Monastics here follow the Mulasarvastivada Vinaya code while preserving lineages such as Nyingma, Kagyu, Gelug, and Sakya. The Rimé movement promotes non-sectarian approaches to these diverse teachings. Modern Western adaptations include groups founded by converts like Ngakpa Chogyam's Aro lineage established in the 1980s.
B. R. Ambedkar delivered a historic speech on the 14th of October 1956 at Deekshabhoomi in Nagpur during his conversion ceremony. This event launched the Navayana or Dalit Buddhist movement which reinterpreted Buddhism for social welfare rather than individual liberation alone. His work inspired countless new religious movements throughout the twentieth century including Humanistic Buddhism led by Taixu.
Contemporary developments range from Buddhist feminism to secular adaptations practiced in Europe and North America. Organizations like the Plum Village Tradition founded by Thich Nhat Hanh emphasize engaged Buddhism alongside meditation practice. Groups such as Soka Gakkai and Dharma Drum Mountain have grown into major international institutions. These modern branches reflect how ancient traditions continue evolving to meet changing global needs while maintaining core philosophical principles.
