Theravada, “the Doctrine of the Elders”, is the form of Buddhism practised across Sri Lanka and mainland Southeast Asia and, as Access to Insight puts it, “the sole survivor of those early non-Mahayana schools” that formed in India after the Buddha’s death. It preserves the early teaching in the Pali Canon, which “scholars generally agree contains the earliest surviving record of the Buddha’s teachings”, and it holds up the arahant, one who reaches nibbana by their own effort, as its ideal.

The short answer: what is Theravada Buddhism?

Theravada joins two Pali words, thera, an elder or senior monk, and vāda, speech or doctrine: “the doctrine of the Theras”, in the Pali Text Society’s dictionary. Its scriptures are the Pali Canon; its heartlands are Sri Lanka, Myanmar, Thailand, Cambodia and Laos; and its ideal is the arahant, the “perfected saint” who, in Britannica’s words, “attains enlightenment as a result of his own efforts”. Because it historically dominated southern Asia it is sometimes called “Southern” Buddhism, in contrast to the “Northern” Mahayana of China, Tibet, Japan and Korea. It is one of the great branches of Buddhism, and its Pali suttas supply most of the discourses quoted on this site, from the Four Noble Truths to the three marks of existence.

The name and the claim

Theravadins trace their lineage to the Elders (Sanskrit Sthavira), heirs to the senior monks of the first Buddhist sangha. Theravada, Britannica notes, “like all other Buddhist schools, claims to adhere most closely to the original doctrines and practices taught by the Buddha”, and Britannica’s main Buddhism entry places it in the “more conservative” of the two groups into which Buddhism developed after the Buddha’s death.

A word on terminology. Theravada is sometimes labelled Hinayana (“the lesser vehicle”), a disparaging term from Mahayana texts, and scholars differ even on whom it named: the Stanford Encyclopedia of Philosophy and Britannica’s main Buddhism entry treat it as the Mahayana name for the early non-Mahayana schools, Theravada among them, while Jonathan Silk, in Britannica’s Mahayana entry, says it “has no real-world referent and is never equivalent to non-Mahayana Buddhism, much less to any specific sect such as the Theravada”. The respectful and accurate name for this tradition is simply Theravada.

From India to Sri Lanka and across Asia

As the teaching spread across India after the Buddha’s death, differing interpretations divided the Sangha into as many as eighteen schools; apart from Theravada, all the non-Mahayana ones have died out. In the third century BCE, in the reign of the emperor Ashoka, Theravada reached Sri Lanka. The island’s chronicles credit Ashoka’s son, the monk Mahinda, who by the traditional reckoning arrived in 250 BCE; his sister Saṅghamittā, a nun, followed so that Sri Lankan women could be ordained. On the island the canon was handed down orally and then, probably during the first century BCE, first written down in Pali.

The tradition then spread eastward, becoming dominant in Myanmar in the late eleventh century and in Cambodia and Laos by the thirteenth and fourteenth, and Sri Lanka in turn drew on these lands: when ordination lapsed on the island, monks from Burma restored it after 1070, and monks from Siam in the eighteenth century. Mahayana, too, reached Myanmar and Sri Lanka at one time, but did not survive there.

The Pali Canon: scripture of the elders

Theravada’s scripture is the Pali canon, the Tipiṭaka or “three baskets”. Britannica says it “is thought to be the oldest complete canon within Buddhism”; the Mahayana schools revere it too, but add scriptures that Theravada does not accept as canonical. The three baskets are:

• The Vinaya Piṭaka, the basket of discipline: the rules and customs of the monastic Sangha.
• The Sutta Piṭaka, the basket of discourses: the sermons and utterances of the Buddha and his close disciples.
• The Abhidhamma Piṭaka, the basket of higher doctrine: a detailed analysis of mind and experience in seven books, from the Dhammasaṅgaṇi to the Paṭṭhāna (see Abhidharma).

The commentaries and the Visuddhimagga

Sri Lankan monks wrote commentaries on the canon in Sinhala, and from the fifth century CE these were collated and rendered into Pali. The central figure is Buddhaghosa, an Indian monk who came to Sri Lanka in the reign of King Mahānāma (410–432). According to the chronicles, the monks of the Mahāvihāra at Anurādhapura tested him with a thesis, and he answered with the Visuddhimagga, “The Path of Purification”, which holds much of the Theravāda Abhidhamma system; he went on to compile Pali commentaries on the Vinaya, the discourses and the Abhidhamma. The Sinhala commentaries he drew on were lost after the tenth century.

Pali, the language of text and chant

Pali had no alphabet of its own: the Tipiṭaka was first written in an early form of Brahmi script, and since then in Devanagari, Thai, Burmese, Roman and other scripts. Pali also remains the language of ritual. The protective paritta discourses of Sri Lanka’s Pirit Potha, the “Book of Protection”, among them the Ratana Sutta, are recited in temples and homes (see Buddhist chanting).

What Theravada Buddhists believe

Theravada teaching is framed by the Four Noble Truths of the first sermon: there is dukkha, suffering or unsatisfactoriness; craving causes it; it ceases when craving is relinquished; and the Noble Eightfold Path leads to that cessation. Not seeing these truths keeps beings in samsara, the round of birth, ageing, illness, death and rebirth, driven onward by craving in accordance with kamma, action that bears fruit according to its skilfulness.

The path is trained through virtue, concentration and discernment, and in meditation the practitioner learns to see all experience in terms of the three characteristics (tilakkhaṇa): anicca (inconstancy), dukkha and anattā (not-self). That seeing unfolds in four stages of awakening: stream-entry, once-returning, non-returning and arahantship, each marked by shedding or weakening “fetters” that bind a person to birth and death. The Abhidhamma gives these teachings their most systematic form, analysing what we take to be substantial persons and objects into complex, ever-changing processes.

The goal: the arahant

For Theravada the fully realised human being is the arahant: one who has walked the Eightfold Path to its end, uprooted the three poisons of greed, hatred and delusion, realised nibbana, and so will not be reborn into the round of samsara (see what is an arahant?). The canon states that completion in a set formula. In the discourse on the not-self characteristic (SN 22.59), delivered at Varanasi to the same five monks who had heard the first sermon, the disciple who has grown disenchanted with the five aggregates is fully released, and knows it:

Britannica’s phrase “as a result of his own efforts” captures the characteristic emphasis: liberation is won through one’s own practice of ethics, meditation and wisdom, with the Buddha as teacher and example. It is the point on which Theravada is most often contrasted with the Mahayana ideal of the bodhisattva, a contrast best drawn without ranking.

The bodhisatta in Theravada

Theravada does not reject the bodhisattva. As in early Indian Buddhism, it uses the word, in Pali bodhisatta, primarily for the Buddha in his former lives. The Jātaka tales record those lives, and the Buddhavaṃsa, a late addition to the Sutta Piṭaka, tells how, incalculable aeons ago, the ascetic Sumedha made his aspiration to buddhahood at the feet of the Buddha Dīpaṅkara and received a prediction of success. The ten perfections (pāramī) he then reflected on became the standard practice of the bodhisatta. Theravada also awaits the coming buddha Metteyya (Maitreya), the only bodhisattva the tradition generally honours. So the path to buddhahood is acknowledged, but, as Bhikkhu Bodhi explains, the school’s exponents mostly held it “reserved only for the very rare and exceptional individual”, though in time, he adds, the ideal won wider appeal, and the commentator Dhammapāla wrote a treatise on the perfections for those who took it up. Prince Mongkut of Siam, for one, formally took a bodhisattva vow and dedicated the merit of his efforts to future buddhahood.

Monks, nuns and the monastic orders

Theravada’s monks (bhikkhus) live by the Vinaya, whose core code, the Pāṭimokkha, has 227 rules for bhikkhus and 311 for bhikkhunīs. On the full-moon and new-moon uposatha days the monks of a monastery, if four or more, meet to hear one of them recite the 227 rules by heart. In Thai forest monasteries, for example, the rules include total celibacy, eating only between dawn and noon, and not handling money. Lay people feed the monks, on the morning almsround or at the monastery. There are no lifetime vows, though in some countries disrobing carries a stigma. Throughout Southeast Asia it is very common for young men to ordain as monks or novices for a short period, traditionally the three months of the rains retreat; in Thailand only a small proportion of monks stay in robes for life (see how to become a monk).

Monks belong to orders or fraternities, nikāyas, and Sri Lanka’s go back to three foundings. The Siyam Nikāya descends from the higher ordination brought from Siam in the eighteenth century, when not one fully ordained monk was left on the island; it ordained only men of the caste regarded as highest, so in 1799 a novice from outside that caste went to Amarapura in Burma for ordination and on his return founded the Amarapura Nikāya, in 1803. The Rāmañña Nikāya followed in 1863. H. R. Perera, writing in 1966, noted no doctrinal differences between the three, and in 2019 the Amarapura and Rāmañña chapters merged into a single body. A 2018 study of Buddhism and politics in Thailand gives 290,015 monks there at the end of 2014, not counting novices, and describes the Sangha as, until recently, mainly divided between the Mahanikai and the royally founded Thammayut (Dhammayut, “in accordance with the Dhamma”), which grew from the reform movement Mongkut led while a monk (see Buddhism in Thailand).

Nuns and the bhikkhunī revival

The order of nuns (bhikkhunīs) appears to have disappeared in Sri Lanka around the eleventh century, in a period of political turmoil that decimated the whole monastic community; only the monks’ order was restored from Burma. Without full ordination, women have lived as renunciant nuns: Burmese thila shins, Thai mae chis and, since the early twentieth century, Sri Lankan dasasil mātās, who take ten precepts. Theravada women began to take full ordination again in the United States in 1988, at Sarnath in 1996 and, above all, at Bodh Gayā in 1998, with the help of Chinese bhikkhunīs; since then the order has gained momentum in Sri Lanka and holds ordinations there. Its validity is contested, an objection repeatedly raised being that the Chinese nuns who officiated were Mahayana followers. See bhikkhunī ordination.

How Theravada is practised

For lay people, practice begins with the five precepts: refraining from killing, stealing, sexual misconduct, lying and intoxicants, which are at the core even of the monks’ 227 rules. Giving (dāna), not least alms food and cloth for robes, sustains the monks; in the Pali discourses giving, ethical conduct and meditation are the three grounds for making merit (AN 8.36).

The lunar calendar shapes the year, from the Vesak full moon to the uposatha days (the full moon, new moon and two quarter moons), when devout lay people may keep the eight precepts; in Thailand, Bhikkhu Khantipalo records, they usually give almsfood early in the morning and spend the day and night at the monastery. Monks keep the three-month rains retreat in one place, and in the month after it comes Kathina, when lay people offer cloth for a robe that the monks must finish before the next dawn. Daily chanting pays homage to the Buddha, Dhamma and Sangha: acts of respect and recollection, as our guide to whether Buddhists pray explains, rather than petitions to a god.

Meditation: calm and insight

Theravada cultivates calm (samatha) and insight (vipassanā), a pairing the canon itself names:

Tranquillity is developed until “passion is abandoned”; insight until “ignorance is abandoned”. Theravada’s own texts differ on how the two fit together: the suttas, as Access to Insight reads them, present them as qualities developed in tandem, while the Abhidhamma and the commentaries treat them as two distinct meditation paths. The Visuddhimagga favours building the meditative absorptions (jhānas) first, with forty possible objects of concentration, though it also mentions a “dry” insight that largely forgoes them (see Buddhist meditation and samatha vs vipassana).

The modern meditation movements

Insight meditation as a mass practice began in early twentieth-century Burma. The scholar of religion Erik Braun traces it to the monk Ledi Sayadaw (1846–1923), who spread Abhidhamma study among lay people, organised them to study and practise, and around 1904 presented “dry insight” as the sensible choice for a mass audience; until then, Braun writes, “few monastics meditated, and almost no laypeople”. Ledi’s pupil Saya Thetgyi taught the civil servant U Ba Khin, who trained S. N. Goenka for fourteen years before Goenka began teaching in India in 1969, and teachers such as Mahasi Sayadaw carried the practice beyond Burma.

In north-east Thailand the Thai Forest tradition grew from a return to forest living, discipline and meditation, associated above all with Ajahn Sao and his pupil Ajahn Mun (born in the 1870s). By the lineage’s own account, almost all the revered Thai meditation masters of the twentieth century were Ajahn Mun’s disciples or influenced by him, among them Ajahn Chah.

Theravada today

Theravada remains the main form of Buddhism in Sri Lanka, Myanmar, Thailand, Cambodia and Laos. Numbers are uncertain: Pew Research Center notes that most censuses and surveys do not record which branch Buddhists belong to, though it describes Theravada as the second-largest branch, after Mahayana. Access to Insight’s estimate, from 2004 data, was “well over 100 million” worldwide. Smaller communities live beyond the heartlands: in north-east India, where the Tai-Khamtis of Arunachal Pradesh and Assam, the Chakmas and others practise Theravada (Buddhism in India), and on China’s south-west border, where the Dai-lue of Sipsongpannā are Theravada Buddhists in a country where Mahayana is the norm.

In recent decades Theravada has put down roots in the West, with dozens of monasteries across Europe and North America and many lay meditation centres (Buddhism in the West). Ajahn Chah founded Wat Pah Nanachat in Thailand in 1975 to train foreign monks; in 1976 the English Sangha Trust invited his American-born disciple Ajahn Sumedho to London, where he set up the lineage’s first monastery outside Thailand. Amaravati followed in 1984, and Abhayagiri in California became the first American monastery of Ajahn Chah’s followers. In 1976, too, Joseph Goldstein, Sharon Salzberg and Jack Kornfield, who had studied under teachers of the Burmese insight lineage, opened the Insight Meditation Society in Barre, Massachusetts. Jon Kabat-Zinn, founder of the Mindfulness-Based Stress Reduction programme, recalls that its vision came to him one afternoon at IMS: one of the threads that tie today’s secular mindfulness to Theravada practice.

Theravada among the traditions

Beside Theravada stand the Mahayana (“Great Vehicle”) of East Asia and the Vajrayana of Tibet and the Himalayas. The differences are real: Theravada follows the Pali Canon where the Mahayana adds a vast further literature; it holds up the arahant where the Mahayana holds up the bodhisattva; and it reveres the historical Buddha rather than the many buddhas and bodhisattvas of the Mahayana. Jonathan Silk, in Britannica, calls the differences between Mahayana and non-Mahayana Buddhism “usually more a matter of degree and emphasis than of basic opposition”. Beneath them lies a shared trunk: the same Buddha, the same Four Noble Truths and Eightfold Path, the same goal of freedom from suffering. We set the two side by side in Theravāda vs Mahāyāna and contrast Theravada with Zen in Theravada vs Zen.
