Chan, Sŏn and Thiền: Zen's Sister Traditions

By Tim Yu · Updated 2026-06-04

“Zen” is the Japanese name for a tradition that was born in China and spread across East Asia under four different names — but they are all the same word. Chan in China, Sŏn in Korea, Thiền in Vietnam and Zen in Japan all render the Sanskrit dhyana, “meditation.” They are one lineage wearing four cultural faces.

The short answer

The word most Westerners know is Zen, but Zen did not begin in Japan. As Encyclopaedia Britannica notes, the word “derives from the Sanskrit dhyana, meaning ‘meditation,’” which passed into Chinese as chan (from chan-na) and from there across the region. Britannica even lists the tradition under all its names at once — “Chan, Sŏn, Seon, Thien, Zen Buddhism.” So Chan (China) is the original; Sŏn (Korea), Thiền (Vietnam) and Zen (Japan) are its later branches. All four are forms of Mahayana Buddhism that share a single conviction: awakening is realised not chiefly through study or ritual but through direct meditative insight, passed from master to student. Chan, Sŏn, Thiền and Zen are best understood as one family — a point worth keeping in view as you read about Zen and the wider branches of Buddhism. (Unfamiliar terms are in the glossary.)

One word, four pronunciations

It helps to see the chain of translation laid out plainly:

• Dhyana — the original Sanskrit term for meditative absorption.
• Chan (禪) — the Chinese rendering, short for chan-na, the form in which the tradition first took shape.
• Sŏn (Seon) — the Korean pronunciation of the same character.
• Thiền — the Vietnamese pronunciation.
• Zen — the Japanese pronunciation, and the name by which the tradition became famous in the West.

Nothing in the meaning changes from one country to the next. What changes is the language, and with it the cultural soil — the art, the institutions, the favoured methods — in which the tradition grew. Treating “Zen” as a purely Japanese phenomenon, as popular writing in the West often does, quietly erases the Chinese, Korean and Vietnamese traditions that are every bit as old and deep. The honest picture is a single river with four named stretches.

Chan: the original, in China

Chan began in China, and its founding story centres on a single figure: the Indian monk Bodhidharma. Tradition holds that he travelled from India to China and there established the Chan school. Britannica places him “in the 5th century” as “the monk who supposedly introduced true Buddhism to China,” and honours him as the first patriarch of the lineage.

Here honesty requires a careful word. The accounts of Bodhidharma, Britannica cautions, “are largely legendary, and historical sources are practically nonexistent” — even the two brief early notices disagree on his age and nationality. So Bodhidharma is rightly called the tradition’s founding figure, the personification of its origins, rather than a man whose biography we can reconstruct in detail. The famous verse later attached to him captures the spirit of the whole tradition: “A special transmission outside the scriptures, not relying on words or letters; pointing directly to the human mind, seeing true nature is becoming a Buddha.” (We tell his story more fully in our life of Bodhidharma.)

Huineng and the Platform Sutra

If Bodhidharma is Chan’s legendary root, its great flowering came with Huineng (638–713), revered as the sixth patriarch. Britannica calls him “the sixth great patriarch of Zen (Ch’an in Chinese) Buddhism and founder of the Southern school, which became the dominant school of Zen, both in China and in Japan.” The teaching associated with him is preserved in the Platform Sutra, a text Britannica dates “most likely composed in the 8th century CE” and “attributed to the sixth patriarch Hui-neng” — though, the entry adds with scholarly care, it is “most likely the work of subsequent disciples who sought to legitimate their school by devising a lineage of dharma masters leading back to Bodhidharma.” The Platform Sutra’s emphasis on sudden awakening — the recognition, in a flash, of a “true nature” already present — became central to how Chan, and later all Zen, understood the path.

The “five houses”

As Chan matured in China it did not stay a single stream. It branched into what tradition calls the “five houses” — distinct lineages of teaching and style. Two of these proved especially enduring and exported themselves across the sea: the Linji school and the Caodong school. Their names will be familiar in their Japanese forms, because Britannica traces exactly this descent when it lists the later “Japanese Zen lineages: Ōbaku (Chinese: Huanbo), Rinzai (Chinese: Linji), and Sōtō (Chinese: Caodong).” In other words, what Japan would later know as Rinzai is the Chinese Linji, and what it would know as Sōtō is the Chinese Caodong. The roots are Chinese; the names most readers recognise are Japanese.

Sŏn: Chan in Korea

Chan crossed into Korea, where it is called Sŏn (often romanised Seon), and there it was carried and shaped by generations of monks. The decisive systematiser was Jinul (1158–1210), a monk of the Goryeo period who, distressed by the laxity he saw in the monastic life of his day, set out to renew Korean Buddhism and to reconcile meditation with scriptural study. He is remembered as the founder of the order that endures as the heart of Korean Sŏn to this day.

That order is the Jogye (Chogye). Britannica describes it as a Sŏn sect “derived from Ch’an, the Chinese form of Buddhism, known as Sŏn in Korea and as Zen in Japan,” which “became the mainstream of Korean Buddhism” and is “now one of the largest Buddhist sects in Korea.” Korean Sŏn became known for its rigorous, undivided commitment to meditation — and in particular for sustained inquiry into a single penetrating question or “critical phrase,” held until it cracks open the ordinary, discursive mind. It is the same Chan project of direct insight, given a distinctively Korean intensity and form.

Thiền: Chan in Vietnam

In Vietnam the tradition is called Thiền, and its arrival is traced to an Indian monk. Britannica records plainly that “the first dhyana (Zen; Vietnamese thien), or meditation, school was introduced by Vinitaruchi … an Indian monk who had gone to Vietnam from China in the 6th century.” Vinitaruci’s school was the first of several Chan lineages to reach Vietnam over the following centuries, each adding to a layered Vietnamese Thiền tradition that interwove with the country’s wider Mahayana and Pure Land devotion.

In the modern era, Thiền’s most influential voice on the world stage has been the Vietnamese teacher Thich Nhat Hanh, whose gentle, practical presentation of mindful awareness — born from this Vietnamese Thiền lineage — carried Zen practice to vast new audiences far beyond Asia. Through him, the Vietnamese branch of the family has arguably done as much as any to shape how meditation is understood in the contemporary West.

What the four share

Strip away the four names and the differences of country, and a common core stands out clearly. Across Chan, Sŏn, Thiền and Zen, three commitments recur:

• Meditation first. The tradition’s very name is the word for meditation. Seated meditation, and the steady cultivation of direct awareness, sit at the centre of practice — ahead of doctrinal study, ritual or speculation.
• Mind-to-mind transmission. Awakening is understood to pass directly from teacher to student, “outside the scriptures.” Britannica stresses the conviction “that awakening can be achieved by anyone but requires instruction in the proper forms of spiritual cultivation by a master.” The teacher–student lineage, not the text alone, is the carrier of the living tradition.
• Pointing to the mind. All four traditions share the aim summed up in the verse linked to Bodhidharma: “pointing directly to the human mind, seeing true nature is becoming a Buddha.” The goal is not to acquire a new belief but to wake up to what, in this view, is already the case.

These shared commitments are why it is fair — and more accurate — to speak of one tradition under four names rather than four separate religions that happen to resemble one another.

One lineage, four faces

Chan, Sŏn, Thiền and Zen are a single tradition that learned to speak four languages. It began in China with the legendary Bodhidharma, flowered under Huineng and the Platform Sutra, branched into the five houses, and then travelled outward — to Korea, where Jinul gave it the enduring form of the Jogye Sŏn order; to Vietnam, where it grew into Thiền and reached the modern world through Thich Nhat Hanh; and to Japan, where it became the Zen that the West came to know first.

To grasp this is to be cured of a common confusion. “Zen” is not Japanese in origin, and it is not the whole story; it is the most famous name for a meditation tradition that is also Chinese, Korean and Vietnamese, and Indian before that. Seeing all four together — one dhyana, four faces — is simply seeing the tradition whole.
