What Thiền names
Thiền is the Vietnamese reading of the Chinese chán, itself the Chinese transliteration of the Sanskrit *dhyāna* — meditative absorption. As a tradition-name it indicates the lineage Bodhidharma is held to have brought from India to China in the early sixth century, transmitted through Huineng and his successors, and exported from China across East Asia in distinct national forms: Korean Seon, Japanese Zen, Vietnamese Thiền. The four schools share the same canonical history — the transmission of mind outside the scriptures attributed to Bodhidharma, the Platform Sūtra attributed to Huineng, the koan-and-sitting curricula that the Song-dynasty Chinese masters developed — but each took the inherited material in its own direction under its own historical pressures. The Vietnamese version is the least known to English-language readers; it is the version the Mahāyāna Buddhism of contemporary Vietnam has been built around for fourteen centuries, and the version through which one of the most widely-read late-twentieth-century Western-facing teachers — Thich Nhat Hanh — was himself trained.
How the tradition reached Vietnam
The first transmission of thiền to Vietnam is conventionally dated to 580 CE, when the Indian monk Vinītaruci (Vietnamese: Tỳ-ni-đa-lưu-chi) — said to have been a direct disciple of the third Chinese Chán patriarch Sengcan — settled at the Pháp Vân pagoda in what is now the Bắc Ninh province of northern Vietnam. The Vinītaruci lineage continued for about six centuries. A second major transmission arrived in 820 CE when the Chinese master Vô Ngôn Thông (Chinese: Wu Yantong) established the school that would carry his name. A third — the Thảo Đường school, founded by a Chinese monk who had been brought to Vietnam as a captive and was recognised in his captivity as a master — arrived in 1069. The most important indigenous Vietnamese school, Trúc Lâm (Bamboo Forest), was founded in 1299 by the abdicated emperor Trần Nhân Tông; it synthesised the earlier transmissions and is the principal stream the contemporary Vietnamese Buddhist clergy is descended from. The Lâm Tế (Vietnamese reading of Linji) and Tào Động (Vietnamese reading of Caodong, the Chinese ancestor of Sōtō) lineages arrived in subsequent centuries; the modern Vietnamese sangha holds all of these inheritances in parallel.
The Plum Village synthesis
The figure through whom most English-language readers meet thiền is Thich Nhat Hanh, the Lâm Tế–lineage Vietnamese monk who was ordained at sixteen at the Từ Hiếu pagoda in Huế in 1942, exiled from Vietnam for his peace activism in 1966, and who founded the Plum Village practice community in the Dordogne region of southern France in 1982. The Plum Village synthesis is recognisably thiền in its lineage but distinct in its register: the *mindfulness* vocabulary the community uses in English, the *interbeing* gloss on dependent origination, the walking meditation and bell-of-mindfulness practices that punctuate the daily schedule, and the integration of *engaged Buddhism* — the school's response to the Vietnam War years — are Nhat Hanh's own contributions, layered over the inherited Lâm Tế curriculum. The community has spread from the original Plum Village monastic centre to affiliated monasteries in the United States, Germany, Thailand and elsewhere; the thiền practice they transmit is the version most non-Vietnamese readers will have encountered.
Where to encounter it
Plum Village's English-language written corpus runs through Thich Nhat Hanh's *The Heart of the Buddha's Teaching* — the most systematic single-volume presentation of the doctrinal architecture the school works inside — and the more devotional and applied volumes *Peace Is Every Step*, *Being Peace* and *Living Buddha, Living Christ*. The book that introduced most English-language readers to the practice itself is *The Miracle of Mindfulness*, the 1975 short volume that re-presents the satipaṭṭhāna contemplations in a Vietnamese register accessible to the Western lay reader. The video corpus includes Nhat Hanh's talk on meditating on emptiness, signlessness and aimlessness, the dharma talk on what the Buddha actually taught, the talk on the Buddhist understanding of reality and the teaching on refreshing one's way of seeing things. The course-form companion is the Plum Village–authored *Body and Mind Are One*, and the Plum Village written voice in periodical form runs through Br. Trời Đức Niệm's reflection on peace within and a planet healed.
What it isn't
Thiền is not a watered-down or diluted form of Chinese Chán — the Vietnamese tradition has been continuous for fourteen centuries, is held by a sangha measured in the millions, and has produced indigenous masters (Trần Nhân Tông, Hương Hải, Liễu Quán) of the same calibre as its Chinese and Japanese counterparts. Thiền is also not a synonym for Plum Village; the contemporary Vietnamese Buddhist field includes a far broader range of monasteries and lineages, many of which are doctrinally and stylistically distinct from the Plum Village synthesis that has had such success in the English-language reception. And thiền is not simply Vietnamese Zen in the sense that zen is a generic East Asian style with a Vietnamese accent; the Vietnamese tradition holds a distinctive emphasis on the joint cultivation of thiền and tịnh — the thiền-tịnh song tu practice that combines Chán-style meditation with Pure Land recitation, standard in Vietnamese monasteries and almost unknown in Japanese Zen.
