Buddhist Practices
Since Đổi Mới (1986) many reforms have allowed Buddhism to be practiced. Followers in Vietnam practice differing traditions without any problem or sense of contradiction. Few Vietnamese Buddhists would identify themselves as a particular kind of Buddhism, as a Christian might identify him or herself by a denomination, for example. Although Vietnamese Buddhism does not have a strong centralized structure, the practice is similar throughout the country at almost any temple.
Gaining merit is the most common and essential practice in Vietnamese Buddhism with a belief that liberation takes place with the help of Buddhas and bodhisattvas. Buddhist monks commonly chant sutras, recite Buddhas’ names (Amitabha most notably, doing repentance and praying for rebirth in the Pure Land).
The Lotus Sutra and Amitabha Sutra are the most commonly used sutras. Most sutras and texts have come from China and have been translated into Sino-Vietnamese (Han –Viet) rather than the vernacular making them largely incomprehensible to most practitioners.
Three services are practiced regularly at dawn, noon, and dusk. They include sutras (mainly devotional), reciting dharanis and Buddha’s name, and circumambulation (walking meditation). Laypeople at times join the services at the temple and some devout Buddhist practice the services at home. Special services such as Sam Nguyen / Sam Hoi (confession / repentance) takes place on the full moon and new moon each month. Chanting the name of Buddha is one way of repenting and purifying bad karma.
The overall doctrinal position of Vietnamese Buddhism is the inclusive system of Tiantai, with the higher metaphysics informed by the Huayan tradition; however, the orientation of Vietnamese Buddhism is syncretic without making such distinctions. Therefore, modern practice of Vietnamese Buddhism can be very eclectic, including elements from Zen, Pure Land, Tiantai, and popular practices from Esoteric Buddhism.
According to Charles Prebish, many English language sources contain misconceptions regarding the variety of doctrines and practices in traditional Vietnamese Buddhism.
We will not consider here the misconceptions presented in most English-language materials regarding the distinctness of these schools, and the strong inclination for "syncretism" found in Chinese and Vietnamese Buddhism. Much has been said about the incompatibility of different schools and their difficulty in successfully communicating with each other and combining their doctrines. None of these theories reflects realities in Vietnam (or China) past or present. The followers have no problem practicing the various teachings at the same time.
Theravada
As of 1997, there were 64 Theravada temples throughout the country, of which 19 were located in Hồ Chí Minh City and its vicinity. Besides Bửu Quang and Kỳ Viên temples, other well known temples are Bửu Long, Giác Quang, Tam Bảo (Đà Nẵng), Thiền Lâm and Huyền Không (Huế), and the large Sakyamuni Buddha Monument (Thích Ca Phật Đài) in Vũng Tàu.
Pure land
It was not until 2007 that Pure Land Buddhism, the most widespread type of Buddhism practiced in Vietnam, was officially recognized by the government.
The methods of Pure Land Buddhism are perhaps the most widespread within Vietnam. It is common for practitioners to recite sutras, chants and dharanis looking to gain protection through bodhisattvas or Dharma-Protectors. It is a devotional practice where those practicing put their faith into Amitabha Buddha (V. A Di Đà Phật). Followers believe they will gain rebirth in the Pure Land by chanting Amitabha’s name. The Pure Land is where one can more easily gain enlightenment since suffering does not exist. Many religious organizations have not been recognized by the government however in 2007, with 1.5 million followers, The Vietnamese Pure Land Buddhism Association (Tịnh Độ Cư Sĩ Phật Hội Việt Nam ) received official recognition as an independent and legal religious organization.
Thiền Tông/Zen School
Thiền is the Vietnamese name for the school of Zen Buddhism. Thiền Tông, or the "Zen school", is derived from the Chinese Chan-zong, in which Chan derivatives of the Sanskrit "Dhyāna". The traditional account is that in 580 CE, an Indian monk named Vinitaruci (Vietnamese: Tì-ni-đa-lưu-chi) traveled to Vietnam after completing his studies with Jianzhi Sengcan, the third patriarch of Chinese Zen. This would be the first appearance of Vietnamese Zen, or Thien (thiền) Buddhism. The sect that Vinitaruci and his lone Vietnamese disciple founded would become known as the oldest branch of Thien. After a period of obscurity, the Vinitaruci School became one of the most influential Buddhist groups in Vietnam by the 10th century, particularly under the patriarch Vạn-Hạnh (died 1018). Other early Vietnamese Zen schools included the Vo Ngon Thong (Vô Ngôn Thông), which was associated with the teaching of Mazu, and the Thao Duong (Thảo Đường), which incorporated nianfo (niem phat/Pure Land) chanting techniques; both were founded by Chinese monks.
A new Thiền school was founded by King Trần Nhân Tông (1258–1308); called Trúc Lâm (Bamboo Forest/Grove) school, which evinced a deep influence from Confucian and Taoist philosophy. Nevertheless, Trúc Lâm's prestige waned over the following centuries as Confucianism became dominant in the royal court. In the 17th century, a group of Chinese monks led by Nguyên Thiều introduced the Lâm Tế school. A more domesticated offshoot of Lâm Tế, the Liễu Quán school, was founded in the 18th century and has since been the predominant branch of Vietnamese Zen.
Some scholars argue that the importance and prevalence of Zen (Thiền) in Vietnam has been greatly overstated, and that Zen has played more of an elite rhetorical role than a role of practice. The Thiền Uyển Tập Anh (Outstanding Figures in the Vietnamese Zen Community) has been the dominant text used to legitimize the Zen Buddhist lineage and history within Vietnam. However Cuong Tu Nguyen’s “Zen in Medieval Vietnam: A Study and Translation of the Thien Tap Anh” (1997) gives a critical review of how the text has been used to create a history of Zen Buddhism that, in his own view, is “fraught with discontinuity”. According Cuong Tu Nguyen, current day Buddhist practices are not reflective of a Zen past in that in modern day Vietnam the common practices are more focused on ritual and devotion than the Zen focus on meditation.
Nonetheless, we are seeing an increased population in Zen today. Two figures who have been responsible for this increased interest in Thien is Thich Nhat Hanh, currently residing in France, and Thich Thanh Tu, who lives in Da Lat.
The most famous practitioner of synchronized Thiền Buddhism in the West is Thích Nhất Hạnh who has authored dozens of books and founded Dharma center Plum Village in France together with Bhiksuni Chân Không. According to Nguyen and Barber, Thich Nhat Hanh’s fame in the Western world as a proponent of engaged Buddhism and a new zen style has “no affinity with or any foundation in traditional Vietnamese Buddhist practices” and according to Alexander Soucy (2007) his style of Zen Buddhism is not reflective of actual Vietnamese Buddhism. Thich Nhat Hanh’s Buddhist teachings have started to return to a Vietnam where the Buddhist landscape is now being shaped by the combined Vietnamese and Westernized Buddhism that is focused more on the meditative practices.
