Pure Land Buddhism in the context of "Tan-luan"

East Asian Buddhism or East Asian Mahayana is a collective term for the schools of Mahāyāna Buddhism which developed across East Asia and which rely on the Chinese Buddhist canon. These include the various forms of Chinese, Japanese, Korean, and Vietnamese Buddhism. East Asian Buddhists constitute the numerically largest body of Buddhist traditions in the world, numbering over half of the world's Buddhists.

East Asian forms of Buddhism all derive from the sinicized Buddhist schools which developed during the Han dynasty and the Song dynasty, and therefore are influenced by Chinese culture and philosophy. The spread of Buddhism to East Asia was aided by the trade networks of the Silk Road and the missionary work of generations of Indian and Asian Buddhists. Some of the most influential East Asian traditions include Chan (Zen), Nichiren Buddhism, Pure Land, Huayan, Tiantai, and Chinese Esoteric Buddhism. These schools developed new, uniquely East Asian interpretations of Buddhist texts and focused on the study of Mahayana sutras. According to Paul Williams, this emphasis on the study of the sutras contrasts with the Tibetan Buddhist attitude which sees the sutras as too difficult unless approached through the study of philosophical treatises (shastras).

Buddhism was first established in Japan in the 6th century CE. Most of the Japanese Buddhists belong to new schools of Buddhism which were established in the Kamakura period (1185－1333). During the Edo period (1603–1868), Buddhism was controlled by the feudal Shogunate. The Meiji period (1868–1912) saw a strong response against Buddhism, with persecution and a forced separation between Buddhism and Shinto (Shinbutsu bunri).

The largest sects of Japanese Buddhism are Pure Land Buddhism with 22 million believers, followed by Nichiren Buddhism with 10 million believers, Shingon Buddhism with 5.4 million, Zen Buddhism with 5.3 million, Tendai Buddhism with 2.8 million, and only about 700,000 for the six old schools established in the Nara period (710－794).

Jōdo Shinshū (浄土真宗, "The True Essence of the Pure Land Teaching"), also known as Shin Buddhism or True Pure Land Buddhism, is a Japanese tradition of Pure Land Buddhism founded by Shinran (1173–1263). Shin Buddhism is the most widely practiced branch of Buddhism in Japan, and its membership is claimed to include 10 percent of all Japanese citizens. The school is based on the Pure Land teachings of Shinran, which are based on those of earlier Pure Land masters Hōnen, Shandao and Tanluan, all of whom emphasized the practice of nembutsu (the recitation of Amida Buddha's name) as the primary means to obtain post-mortem birth in the Pure Land of Sukhavati (and thus, Buddhahood).

Shinran taught that enlightenment cannot be realized through one’s own self-power (jiriki), whether by moral cultivation, meditation, or ritual practice, but only through the other-power (tariki) of Amida Buddha’s compassionate Vow. Therefore, in Shin Buddhism, the nembutsu is not a meritorious deed or practice that produces merit and liberation, but an expression of joyful gratitude for the assurance of rebirth in the Pure Land, which has already been granted by Amida’s inconceivable wisdom and compassion. Doctrinally, Jōdo Shinshū is grounded in Shinran’s magnum opus, the Kyōgyōshinshō (Teaching, Practice, Faith, and Realization), which presents a comprehensive exegesis of Pure Land thought based on Indian and Chinese Mahāyāna sources. Shinran’s synthesis reframes the Pure Land path as the culmination of Mahāyāna Buddhism, emphasizing ideas like true faith (shinjin), other-power, the abandonment of self-power, the nembutsu of gratitude, and the all-embracing compassion of Amida Buddha's Original Vow.

Jōdo-shū (浄土宗, "The Pure Land School") is a Japanese branch of Pure Land Buddhism derived from the teachings of the Kamakura era monk Hōnen (1133–1212). The school is traditionally considered as having been established in 1175 and is the most widely practiced branch of Buddhism in Japan, along with Jōdo Shinshū. There are various branches of Jōdo-shū, which the largest and most influential ones being Chinzei-ha and Seizan-ha.

Jōdo-shū Buddhism focuses exclusively on devotion to Amitābha Buddha (Amida Nyorai), and its practice is focused on the Nembutsu (recitation of Amitābha’s name). As in other forms of Pure Land Buddhism, adherents believe that the faithful recitation of the phrase "Namu Amida Butsu" (Homage to Amida Buddha) results in birth in the pure land of Sukhavati.

Ippen Shōnin (一遍上人) 1234/9–1289 was a Japanese Buddhist itinerant preacher (hijiri) whose movement, the Ji-shū (時宗; "Time sect") became one of the major currents of medieval Japanese Pure Land Buddhism. Born in modern Ehime Prefecture, he studied in the Seizan branch of Jōdo-shū before meeting with many Shingon and Tendai associated hijiri and then becoming a wandering holy man himself. During a pilgrimage to the Kumano Shrines, Ippen had an experience which inspired him to spread the Pure Land faith throughout Japan. Accompanied by bands of followers, he traveled throughout Japan teaching that salvation lay in the single-minded invocation of Amida’s Name and that the very moment of recitation unites the reciter with the timeless enlightenment of the Buddha. Ippen traveled over fifteen hundred miles, visiting every major population center and devotional center in Japan, such as Kumano, Zenkōji, Taimadera, and Mt. Kōya.

In his itinerant ministry, Ippen combined the devotional recitation of the nembutsu with ecstatic dancing, and the distribution of ofuda (talismans) inscribed with Amida’s Name, which he handed to people as symbols of faith and rebirth in the Pure Land. His teachings blended the Pure Land ideal of Other-Power with Zen non-dualism and the folk religious practices of wandering ascetics. Rejecting all self-powered efforts and sectarian distinctions, Ippen held that the simple recitation of even a single nembutsu invariably linked one with Amida Buddha's enlightenment, assuring our birth in the Pure Land. Ippen’s radical vision of faith and his insistence that the heart can attain birth in the Pure Land while the body remains in this world gave rise to a popular movement that appealed to all social classes. His life is outlined in the Ippen Hijiri-e, a series of narrative painted scrolls which are the main historical source for his life and activities.

The Nianfo (Chinese: 念佛; pinyin: niànfó, alternatively in Japanese 念仏 (ねんぶつ, nenbutsu); Korean: 염불; RR: yeombul; or Vietnamese: niệm Phật) is a Buddhist practice central to East Asian Buddhism. The Chinese term nianfo is a translation of Sanskrit buddhānusmṛti ("recollection of the Buddha"), a classic Buddhist mindfulness (smṛti) practice.

Nianfo focused on the Buddha Amitābha is also the most important practice in Pure Land Buddhism. In the context of East Asian Pure Land practice, nianfo typically refers to the oral repetition of the name of Amitābha through the phrase "Homage to Amitabha Buddha" (Ch: 南無阿彌陀佛, Mandarin: Nāmó Āmítuófó, Jp: Namu Amida Butsu, Vn: Nam-mô A-di-đà Phật; from the Sanskrit: Namo'mitābhāya Buddhāya). It can also refer to that phrase itself, in which case it may also be called the nianfo, or "The Name" (Japanese: myōgō 名号).

Yuan Hongdao (Chinese: 袁宏道; pinyin: Yuán Hóngdào; Wade–Giles: Yüan Hung-tao, style name Zhonglang, 1568–1610) was a scholar-official and one of the greatest Chinese poets and littérateurs of the Ming Dynasty. He is also a well known author on Pure Land Buddhism.

Yuan Hongdao is one of the Three Yuan Brothers, along with his brothers Yuan Zongdao and Yuan Zhongdao. All were known for their literary writings influenced by Buddhism and Neo-Confucian Yangmingism. In Chinese Buddhism, Yuan is most famous for his Comprehensive Treatise on the West [Pure Land] (Xīfāng hélùn), an influential ten-fascicle work on Pure Land Buddhism.

Shinran (親鸞; Japanese pronunciation: [ɕiꜜn.ɾaɴ], May 21, 1173 – January 16, 1263) was a key Japanese Buddhist figure of the Kamakura Period who is regarded as the founder of the Jōdo Shinshū school of Japanese Buddhism. A pupil of Hōnen, the founder of the Japanese Pure Land movement, Shinran articulated a distinctive Pure Land vision that emphasized faith and absolute reliance on Amida Buddha’s other-power.

While Shinran trained as a Tendai monk on Mount Hiei, he lived much of his life as a married Buddhist teacher unlike other Kamakura Buddhist reformers, and he described himself as "neither monk nor layman". Shinran's major work, the Kyōgyōshinshō (Teaching, Practice, Faith, and Realization), is a systematic exposition and defense of Pure Land doctrine. Shinran taught that liberation arises from the entrusting mind (shinjin) awakened through Amida's compassionate power, not from any merit or power of one's own. His interpretation profoundly reshaped the course of Japanese Buddhism and continues to influence East Asian religious thought.

The Amitāyus Sutra (Sanskrit), simplified Chinese: 佛说无量寿经; traditional Chinese: 佛說無量壽經; pinyin: Fóshuō Wúliàngshòu Jīng; Sutra of Immeasurable Life Spoken by Buddha; Vietnamese: Phật Thuyết Vô Lượng Thọ Kinh; Japanese: Bussetsu Muryōju Kyō (Taisho Tripitaka no. 360), also known as the Longer Sukhāvatīvyūha Sūtra, is one of the two Indian Mahayana sutras which describe the pure land of Amitābha (also known as Amitāyus, "Measureless Life"). Together with the Sukhāvatīvyūha Sūtra, this text is highly influential in East Asian Buddhism. It is one of the three central scriptures of East Asian Pure Land Buddhism, and is widely revered and chanted by Pure Land Buddhists throughout Asia.

The title is often translated in English as either the Sutra [on the Buddha] of Immeasurable Life, or simply the Immeasurable Life Sutra.

The Amitābha Sūtra (Ch.: 阿彌陀經, pinyin: Āmítuó Jīng, or 佛說阿彌陀經, Fóshuō Āmítuó Jīng; Jp.: Amida Kyō, Vi.: A Di Đà Kinh), also known as the [Shorter] Sukhāvatīvyūha Sūtra (Sanskrit, The Array of "the Blissful Land", or The Arrangement of Sukhāvatī) is one of the two Indian Mahayana sutras that describe Sukhāvatī, the pure land of Amitābha. The text was translated into Chinese in 402 by Kumārajīva (Taishō Tripiṭaka no. 366) and it is also known in Chinese as the "Small Sutra" (Xiaojing).

The Amitābha Sūtra is highly influential in East Asian Buddhism, including China, Korea, Japan, and Vietnam since it is considered one of the "Three Pure Land" sutras which are the key scriptures in Pure Land Buddhism.
