Tendai (天台宗), also known as the Tendai Lotus School (天台法華宗 Tendai hokke shū, sometimes just "hokke shū") is a Mahāyāna Buddhist tradition (with significant esoteric elements) officially established in Japan in 806 by the Japanese monk Saichō (posthumously known as Dengyō Daishi). The Tendai school, which has been based on Mount Hiei since its inception, rose to prominence during the Heian period (794-1185). +more
By the Kamakura period (1185-1333), Tendai had become one of the dominant forms of Japanese Buddhism, with numerous temples and vast landholdings. During the Kamakura period, various monks left Tendai (seeing it as corrupt) to establish their own "new" or "Kamakura" Buddhist schools such as Jōdo-shū, Nichiren-shū and Sōtō Zen. +more
In Chinese and Japanese, its name is identical to Tiantai, its parent school of Chinese Buddhism. Both traditions emphasize the importance of the Lotus Sutra and revere the teachings of Tiantai patriarchs, especially Zhiyi. +more
Other unique elements include an exclusive use of the bodhisattva precepts for ordination (without the pratimoksha), a practice tradition based on the "Four Integrated Schools" (Pure Land, Zen, Mikkyo and Precepts), and an emphasis on the study of Chinese Esoteric Buddhist sources. +more
History
Foundation by Saichō
Although Jianzhen (Jp. Ganjin) had brought Tiantai teachings to Japan as early as 754, its teachings did not take root until generations later when the monk Saichō 最澄 (767-822) joined the Japanese missions to Imperial China in 804 and founded Enryaku-ji on Mount Hiei. +more
From the city of Ningbo (then called Míngzhōu 明州), Saichō was introduced by the governor to Dàosuì (道邃), who was the seventh Tiantai patriarch, and later he journeyed to Tiantai Mountain for further study. After receiving teachings and initiations on Chan, Precepts and Chinese Esoteric Buddhism, Saichō devoted much of his time to making accurate copies of Tiantai texts and studying under Dàosuì. +more
Because of the Imperial Court's interest in Tiantai as well as esoteric Buddhism, Saichō quickly rose in prominence upon his return. He was asked by Emperor Kanmu (735-806) to perform various esoteric rituals, and Saichō also sought recognition from the Emperor for a new, independent Tendai school in Japan. +more
The new Tendai school was therefore based on a combination of the doctrinal and meditative system of Zhiyi with esoteric Buddhist practice and texts. Tendai learning at Mount Hiei traditionally followed two curriculums:
* Shikan-gō 止觀業: Exoteric practice, mainly based on Zhiyi's Mohezhiguan * Shana-gō 遮那業: Esoteric Buddhism, focused on the Mahāvairocana-sūtra and other tantric works
However, Emperor Kanmu died shortly thereafter, and Saichō was not allocated any ordinands until 809 with the reign of Emperor Saga. Saichō's choice of establishing his community at Mount Hiei also proved fortuitous because it was located to the northeast of the new capital of Kyoto and thus was auspicious in terms of Chinese geomancy as the city's protector.
Disagreements with other schools
The remainder of Saichō's life was spent in heated debates with notable Hossō figures, particularly Tokuitsu, and maintaining an increasingly strained relationship with Kūkai (from whom he received esoteric initiations) to broaden his understanding of esoteric Buddhism. The debates with the Hossō school was primarily centered on the doctrine of the One Vehicle (ekayana) found in the Lotus Sutra which the Hossō school saw as not being an ultimate teaching. +more
Saichō also studied esoteric Buddhism under Kūkai, the founder of the Shingon school. Saichō borrowed esoteric texts from Kūkai for copying and they also exchanged letters for some time. +more
Saichō's efforts were also devoted to developing a Mahāyāna ordination platform that required the Bodhisattva Precepts of the Brahmajala Sutra only, and not the pratimokṣa code of the Dharmaguptaka vinaya, which was traditionally used in East Asian Buddhist monasticism. Saichō saw the precepts of the small vehicle (hinayana) as no longer being necessary. +more
Development after Saichō
Seven days after Saichō died, the Imperial Court granted permission for the new Tendai Bodhisattva Precept ordination process which allowed Tendai to use an ordination platform separate from the powerful schools in Nara. Gishin, Saichō's disciple and the first "zasu" (座主), presided over the first allotted ordinands in 827. +more
By 864, Tendai monks were now appointed to the powerful
(僧綱) with the naming of An'e (安慧) as the provisional vinaya master. Other examples include Enchin's appointment to the Office of Monastic Affairs in 883. +more
Development of Tendai practice and esotericism
Philosophically, the Tendai school did not deviate substantially from the beliefs that had been created by the Tiantai school in China. However, Saichō had also transmitted numerous teachings from China was not exclusively Tiantai, but also included Zen (禪), Pure Land, the esoteric Mikkyō (密教), and Vinaya School (戒律) elements. +more
After Saichō, the Tendai order underwent efforts to deepen its understanding of teachings collected by the founder, particularly esoteric Buddhism. Saichō had only received initiation in the Diamond Realm Mandala, and since the rival Shingon school under Kūkai had received deeper training, early Tendai monks felt it necessary to return to China for further initiation and instruction. +more
However, in later years, this range of teachings began to form sub-schools within Tendai Buddhism. By the time of Ryōgen, there were two distinct groups on Mt. +more
Sōō 建立大師相應 (831-918), a student of Ennin, is another influential Tendai figure. He is known for developing the ascetic practice circumambulating Mt. +more
Akaku Daishi Annen 阿覺大師安然 (841-902?) is one of the most important post-Saichō Tendai thinkers. He wrote around a hundred works on Tendai doctrine and practice. +more
According to Lucia Dolce, Annen "systematized earlier and contemporary doctrines elaborated in both streams of Japanese esoteric Buddhism, Tōmitsu (i. e. +more
These various post-Saichō Tendai figures also developed the Tendai doctrine of "the identity of the purport of Perfect and Esoteric teachings" (enmitsu itchi 円密一致) which according to Ōkubo Ryōshun "refers to the harmony and agreement between the Perfect teachings of the Lotus Sutra and Esoteric Buddhism."
Ryōgen 良源 (912-985) was the 18th abbot of the head temple Enyrakuji at Mount Hiei. He was an influential politician closely tied to the Fujiwara clan as well as a scholar. +more
Genshin 惠心僧都源信 (942-1017), a student of Ryōgen, wrote the famous Ōjōyōshū 往生要集 ("Essentials of Birth in the Pure Land"), a treatise on Pure Land practice which influenced later Pure Land Japanese figures.
Medieval Japan (12th-16th century)
Although the Tendai sect flourished under the patronage of the Imperial House of Japan and the noble classes, by the end of the Heian period, it experienced an increasing breakdown in monastic discipline, plus political entanglements with rival factions of the Genpei War, namely the Taira and Minamoto clans. Due to its patronage and growing popularity among the upper classes, the Tendai sect became not only respected, but also politically and even militarily powerful, with major temples having vast landholdings and fielding their own monastic armies of sōhei (warrior-monks). +more
In response to the perceived worldliness of the powerful Tendai school, a number of low-ranking Tendai monks became dissatisfied and sought to establish independent schools of their own. The major figures of "New Kamakura Buddhism" like Nichiren, Hōnen, Shinran, Eisai and Dōgen-all famous thinkers in non-Tendai schools of Japanese Buddhism-were all initially trained as Tendai monks. +more
Although a number of breakaway schools rose during the Kamakura period, the Tendai school used its patronage to try to oppose the growth of these rival factions-particularly Nichiren Buddhism, which began to grow in power among the merchant middle class, and Pure Land Buddhism, which eventually came to claim the loyalty of many of the lower classes. Enryaku-ji, the temple complex on Mount Hiei, became a sprawling center of power, attended not only by ascetic monks, but also by brigades of sōhei (warrior monks) who fought in the temple's interest. +more
Kamakura period Tendai also produced a number of important figures of its own, including Jien 慈圓 (1155-1225), known as a historian and a poet, who wrote the Gukanshō (a religious history of Japan) and numerous devotional poems. Other important figures include Shōshin 證眞 (fl. +more
Hōjibō Shōshin 寶地房證眞 (active 1153-1214) was a major Buddhist intellectual in medieval Japanese Buddhism and the head of the Tendai curriculum at Mount Hiei. Shōshin wrote numerous works and commentaries, and is most known for his commentaries on the writings of Zhiyi, the Personal Notes on the Three Major Works of Tendai (Tendai sandaibu shiki 天台三大部私記). +more
Worldview
According to Jiko Hazama, the Tendai Buddhist worldview advocates a comprehensive form of Buddhism which sees all Buddhist teachings as being unified under an inclusive reading of the ekayāna teaching of the Lotus Sutra. This holistic and inclusive form of Buddhism is based on the doctrinal synthesis of Tiantai Zhiyi, which was ultimately based on the Lotus Sutra.
Tendai Buddhism has several philosophical insights which allow for the reconciliation of Buddhist doctrine with aspects of Japanese culture such as Shinto and Japanese aesthetics. These include Zhiyi's theory of perfect interfusion or unity of all phenomena (expressed in teachings like ichinen sanzen "three thousand realms in one thought") and the Tendai theory of hongaku (original enlightenment) which holds that enlightenment is intrinsic in all things. +more
In the major Tendai institutions like Taisho University and Mount Hiei, the main subjects of study are the Lotus Sutra, the works of the Tiantai Patriarch Zhiyi, the works of the founder Saichō and some later Tendai figures like Ennin.
The Lotus Sutra and Classic Tiantai Thought
The thought of the Japanese Tendai school is founded on the classic Chinese Tiantai doctrines found in the works of patriarch Zhìyǐ. These include:
* The One Vehicle of the Lotus Sutra, * The Three Truths, * The Three Samadhis, * The Five Periods and Eight Teachings, * The Four Siddhanta, * "Three Thousand Realms in a Single Thought Moment" (ichinen sanzen 一念三千). Tendai Buddhism reveres the Lotus Sutra as the highest teaching in Buddhism. +more
Saichō taught that there were "three kinds of Lotus Sutra". According to Jacqueline Stone, these can be explained as follows:
* The Fundamental Lotus: "the one vehicle which represents the Buddha's single compassionate intent, underling all his teachings, to lead all beings to buddhahood. " * The Hidden and Secret Lotus: "those teachings in which, due to the immaturity of the Buddha's audience, this intention is not outwardly revealed. +more
Stone writes that Saicho saw all Buddhist teachings as being the true "Lotus Sutra" and he therefore attempted to integrate all Buddhist teachings he had studied within a single framework based on the Lotus Sutra's One Vehicle.
Hazama Jikō writes that the central feature of Tendai thought is its advocacy of the “One Great Perfect Teaching” (一大円教), "the idea that all the teachings of the Buddha are ultimately without contradiction and can be unified in one comprehensive and perfect system. " This idea was used by Saichō as a basis for his integration of the various schools of Buddhism into a single comprehensive synthesis. +more
Saichō believed that by consolidating all Buddhist ideas and practices and including all the varieties of Buddhism, his new school would allow all to "enter the great sea of Thusness which has a single flavor" (真如一味の大海) by following the path of goodness and that this would protect the nation. According to Hazama Jikō "these themes run throughout Saichō's work" including his Hokke shuku 法華秀 句 and Shugo kokkai sho 守護国界章.
Tendai thought also vigorously defends the idea that all beings have the potential for full buddhahood and thus that the Lotus Sutra was a teaching for all sentient beings. This teaching in particular was a major point of contention with the Japanese Hossō (Yogacara) school in Japan who espoused the Five Categories of Beings (Five Natures Doctrine) which argues that not all being can become Buddhas, since some do not have the seeds for Buddhahood. +more
Doctrinal classification
Tendai thought also frames its understanding of Buddhist practice on the Lotus Sutra's teaching of upāya or (方便). Furthermore, Tendai uses a similar hierarchy as the one used in Chinese Tiantai to classify the various other sutras in the Buddhist canon in relation to the Lotus Sutra, and it also follows Zhiyi's original conception of Five Periods Eight Teachings or
gojihakkyō
(五時八教). This is based on the doctrine of expedient means, but was also a common practice among East Asian schools trying to sort the vast corpus of writing inherited from India.
Annen provided a new doctrinal classification system (based on Zhiyi's system) for Japanese Tendai. All Buddhist teachings are seen as being included into the following categories. +more
* The Tripiṭaka teachings (zō 藏), i. e. +more
The highest teachings are those who derive from the one vehicle:
* The Perfect Tendai teaching, derived from the Lotus Sutra, and the Avataṃsaka-sūtra (en 圓) * The Esoteric teachings (mitsu 密)
Buddhahood with this very body
Another important doctrine in Japanese Tendai is that it is possible to attain "Buddhahood with this very body" (sokushin jōbutsu). This is closely related to the idea of original enlightenment. +more
Later Tendai scholars like Rinshō, and Annen were much more optimistic about the possibility of Buddhahood in this very body and claimed certain esoteric practices could lead to Buddhahood rapidly in only one lifetime, while de-emphasizing the concern with achieving Buddhahood in future lives. They also further extended the application of this idea to individuals at the lower bodhisattva levels of the degrees of identity schema and also argued that one could jump over bodhisattva stages. +more
However, other Tendai figures like Hōjibō Shōshin (1136-1220 or 1131-1215), an important Tendai commentator on Zhiyi's works, were more traditional and critical of ideas concerning the rapid realization of Buddhahood for everyone (without denying the possibility of Buddhahood in this body). For Shōshin, sokushin jōbutsu applied to those who had "superior religious faculties" because they "have previously practiced the various provisional teachings" in many previous lives.
Hongaku
The Tendai school was the locus of the development of the Japanese doctrine of hongaku 本覚 (innate or original enlightenment), which holds that all beings are enlightened inherently and which developed in Tendai from the cloistered rule era (1086-1185) through the Edo period (1688-1735). According to Jacqueline Stone, the term “original enlightenment” itself (Chn. +more
Stone writes that the medieval Tendai doctrine regards "enlightenment or the ideal state as inherent from the outset and as accessible in the present, rather than as the fruit of a long process of cultivation. " Scholars also refer to the doctrinal system associated with this idea as "original enlightenment thought". +more
Hongaku teachings were passed down through various exoteric teaching lineages (which often involved secrecy), the largest of which were the Eshin-ryu and the Danna-ryu. At the core of these doctrinal systems was the Tendai practice of the "threefold contemplation in a single thought" (isshin sangan 一心 三観) which is taught in Zhiyi's Mohezhiguan. +more
While certain scholars have seen hongaku thought as denying the need for Buddhist practice, Stone notes that Tendai hongaku based texts like the Shinnyokan 真 如 観 (Contemplation of true suchness) and the Shuzenji-ketsu 修 禅 守 伏 (Decisions of Hsiuch’an-ssu) deny this idea. Instead, these texts teach various kinds of Buddhist practices, including nenbutsu, contemplation of emptiness (kukan 空観), meditations using Buddhist icons and mirrors, practicing the threefold contemplation in the midst of daily activities and recitation of the daimoku during when one is approaching death.
Hongaku thought was also influential on the development of New Kamakura Buddhism and the founders of these schools, though they had their own unique understandings. However, not all Tendai thinkers embraced hongaku thought. +more
Practice
Tendai Practice Theory
A feature unique to Japanese Tendai Buddhism from its inception was the concept of shishūyūgō (四宗融合). Senior Tendai teachers, or ajari, train in all four practice traditions.
Under the umbrella of the Lotus Sutra, Tendai integrates four main aspects of Mahayana Buddhist practice: * Pure Land practices, especially the recitation of the Buddha's name (nembutsu), such as the name of Amitabha * Śamatha-vipaśyanā meditation (Jp. shikan 止観, "calming-insight" meditation). +more
taimitsu
台密. * Precepts, in particular the Bodhisattva Precepts.
According to Saichō and other later Tendai scholars, the Perfect teaching of the Lotus Sutra and the tantric doctrines and practices of Esoteric Buddhism had the same ultimate intent. This view of the equality and compatibility between the Tiantai Lotus teachings and Esoteric Buddhism was important for Saichō. +more
Certain later Tendai figures like Ennin also argued that esoteric practices led to Buddhahood faster than exoteric (non-esoteric) practices and some (such as Annen) argued that they were the only way to full Buddhahood. These figures also often saw the Lotus Sutra (which refers itself as "the secret essential of the buddhas" and "the secret treasure of the Tathagatha") as an esoteric text and this view has some precedent in the Chinese Tiantai tradition.
However, other more conservative figures like Hōjibō Shōshin rejected the idea that esoteric Buddhism is higher or superior to Tendai Mahayana practice, since both of these traditions are ultimately founded on the middle way and both teach the contemplation of the emptiness of dharmas. Shōshin held that mantras and other esoteric practices were merely another skillful means for contemplating the middle way and are thus different expressions of the same principle. +more
Pure Land practice
Practices related to and veneration of Amitābha and his Sukhavati in the Tendai tradition began with Saichō's disciple, Ennin. After journeying to China for further study and training, he brought back a practice called the "five-tone nembutsu" or goe nenbutsu (五会念仏), which was a form of intonation practiced in China for reciting the Buddha's name. +more
However, both meditation on the Pure Land (kansō nenbutsu 観想念仏) and recitation of the Buddha's name (shōmyō nenbutsu 称名念仏) became an integral part of Pure Land practices in the Tendai tradition. In addition to the five-tone nembutsu brought back from China, Ennin also integrated a special monastic training program called the jōgyō zanmai (常行三昧) originally promulgated by Zhiyi. +more
In addition to increasing monastic practices related to the Pure Land, monks also taught Pure Land practices to the lay community in the form of reciting the Buddha's name. The most famous of these nenbutsu hijiri (念仏聖) was a monk named Kūya (空也, 903-972).
Pure Land Buddhist thought was further developed by a Tendai monk named Genshin (源信, 942-1017) who was a disciple of Ryōgen, the 18th chief abbot or zasu (座主) of Mount Hiei. Genshin wrote an influential treatise called Ōjōyōshū (往生要集), which vividly contrasted the Sukhavati Pure Land of Amitābha with the descriptions of the hell realms in Buddhism. +more
Finally, Pure Land practices in Tendai were further popularized by former Tendai monk Hōnen, who established the first independent Pure Land school, the Jōdo-shū, and whose disciples carried the teachings to remote provinces in one form or another. This includes another ex-Tendai monk named Shinran, who eventually established the related Jōdo Shinshū.
Tendai Esotericism (Taimitsu)
One of the adaptations by the Tendai school was the introduction of esoteric Buddhist practice into Tendai Buddhism. This was originally known as “the shingon (or mikkyō) of the Tendai lineages” and was later named Taimitsu "Tendai Esotericism" (台密), distinguishing it from the Shingon (Mantra) school, which is known as “Tōmitsu” (東密, literally, “the esotericism of the Tōji lineages”).
Taimitsu claims that through the chanting of mantras, maintaining mudras, and performing certain meditations using mandalas (known as "the three mysteries"), one is able to see that the sense experiences are the teachings of Buddha, have faith that they are inherently an enlightened being, and can attain buddhahood within this very body. Eventually, these esoteric rituals came to be considered of equal importance with the teachings of the Lotus Sutra, which was also seen as an esoteric sutra (but only "in principle", not "in practice", since it did not include the practice of the three mysteries).
The origins of Taimitsu are found in Chinese Esoteric Buddhism similar to the lineage of Kūkai, and Saichō's disciples were encouraged to study under him. As a result, Tendai esoteric ritual bears much in common with Shingon, though the underlying doctrines differ. +more
Some Taimitsu scholars, like Ennin, classify esoteric scriptures into two classes: those containing the principles of esoteric Buddhism (i. e. +more
Bodhisattva precepts
The Tendai school's ethical teachings focus exclusively on the Bodhisattva Precepts (C. pusajie, J. +more
The bodhisattva precepts in Tendai are all said to rely on three types of “pure precepts” (sanjujokai 三聚浄戒):
* Precepts against doing evil deeds, such as murder, theft, pride, anger, and so forth (sho ritsugi kai 摂律 儀 戒) * Precepts encouraging good activity, for benefiting oneself (sho zenbo kai 摂菩法戒) * Precepts encouraging activity which will benefit others (sho shujo kai 摂衆生戒 )
According to Hazama Jikō:The first category includes the prohibitions against the ten major and forty-eight minor transgressions as explained in the Bonmokyo 梵辋経 (T24, 997-1010). It also includes general restrictions against any kind of evil activity, whether physical, verbal, or mental. +more
The bodhisattva precepts were seen as being based on the Lotus Sutra's teaching that all beings have the potential for Buddhahood and that they have a fundamental goodness, or Buddha-nature. This was the fundamental ethical teaching for Tendai thought. +more
Zen
Saichō also received Chan (Zen) teachings in China from the Oxhead (Jp. Gozu) school and Northern schools integrated them into his Tendai system. +more
Some of the views of Saichō regarding the Mahayana precepts were drawn from the Tiantai masters Huisi and Daosui and the teachings Chan masters like Bodhidharma, Dao-xuan (Dōsen, especially his commentary on the Brahmā's Net Sūtra) and Daoxin (Dōshin, particularly his “Manual of Rules of Bodhisattva Precepts”). Lin, Pei‐Yin (2011) Precepts and lineage in Chan tradition: cross‐cultural perspectives in ninth century East Asia, pp. +more
These Chinese Chan masters emphasized formless practice (無相行) or attribute-less practice also known as anrakugyō (Ch. anlexing 安樂行, serene and pleasing activities), both in Chan meditation and in precept training. +more
These various Chinese ideas about the integration of practice and precepts were integrated into Saichō's view of the “Perfect and Sudden Precepts” (Endonkai). Lin, Pei‐Yin (2011) Precepts and lineage in Chan tradition: cross‐cultural perspectives in ninth century East Asia, p. +more
Tendai and Shinto
Tendai doctrine allowed Japanese Buddhists to reconcile Buddhist teachings with the native religious beliefs and practices of Japan (now labeled "Shinto"). In the case of Shinto, the difficulty is the reconciliation of the pantheon of Japanese gods (kami), as well as with the myriad spirits associated with places, shrines or objects, with Buddhist teachings. +more
Sannō Shintō 山王ネ申道 was a specifically Tendai branch of sryncretic Buddhist-Shinto religious practice, which revered kamis called the Mountain Kings (Sannō) or Sanno Sansei 山王ニ聖 (The Three Sacred [Deities] of Sanno) and was based on Hie Taisha 日吉大社 a shrine on Mount Hiei. The Togakushi Shrine (戸隠神社, Togakushi Jinja) was also associated with the Tendai school before it was separated from Buddhist institutions by the Japanese state during the separation of Shinto from Buddhism in the 19th century.
These religious ideas eventually led to the development of a Japanese current of thought called honji suijaku (本地垂迹), which argued that kami are simply local manifestations (the suijaku or "traces") of the Buddhas (honji, "true nature"). This manifestation of the Buddhas was explained through the classic Mahayana doctrines of skillful means and the Trikaya.
Shugendō
Some Tendai Buddhist temples and mountains are also sites for the practice of the syncretic Shugendō tradition. Shugendō is a mountain ascetic practice which also adopted Tendai and Shingon elements. +more
Art and aesthetics
The classic Buddhist understanding of the Four Noble Truths posits that craving for pleasure, worldly desire and attachment must be cut off to put an end to suffering (dukkha). In early Buddhism, the emphasis, especially for monastics, was on avoiding activities that might arouse worldly desires, including many artistic endeavors like music and performance arts. +more
However, later Mahayana views developed a different emphasis which embraced all the arts. In Japan, certain Buddhist rituals (which were also performed in Tendai) grew to include music and dance, and these became very popular with the people. +more
Another influential poet monk from the Tendai tradition was Fujiwara no Shunzei (1114-1204). His son, Fujiwara no Teika was also influenced by the classic Tendai thought of Zhiyi. +more
