Tiantai School

 Tiantai (Chinese and Japanese: 天台宗; pinyin: tiāntāi zōng; ) is an important school of Buddhism in China, Japan, Korea, and Vietnam. In Japan the school is known as Tendai-shū, and in Korea it is known as Cheontae.

The name is derived from the fact that Chih-i, the fourth Patriarch, lived on Mount Tiantai.Tiantai is sometimes also called "The Lotus School", after the central role of the Lotus Sutra in its teachings.

During the Tang Dynasty, the Tiantai school became one of the leading schools of Chinese Buddhism, with numerous large temples supported by emperors and wealthy patrons, with many thousands of Monks and millions of followers.

History
The Bodhisattva Avalokiteśvara, an important figure from the Lotus Sūtra.

Most scholars regard the Tiantai as one of the first truly Chinese schools of Buddhist Thought. The Schools of Buddhism that had existed in China prior to the emergence of the Tiantai are generally believed to represent direct transplantations from India, with little modification to their basic doctrines and methods. The creation of the Tiantai school signified the maturation and integration of Buddhism in the Chinese context. No longer content to simply translate texts received from Indian sources, Chinese Buddhists began to apply new analyses to old texts, and even to produce new scriptures and commentaries that would attain significant status within the East Asian sphere.

The Tiantai school became doctrinally broad, able to absorb and give rise to other movements within Buddhism. The tradition emphasized both scriptural study and Meditative practice, and taught the rapid Attainment of Buddhahood through observing the Mind.

The school is largely based on the teachings of Zhiyi, Zhanran, and Zhili, who lived between the 6th and 11th centuries in China. These teachers took an approach called "classification of teaching" in an attempt to harmonize the numerous and often contradictory Buddhist texts that had come into China. This was achieved through a particular interpretation of the Lotus Sūtra.
Patriarchs

Due to the use of Nāgārjuna's philosophy of the Middle Way, Nagarjuna is traditionally taken to be the first Patriarch of the Tiantai school.

The sixth century Dhyāna master Huiwen (慧文) is traditionally considered to be the second Patriarch of the Tiantai school. Huiwen studied the works of Nāgārjuna, and is said to have Awakened to the profound meaning of Nāgārjuna's words: "All conditioned Phenomena I speak of as empty, and are but false names which also indicate the mean."

Huiwen later transmitted his teachings to the Dhyāna master Huisi (Ch. 慧思, 515-577 CE), who is traditionally figured as the third Patriarch. During Meditation, he is said to have realized the Lotus Samādhi, indicating Enlightenment and Buddhahood. He authored the text Mahāyāna-śamatha-vipaśyanā.

Venerable Huisi then transmitted his teachings to Śramaṇa Zhiyi (Ch. 智顗, 538-597 CE), who is traditionally figured as the fourth Patriarch of Tiantai, who is said to have practiced the Lotus Samādhi and to have become Enlightened quickly. He authored many treatises such as explanations of the Buddhist texts, and especially systematic manuals of various lengths which explain and enumerate methods of Buddhist practice and Meditation. The above lineage was proposed by Buddhists of later times and do not reflect the popularity of the Monks at that time.
Zhiyi

Most scholars consider Zhiyi to have been the major founder of the Tiantai school, since he did the most to systematize and popularize the doctrines and methods associated with it. At a later date, the school's sixth Patriarch, Zhanran, would compose clarifying commentaries on Zhiyi's writings.

Zhiyi analyzed and organized all the Āgamas and Mahayana Sutras into a system of Five periods and eight types of teachings. For example, many elementary doctrines and bridging concepts had been taught early in The Buddha's advent when the vast majority of the people during his time were not yet ready to grasp the 'ultimate Truth'. These teachings (the Āgamas) were an upaya, or skillful means, were simply an example of The Buddha employing his boundless Wisdom to lead those people towards the Truth. Subsequent teachings delivered to more advanced followers thus represent a more complete and accurate picture of The Buddha's teachings, and did away with some of the philosophical 'crutches' introduced earlier. Zhiyi's classification culminated with the Lotus Sutra, which he held to be the supreme synthesis of Buddhist Doctrine. The difference on Zhiyi's explanation to the Golden Light Sutra caused a debate in Song Dynasty.
Texts

The Tiantai school takes the Lotus Sūtra (Saddharmapuṇḍarīka Sūtra) as the main basis, the MahāPrajñāpāramitā Śāstra of Nāgārjuna as the guide, the Nirvāṇa Sūtra as the support, and the Pañcaviṃśatisāhasrikā Prajñāpāramitā Sūtra for methods of contemplation.

In addition to its doctrinal basis in Indian Buddhist texts, the Tiantai school also emphasizes use of its own Meditation texts which emphasize the principles of śamatha and vipaśyanā. Of the Tiantai Meditation treatises, Zhiyi's Concise Śamatha-vipaśyanā (小止観), Mahā-śamatha-vipaśyanā (摩訶止観), and Six Subtle Dharma Gates (六妙法門) are the most widely read in China.[5] Rujun Wu identifies the work Mahā-śamatha-vipaśyanā of Zhiyi as the seminal Meditation text of the Tiantai school.
Classification of teachings

Tiantai classified The Buddha's teachings in Five periods and Eight teachings. This classification is usually attributed to Chih-i, but is probably a later development. The classification of teachings was also done by other schools, such as the Fivefold Classification of the Huayan school.
Five periods

The Five periods are Five periods in the LIFE OF THE BUDDHA in which he delivered different teachings, aimed at different audiences with a different level of understanding:

    The Period of Avatamsaka. During twenty-one days after his Enlightenment, The Buddha delivered the Avatamsaka Sutra.
    The Period of Agamas. During twelve years, The Buddha preached the Agamas for the Nihayana, including The Four Noble Truths and Dependent origination.
    The Period of Vaipulya. During eight years, The Buddha delivered the Mahayana teachings, such as the Vimalakirti Sutra, the ŚrīmāLādevī Sūtra, the Suvarnaprabhasa Sutra and other Mahayana Sutras.
    The Period of Prajna. During twenty-two years, The Buddha explained Emptiness in the Prajnaparamita-Sutras.
    The Period of Dharma-pundarik and Nirvana. In the last eight years, The Buddha preached the Doctrine of the One Buddha Vehicle, and delivered the Lotus Sutra and the Nirvana Sutra just before his Death.

Eight teachings

The Eight teachings consist of the Four Doctrines, and the Fourfold Methods.
Four Doctrines

    Tripitaka Teaching: the Sutra, Vinaya and ABHIDHAMMA, in which the basic teachings are explained
    Shared Teaching: the teaching of Emptiness
    Distinctive Teaching: aimed at the Bodhisattva
    Perfect Teaching - the Chinese teachings of the Lotus Sutra and the Avatamsaka Sutra

Fourfold Methods

    Gradual Teaching, for those with medium or inferior abilities
    Sudden Teaching, the Distinctive Teachings and the Complete Teaching for those with superior abilities
    Secret Teaching, teachings which are transmitted without the recipient being aware of it
    Variable Teaching, no fixed teaching, but various teachings for various persons and circumstances

Teachings

David Chappell lists the most important teachings as the doctrines of:

    The Threefold Truth,
    The Threefold Contemplation,
    The Fourfold Teachings,
    The Subtle Dharma,
    The Nonconceivable Discernment.

Nan Huaijin, a 20th-century Chán-teacher, summarizes the main teaching of the Tiantai school as the following:

    The One Vehicle (Skt. Ekayāna),
    The vehicle of attaining Buddhahood, as the main principle;
    The three forms of śamatha-vipaśyanā correlated with the Meditative perspectives of Emptiness,
    The mean, as the method of cultivating realization.

The Threefold Truth

The Tiantai school took up the principle of The Threefold Truth, derived from Nāgārjuna:

    Phenomena are empty of self-nature,
    Phenomena exist provisionally from a worldly perspective,
    Phenomena are both empty of existence and exist provisionally at once.

The transient World of Phenomena is thus seen as one with the unchanging, undifferentiated substratum of existence. This Doctrine of interpenetration is reflected in the Tiantai teaching of three thousand realms in a single moment of Thought.

The Threefold Truth has its basis in Nāgārjuna:

    All things arise through causes and conditions.

    That I declare as Emptiness.
    It is also a provisional designation.
    It is also the meaning of the Middle Path.

Three Contemplations

While the Three Truths are essentially one, they may be recognized separately as one undertakes the Three Contemplations:

    The first contemplation involves moving from the World of provisionality to the World of Emptiness, or Shunyata.
    The second contemplation is moving back from the World of Emptiness to the World of provisionality with an acceptance thereof.
    The third contemplation involves balancing the previous two by following the Middle Path.

The Fourfold Teachings

The Three Contemplations and Threefold Truth in turn Form the basis of the Fourfold Teachings, making them "parallel structures".
Meditation-practice

According to Charles Luk, in China it has been traditionally held that the Meditation methods of the Tiantai are the most systematic and comprehensive of all. Tiantai emphasizes śamatha and vipaśyanā Meditation.

Regarding the functions of śamatha and vipaśyanā in Meditation, Zhiyi writes in his work Concise Śamatha-vipaśyanā:

    The attainment of Nirvāṇa is realizable by many methods whose essentials do not go beyond the practice of śamatha and vipaśyanā. Śamatha is the first step to untie all bonds and vipaśyanā is essential to root out Delusion. Śamatha provides nourishment for the preservation of the knowing Mind, and vipaśyanā is the skillful Art of promoting Spiritual understanding. Śamatha is the unsurpassed cause of Samādhi, while vipaśyanā begets Wisdom.

The Tiantai school also places a great emphasis on Mindfulness of Breathing (Skt. ānāpānasmṛti) in accordance with the principles of śamatha and vipaśyanā. Zhiyi classifies breathing into four main categories:

    Panting (喘),
    Unhurried breathing (風),
    Deep and quiet breathing (氣),
    Stillness or rest (息).

Zhiyi holds that the first three kinds of breathing are incorrect, while the fourth is correct, and that the breathing should reach stillness and rest.
Influence

David Chappell writes that although the Tiantai school, "has the reputation of being...the most comprehensive and diversified school of Chinese Buddhism, it is almost unknown in the West" despite having a "religious framework that seemed suited to adapt to other cultures, to evolve new practices, and to universalize Buddhism". He attributes this failure of expansion to the school having "narrowed its practice to a small number of Rituals" and because it has "neglected the Intellectual breadth and subtlety of its founder".
