Early years (780–810)

Zongmi was born in 780 into the powerful and influential He (Chinese: 何) family in what is now central Sichuan. In his early years, he studied the Chinese classics, hoping for a career in the provincial government. When he was seventeen or eighteen, Zongmi lost his father and took up Buddhist studies. In an 811 letter to Chengguan, he wrote that for three years he "gave up eating meat, examined [Buddhist] scriptures and treatises, became familiar with the virtues of meditation and sought out the acquaintance of noted monks."^[3]

At the age of twenty-two, he returned to the Confucian classics and deepened his understanding, studying at the Yixueyuan (義學院) Confucian Academy in Suizhou. His later writings reveal a detailed familiarity with the Analects, the Classic of Filial Piety, and the Book of Rites, as well as historical texts and Daoist classics such as the works of Laozi.

Chan (804–810)

At the age of twenty-four, Zongmi met the Chan master Suizhou Daoyuan (Chinese: 遂州道圓; pinyin: Suìzhōu Dàoyuán^{[lower-alpha 1]} and trained in Chan for two or three years. He received Daoyuan's seal in 807, the year he was fully ordained as a Buddhist monk. Daoyuan was part of a southern Chan tradition called the Ching-chung school, which was based in Chengdu, Sichuan. This lineage goes back to the Korean prince and Chan master Kim Hwasang (also known as Wuxiang).^[4]

In his autobiographical summary, Zongmi states that it was the encounter with his master Daoyuan and with the Sutra of Perfect Enlightenment (Chinese: 圓覺經) that led him to enlightenment: "at one word [from Daoyuan] my mind-ground opened thoroughly, and with one scroll [of the Scripture of Perfect Enlightenment] its meaning was as clear and bright as the heavens."^[5]

Zongmi's sudden awakening during this period had a profound impact upon his subsequent scholarly career. He propounded the necessity of scriptural studies in Chan, and was highly critical of what he saw as the antinomianism of the Hongzhou lineage derived from Mazu Daoyi (Chinese: 馬祖道一; pinyin: Mǎzǔ Dàoyī; Japanese pronunciation: Baso Dōitsu, 709–788), which practiced "entrusting oneself to act freely according to the nature of one's feelings".^[6] But Zongmi's Confucian moral values never left him and he spent much of his career attempting to integrate Confucian ethics with Buddhism.^[7]

Huayan (810–816)

In 810, at the age of thirty, Zongmi met Lingfeng (Chinese: 靈峯), a disciple of the preeminent Buddhist scholar and Huayan exegete Chengguan (Chinese: 澄觀, 738–839). Lingfeng gave Zongmi a copy of Chengguan's commentary and subcommentary on the Avatamsaka Sutra. The two texts were to have a profound impact on Zongmi. He studied these texts and the sūtra with great intensity, declaring later that due to his assiduous efforts, finally "all remaining doubts were completely washed away." ^[8] In 812 Zongmi travelled to the western capital, Chang'an, where he spent two years studying with Chengguan, who was not only the undisputed authority on Huayan, but was also highly knowledgeable in Chan, Tiantai, the vinaya and East Asian Mādhyamaka.

Mount Zhongnan (816–828)

Zongmi withdrew to the Zhongnan Mountains southwest of Chang'an in 816 and began his writing career, composing an annotated outline of the Sutra of Perfect Enlightenment, and a compilation of passages from four commentaries on the sūtra. For the next three years Zongmi continued his research into Buddhism, reading through the Buddhist canon, the Tripiṭaka, and traveling to various temples on Zhongnan. He returned Chang'an in 819 and continued his studies utilizing the extensive libraries of various monasteries in the capital city. In late 819 he completed a commentary (Chinese: 疏; pinyin: shū) and subcommentary (Chinese: 鈔; pinyin: chāo) on the Diamond Sutra. In early 821 he returned to Cottage Temple (Chinese: 草堂寺; pinyin: Cǎotáng sì) beneath Gui Peak and hence became known as "Guifeng Zongmi".^[9] In mid-823, he finally finished his own commentary on the text that had led to his first awakening, Sutra of Perfect Enlightenment, and the culmination of a vow he had made some fifteen years earlier.^[10] For the next five years, Zongmi continued writing and studying in the Zhongnan Mountains as his fame grew.

Capital city (828–835)

He was summoned to the capital in 828 by Emperor Wenzong (r. 826–840) and awarded the purple robe and the honorific title "Great Worthy" (大德; dade; bhadanta). The two years he spent in the capital were significant for Zongmi. He was now a nationally honored Buddhist master with extensive contacts among the literati of the day. He turned his considerable knowledge and intellect towards writing for a broader audience rather than the technical exegetical works he had produced for a limited readership of Buddhist specialists. His scholarly efforts became directed towards the intellectual issues of the day and much of his subsequent work was produced at the appeals of assorted literati of the day.^[11] He began collecting every extant Chan text in circulation with the goal of producing a Chan canon to create a new section of the Buddhist canon. This work is lost but the title, Collected Writings on the Source of Chan (禪源諸詮集; Chanyuan zhuquanji) remains.^[12]

Last years (835–841)

It was Zongmi's association with the great and the powerful that led to his downfall in 835 in an event known as the Sweet Dew Incident. A high official and friend of Zongmi, Li Xun, in connivance with Emperor Wenzong of Tang and his general Zheng Zhu, attempted to curb the power of the court eunuchs by massacring them all. The plot failed and Li Xun fled to the Zhongnan Mountains, seeking refuge with Zongmi. Li Xun was quickly captured and executed and Zongmi was arrested and tried for treason. Impressed with Zongmi's bravery in the face of execution, the powerful eunuch Yu Hongzhi (Chinese: 魚弘志; pinyin: Yú Hóngzhì) persuaded fellow powerful eunuch Qiu Shiliang to spare Zongmi.^[13]

Nothing is known about Zongmi's activities after this event. Zongmi died in the zazen posture on 1 February 841 in Chang'an. He was cremated on 4 March at Guifeng temple. Twelve years later he was awarded the posthumous title "Samādhi-Prajñā Dhyāna Master" and his remains were interred in a stupa called Blue Lotus.^{[lower-alpha 2]}

Influence

Zongmi's work continued to be studied by later Chinese Buddhists. His ecumenical vision of Chan as a single family with many branches and his account of Tang Chan lineages were influential sources for later Song dynasty Chan works.^[14] His work was also very influential on the "Huayan-Chan" traditions of the Khitan Liao Empire (916-1125) and the Tangut kingdom (1038-1227) of the Western Xia.^[15]

Zongmi was especially influential on Korean Buddhism, due to his importance for Jinul's (1158-1210) system. Zongmi's thought continues to be influential on modern Korean Seon, and his ideas continue to be a major topic of debate today.^[14]

Confucianism, Daoism, Buddhism

Much of Zongmi's work was concerned with providing a dialogue between the three religions of China: Confucianism, Daoism and Buddhism. He saw all three as expedients, functioning within a particular historical context and although he placed Buddhism as revealing the highest truth of the three, this had nothing to do with the level of understanding of the three sages, Confucius, Laozi and Buddha, (who Zongmi saw as equally enlightened) and everything to do with the particular circumstances in which the three lived and taught.^[19][20] As Zongmi said:

Since encouraging the myriad practices, admonishing against evil, and promoting good contribute in common to order, the three teachings should all be followed and practiced. [However] if it be a matter of investigating the myriad phenomena, exhausting principle, realizing the nature, and reaching the original source, then Buddhism alone is the ultimate judgment.^[21]

Zongmi's early training in Confucianism never left him and he tried to create a syncretic framework where Confucian moral principles could be integrated within the Buddhist teachings.^[22]

Sudden and Gradual Enlightenment

Zongmi tried to harmonize the different views on the nature of enlightenment. For the Chan tradition, one of the major issues of the day was the distinction between the Northern line, which allegedly advocated a "gradual enlightenment" and the Southern line's rhetorics of "sudden enlightenment".

Coming from the Southern Chan tradition, Zongmi advocated the Southern teachings of sudden enlightenment. But he also saw both as according with the teachings of the Buddha. He wrote:

It is only because of variations in the style of the World Honoured One’s exposition of the teachings that there are sudden expositions in accordance with the truth and gradual expositions in accordance with the capacities [of beings]…this does not mean that there is a separate sudden and gradual [teaching].^[23]

Although the sudden teaching reveals the truth directly, and results in a "sudden" understanding that all beings are Buddhas, this does not mean that one attained Buddhahood rightaway. Hence, Zongmi advocated "sudden enlightenment" followed by "gradual cultivation". This gradual cultivation was to eliminate all remaining traces of defilements of the mind, that prevented one from fully integrating one's intrinsic Buddha-nature into actual behavior.^[24]) According to Zongmi:

"In terms of the elimination of hindrances, it is like when the sun immediately comes out, yet the frost melts gradually. With respect to the perfection of virtue, it is like a child which, when born, immediately possesses four limbs and six senses. As it grows, it gradually develops control over its actions. Therefore, the Hua Yen [Avatamsaka sutra] says that when the bodhicitta is first aroused, this is already the accomplishment of perfect enlightenment."^[25]

To explain this, Zongmi also used the metaphor of water and waves found in the Awakening of Faith treatise. The essential tranquil nature of water which reflects all things (intrinsic enlightenment) is disturbed by the winds of ignorance (un-enlightenment, delusion). Although the wind may stop suddenly (sudden enlightenment), the disturbing waves subside only gradually (gradual cultivation) until all motion ceases and the water once again reflects its intrinsic nature (Buddhahood). However, whether disturbed by ignorance or not, the fundamental nature of the water (i.e., the mind) never changes.^[26]

Classification of teachings

As with many Buddhist scholars of the day, doctrinal classification (p’an chiao) was an integral part of Zongmi's work.^[27] Zongmi provided a schematic analysis of various teachings and practices that attempts to show that all the various Buddhist canonical teachings and all the various Chan teachings do not conflict.^[16] He organized all teachings into a hierarchical schema that integrates and validates all traditions and teachings, seeing each lower category as partially true. According to Gregory, "the logic by which such a synthetic approach worked was dialectical. Each teaching overcame the particular shortcoming of the one that preceded it, and the highest teaching was accorded that vaunted position precisely because it succeeded in sublating all of the other teachings within itself."^[16]

Zongmi's schema arranged the Buddhist teachings into five categories:

1. The teaching of men and gods (人天教), including other religions like Confucianism and Daoism;
2. The teachings of the Hinayana (Lesser Vehicle, non-Mahayana Buddhism) (小乘教);
3. The teaching of the Mahayana on phenomenal appearances (大乘法相教);
4. The teaching of the Mahayana on eliminating appearances (大乘破相教);
5. The teaching of the Ekayāna that reveals the nature (一乘顯性教), the teaching of intrinsic enlightenment found in the Awakening of Faith and the Sutra of Perfect Enlightenment.^[28]

In Zongmi's teaching, the "nature" of each person is identical with Buddha-nature, which is emphasised in Chan. He stated, "To designate it, initially there is only one true spiritual nature, that is not born, does not die, does not increase, does not decrease, does not become, and does not change."^[29] In giving this teaching the highest position, Zongmi altered the classification of Fazang, who regarded the Hua-yen teachings to be the supreme teachings^[30] and established the common denominator of Chan and Huayen teachings within the "One Vehicle" (Ekayāna).

Hongzhou and Baotang schools

Zongmi was critical of certain Chan sects that seemed to ignore the moral order of traditional Buddhism and Confucianism. For example, while he saw the Northern line as believing "everything as altogether false", Zongmi claimed the Hung-chou tradition, derived from Mazu Daoyi (709–788), believed "everything as altogether true".^[36]

According to Zongmi, the Hung-chou school teaching led to a radical nondualism that believed that all actions, good or bad, as expressing essential Buddha-nature, denying the need for spiritual cultivation and moral discipline. Zongmi described their teaching as "entrusting oneself to act freely according to the nature of one's feelings".^[6] For Zongmi, this was a dangerously antinomian view as it eliminated all moral distinctions and validated any actions as expressions of the essence of Buddha-nature.^[6]

Zongmi also criticized the Baotang school on similar lines. According to Zongmi, this school had misinterpreted Shenhui's teaching on "no-thought" as entailing "the rejection of all forms of traditional Buddhist ethical practice and ritual observance."^[6]

While Zongmi acknowledged that the essence of Buddha-nature and its functioning in the day-to-day reality are but difference aspects of the same reality, he insisted that there is a difference. To avoid the dualism he saw in the Northern Line and the radical nondualism and antinomianism of the Hung-chou school, Zongmi's paradigm preserved "an ethically critical duality within a larger ontological unity",^[37] an ontology which he claimed was lacking in Hung-chou Chan.

Northern Chan

Zongmi's critique of Northern Chan was based on its practice of removing impurities of the mind to reach enlightenment. Zongmi criticized this on the basis that the Northern school was under the misconception that impurities were "real" as opposed to "empty" (i.e., lack any independent reality of their own) and therefore this was a dualistic teaching. Zongmi, on the other hand, saw impurities of the mind as intrinsically "empty" and naturally removable by the intrinsically pure nature of the mind. This understanding of Zongmi came from the Awakening of Faith in the Mahayana scripture which espoused the "Buddha-nature doctrine" of the intrinsically enlightened nature possessed by all beings.

Oxhead school

His criticism of another prominent Chan lineage of the time, the Oxhead school, was also based on the tathāgatagarbha doctrine but in this case Zongmi saw their teaching as a one-sided understanding of emptiness. He claimed that the Oxhead School taught "no mind" (i.e., the emptiness of mind) but did not recognize the functioning of the mind, assuming that the intrinsically enlightened nature is likewise "empty" and "that there is nothing to be cognized". Zongmi went on to say, "we know that this teaching merely destroys our attachment to feelings but does not yet reveal the nature that is true and luminous".^[38]

Work on the Sutra of Perfect Enlightenment

Zongmi's first major work was his commentary and sub-commentary on Sūtra of Perfect Enlightenment, completed in 823–824. The sub-commentary contains extensive data on the teachings, the ideas and practices on the seven houses of Chan. These data are derived from personal experience and observations.^[12] These observations provide excellent sources on Tang dynasty Chan for modern studies. The work focuses on the theory of Buddhist practice and discusses the details of practice as well.

Zongmi also wrote a major work in eighteen fascicles called A Manual of Procedures for the Cultivation and Realization of Ritual Practice according to the Scripture of Perfect Enlightenment. In this work, Zongmi discusses the theoretical basis of Buddhist practice as well as the specific details of Buddhist practice. According to Gregory, the work is influenced by the writings of Zhiyi and explains a "complex program of ritual and meditation practice in terms of the Scripture of Perfect Enlightenment."^[39]

Chart of Chan Succession

The Chart of the Master-Disciple Succession of the Chan Gate That Has Transmitted the Mind-Ground in China (Chung-hua ch’uan-hsin-ti ch’an-men shih-tzu ch’eng-his t’u), was written at the request of P’ei Hsiu sometime between 830 and 833. The work clarifies the major Ch’an traditions of the Tang era. It contains detailed critiques of the Northern School, the Ox-head School and the two branches of Southern Chan, the Hung-chou and his own Ho-tse (Heze) lines.^[41]

The Chan Preface

The Prolegomenon to the Collection of Expressions of the Chan Source, also known as the Chan Preface, was written around 833. It provides a theoretical basis for Zongmi's vision of the correlation between Chan and the Buddhist scriptures. It gives accounts of the several lineages extant at the time, many of which had died out by the time of the Song dynasty (960–1279).^[42] In this preface, Zongmi says that he had assembled the contemporary Chan practices and teachings into ten categories. Unfortunately, the collection itself is lost, and only the preface exists.

On the Original Nature of Man

Zongmi's Inquiry into the Origin of Humanity, (or On the Original Nature of Man, or The Debate on an Original Person) (原人論 Yüanren lun)^[43] was written sometime between 828 and 835. This essay became one of his best-known works.

It surveys the current major Buddhist teachings of the day, as well as Confucian and Taoist teachings. The text aims to show not only how Buddhism is superior to the native Chinese philosophies, but also to present a hierarchy of the profundity of the Buddhist schools. Zongmi criticizes Confucianism for not having an adequate moral system or explanation of causation. He holds up the Buddhist view of karma as the superior system of moral responsibility.

De Bary writes,

Here Tsung-mi's own spiritual development and his consideration of alternative philosophies are clearly reflected, as is his awareness of the need to defend his new faith against critics upholding Chinese tradition against Buddhism It has been said that Tsung-mi wrote this treatise as an answer to the famous essays On the original Nature of Man (Yuan jen) and On the Tao (Yuan tao) by his contemporary Han Yu (768–824), leader of the Confucian resurgence against Buddhism.^[44]

However, his goal was not to wholly denigrate or invalidate the Chinese philosophies, but to integrate them into Buddhist teachings to reach a greater understanding of how the human condition came into being.^[22]

The writing style is simple and straightforward, and the content not overly technical, making the work accessible to non-Buddhist intellectuals of the day.^{[lower-alpha 4]}
