Hongren (弘忍, महाक्षान्ति - Mahākṣānti; ཧོང་རེན། hong ren Hongren, universally revered across China, Japan, Korea, Vietnam, and East Asia as Daman Chanshi - 大滿禪師, Chan Master of Great Fullness, and in Japan as Daiman Kōnin), acclaimed throughout East Asian Buddhist history as the foremost disciple of Daoxin (580–651) and the Fifth Patriarch of Chan (Seon / Zen) Buddhism, stands as the revered 7th century master of the East Mountain Teaching (Dongshan Famen) who nurtured the great flowering of classical Chan and transmitted the patriarchal lineage to Huineng (638–713). With his year of birth in 601 (or 602) and his year of death in 674 (or 675), Hongren was born into the Zhou family in Huangmei in Hubei province, China, growing up in humble circumstances under the care of his widowed mother. Displaying extraordinary contemplative stillness, filial piety, and acute awareness of anicca and dukkha from early childhood—possessing auspicious physical features and never weeping or engaging in childish quarrels—young Hongren encountered the Fourth Patriarch Daoxin on a country road in Huangmei at the age of seven; deeply moved by the child's luminous bearing, Daoxin secured his mother's joyful permission, guided him in fearless renunciation and formal refuge in the Buddha, the Dharma, and the Sangha, and later conferred upon him full monastic ordination in the Dharmaguptaka Vinaya Pitaka lineage while upholding strict monastic precepts and ethical conduct.
Training under Daoxin for over thirty years at Shuangfeng Mountain (Twin Peaks Mountain), Hongren dedicated his days to humble, strenuous manual labor—chopping firewood, carrying water, tilling the monastery gardens, and repairing temple walls—while dedicating his nights to uninterrupted seated meditation, mindfulness, and single-pointed concentration. Recognizing Hongren's profound, silent awakening and unshakeable spiritual maturity, Daoxin transmitted to him the patriarchal robe and begging bowl of Bodhidharma, the direct mind-to-mind seal of Chan, and the four-fascicle Gunabhadra translation of the Lankavatara Sutra (लङ्कावतारसूत्र - Laṅkāvatārasūtra, Taisho Number 670 in the Chinese Tripitaka and Toh Number 107 in the Tibetan Tripitaka) before passing into parinirvana in 651.
Following Daoxin's passing, Hongren relocated his growing monastic community eastward across the valley to Pingmao Mountain (East Mountain, Dongshan) in Huangmei, founding Dongshan Monastery (Five Ancestors Monastery). Over the next two decades, Hongren transformed Dongshan Monastery into the most vibrant spiritual center in Tang dynasty China, attracting over seven hundred dedicated monastics and lay seekers from every corner of the empire—including Yuquan Shenxiu (606–706), Songyue Hui'an (582–709), Zizhou Zhishen (609–702), Lao'an, and the illiterate southern woodcutter Huineng—and solidifying the celebrated East Mountain Teaching (Dongshan Famen, 東山法門).
Around 661, when Huineng arrived from Guangdong province and declared that innate Buddha-nature (tathagatagarbha) has neither north nor south, Hongren immediately recognized the future Sixth Patriarch, assigned him to pound rice in the threshing room for eight months to protect him from monastic rivalry, and convened the famous verse-writing assembly to test his disciples' realization. After Yuquan Shenxiu inscribed his verse comparing the mind to a bright mirror stand requiring constant wiping and Huineng dictated his transcendent reply proclaiming that Bodhi has no tree and originally not a single thing exists, Hongren secretly summoned Huineng to his quarters at midnight, expounded the Vajracchedika Prajnaparamita Sutra (Diamond Sutra, Taisho Number 235 and Toh Number 16 in the Tibetan Tripitaka), confirmed his complete non-dual awakening, entrusted him with the patriarchal robe and bowl, and escorted him southward across the Yangtze River to safety.
Literarily, Hongren's essential contemplative instructions were preserved in the Chinese Tripitaka in the Zuishangcheng Lun (最上乘論, Treatise on the Supreme Vehicle, also titled Xiuxin Yaolun, 修心要論, Treatise on the Essentials of Cultivating the Mind, Taisho Number 2011), as well as in early Chan histories including Jingjue's Lengqie Shizi Ji (Taisho Number 2837) and the Jingde Chuandeng Lu (Taisho Number 2076). Synthesizing the direct mind-pointing of Bodhidharma with the Vajracchedika Prajnaparamita Sutra and the Wenshu Shuo Bore Jing (Taisho Number 232 and Toh Number 24), the Treatise on the Essentials of Cultivating the Mind became a foundational manual for both early Chan practitioners and the later Tibetan Chan transmissions of Moheyan at Samye.
Philosophically and contemplatively, Hongren taught the luminous practice of “Guarding the True Mind” (Shou Benxin, 守本心), explaining that the primordially pure, radiant Buddha-nature (tathagatagarbha) of all sentient beings is eternally complete like the bright sun hidden behind passing clouds of conceptual delusion. Harmonizing this direct insight with Nagarjuna's Madhyamaka dialectics regarding emptiness (शून्यता - śūnyatā; སྟོང་པ་ཉིད། stong pa nyid Tongpanyid) and dependent origination, Asanga's Yogacara phenomenology, and Maitreya's Uttaratantra Shastra (Toh Number 4024 and Taisho Number 1611), Hongren instructed disciples to sit upright in balanced posture, settle their awareness effortlessly within their own fundamental mind, and let clinging to the five aggregates, anatta, emptiness of self, karma, and rebirth across samsara and nirvana dissolve naturally into clear right view and non-attachment.
Throughout his teaching career on East Mountain—declining repeated imperial invitations from Emperor Gaozong of Tang to visit Chang'an in order to remain devoted to his mountain community—Hongren modeled humble egalitarian labor alongside his disciples while anchoring monastic conduct in Shakyamuni Buddha's foundational teachings on the Four Noble Truths, the Noble Eightfold Path, generosity, merit, loving-kindness, compassion, equanimity, skillful means, and universal bodhicitta to uproot the three poisons of greed, hatred, and delusion across the six realms.
Passing into final parinirvana at Dongshan Monastery on East Mountain in 674 (or 675) at the age of seventy-three seated upright in the lotus posture after announcing that his work was finished and directing his disciples to build his memorial stupa, Hongren was posthumously honored by Emperor Daizong of Tang with the imperial title Daman Chanshi (Chan Master of Great Fullness). Revered as the great pivot of Chinese Chan whose disciples carried the lineage into both the Northern School of Yuquan Shenxiu and the Southern School of Huineng, Hongren stands forever alongside Bodhidharma, Dazu Huike, Sengcan, Daoxin, and Nagarjuna as a supreme guardian of the Middle Way.
