Dazu Huike (慧可, प्रज्ञाक्षमा - Prajñākṣamā; ཏ་ཙུ་ཧུའེ་ཁེ། ta tsu hu'e khe Tatsu Huekhe, universally revered across China, Japan, Korea, Vietnam, and East Asia as Erzu Huike - 二祖慧可 / Zhengzong Pujue Dashi - 正宗普覺大師, and in Japan as Taiso Eka), acclaimed throughout East Asian Buddhist history as the foremost disciple of Bodhidharma (d. 528) and the Second Patriarch of Chan (Seon / Zen) Buddhism, stands as the heroic 5th century and 6th century contemplative master who anchored the direct mind-to-mind transmission of awakening upon Chinese soil. With his year of birth in 487 and his year of death in 593, Dazu Huike was born into the Ji family in Hulao (modern Xingyang) in Henan province, China, originally named Ji Shenguang (Divine Light) after miraculous radiant illumination filled his parents' home on the night of his birth. Gifted with prodigious intellect, literary mastery, and spiritual sensitivity from early youth, he studied the Confucian classics and Daoist texts exhaustively before recognizing their inability to resolve the pervasive reality of anicca and dukkha, practicing fearless renunciation, taking formal refuge in the Buddha, the Dharma, and the Sangha, and receiving full monastic ordination at Yongming Monastery in Luoyang under Chan master Baojing in the Dharmaguptaka Vinaya Pitaka lineage while upholding strict monastic precepts and ethical conduct.
After eight years of intensive scriptural study and solitary meditation, mindfulness, and single-pointed concentration at Xiangshan Monastery near Longmen—where a visionary deity appeared in a vision instructing him to travel southward to Mount Song to receive the true seal of the Dharma—Dazu Huike journeyed to Shaolin Monastery around 520–526 to seek out the Indian master Bodhidharma, who was sitting in silent nine-year wall-gazing contemplation inside a mountain cave. Repeatedly ignored by Bodhidharma, Dazu Huike stood motionless outside the snowbound cave through a freezing winter night until the snow buried him up to his waist; when Bodhidharma finally turned and asked what he sought, Dazu Huike wept and declared his longing for the nectar of immortality to liberate all sentient beings, prompting Bodhidharma to test his resolve by remarking that the supreme vehicle cannot be attained with small virtue and faint heart.
According to classical Chan chronicles—and reflected in his monastic epithet Dazu (Great Ancestor / One-Armed)—Dazu Huike immediately drew a sharp blade and severed his own left arm, laying it before Bodhidharma as a testament of total, life-or-death sincerity for the Dharma. Moved by Dazu Huike's fearless right effort, Bodhidharma accepted him as his foremost disciple; when Dazu Huike pleaded that his mind was restless and begged Bodhidharma to pacify it, Bodhidharma commanded him to bring out his mind so he could pacify it, whereupon Dazu Huike searched within and confessed that when he looked for his mind it could never be found, prompting Bodhidharma to declare, “There, I have pacified your mind for you”—triggering an instantaneous explosion of non-dual awakening in Dazu Huike.
Serving Bodhidharma closely for six years at Shaolin Monastery, Dazu Huike received from his master the patriarchal robe and begging bowl, the direct mind-to-mind transmission 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), which Bodhidharma praised as the supreme scriptural mirror of the mind-ground in China. Following Bodhidharma's parinirvana around 528, Dazu Huike journeyed across northern China—visiting Luoyang and Yedu (capital of the Eastern Wei and Northern Qi dynasties)—teaching both monastics and laypeople with fearless non-attachment and equanimity.
During the devastating Northern Zhou persecution of Buddhism launched by Emperor Wu of Northern Zhou in 574–577, Dazu Huike fled southward into the mountains of Mount Sikong and Mount Wan in Anhui province to safeguard the scriptures and Buddha statues, living incognito among humble villagers and mountain recluses. There, around 535–550, Dazu Huike encountered a forty-year-old layman suffering from severe leprosy who humbly requested liberation from his karmic affliction; when the layman asked Dazu Huike to absolve his sins, Dazu Huike commanded him to bring out his sins so he could absolve them, and when the layman confessed that his sins could nowhere be found, Dazu Huike confirmed his sudden awakening, ordained him under the name Sengcan (d. 606), and transmitted to him the patriarchal lineage as the Third Patriarch of Chan.
Literarily, Dazu Huike's luminous teachings, letters, and dialogues were preserved in the Chinese Tripitaka in early Chan histories such as Daoxuan's Xu Gaoseng Zhuan (續高僧傳, Further Biographies of Eminent Monks, Taisho Number 2060), the Lengqie Shizi Ji (楞伽師資記, Records of the Masters and Disciples of the Lankavatara, Taisho Number 2837), and the Jingde Chuandeng Lu (景德傳燈錄, Taisho Number 2076), including his celebrated verse exchanges with lay scholar Xiang Jushi affirming that delusion and enlightenment are non-dual and that the true Buddha is never separate from one's own mind.
Philosophically and contemplatively, Dazu Huike embodied the seamless union of the Lankavatara Sutra's teachings on innate Buddha-nature (tathagatagarbha) and storehouse consciousness (alayavijnana) 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). Demonstrating that clinging to the five aggregates, anatta, emptiness of self, karma, and rebirth across samsara and nirvana dissolves instantaneously when the unfindable nature of mind is directly realized, he anchored his compassionate skillful means in Shakyamuni Buddha's foundational teachings on the Four Noble Truths, the Noble Eightfold Path, generosity, merit, loving-kindness, compassion, right view, and universal bodhicitta to uproot the three poisons of greed, hatred, and delusion across the six realms.
Passing into final parinirvana in 593 at the venerable age of one hundred and six in Cheng'an (Hebei province)—where, according to traditional Chan chronicles, envious sectarian rivals slandered him before local magistrates and had him executed, whereupon white milk rather than blood flowed from his neck as he accepted his final karmic debt with serene equanimity—Dazu Huike was posthumously honored by Emperor Dezong of Tang with the imperial title Dazu Chanshi (Great Ancestor Chan Master). Carried forward through Sengcan, Daoxin, Hongren, and Huineng across China, Korea, Japan, and Vietnam, Dazu Huike stands forever alongside Bodhidharma, Mazu Daoyi, Linji Yixuan, Nagarjuna, and Longchenpa as a supreme guardian of the Middle Way.
