Тан дәуіріндегі Хуанбо Сиюнь: Чань шеберінің өмірі мен ізденістері

Huángbò Xīyùn (, Ōbaku Kiun) (died 850) was an influential master of Zen Buddhism during the Tang dynasty. Huángbò was a disciple of Baizhang Huaihai (720–814), and the teacher of Linji Yixuan (died 866) (Wade–Giles: Lin chi I hsüan; Japanese: Rinzai Gigen).

Huángbò began his monastic life on Mt. Huangbo in Fujian province, receiving the Buddhist name Xiyun (Hsi yun). As was the custom of the times, he traveled around seeking instructions from various Chan masters. He visited Mt. Tiantai and sought teachings from the National Teacher Nanyang Huizhong (Wade–Giles: Nan yang Hui chung; Japanese: Nan’yō Echū). At some point he may also have studied under Nanquan Puyuan (748–835) (Wade–Giles: Nan ch’üan P’u yüan; Japanese: Nansen Fugan), a student of Mazu Daoyi (Wade–Giles: Ma tsu Tao i; Japanese: Baso Dōitsu) (709–788)

However, Huángbò's main teacher was Baizhang Huaihai (Wade–Giles: Pai chang Huai hai; Japanese: Hyakujo Ekai), another Mazu student, and it was from Baizhang that Huángbò received Dharma transmission. According to Yuanwu Keqin's commentary in The Blue Cliff Record, when Huángbò first met Baizhang, Baizhang exclaimed, “Magnificent! Imposing! Where have you come from?” Huángbò replied, “Magnificent and imposing, I’ve come from the mountains.”

In 842, a prominent government official in Kiangsi province, Pei Xiu (Wade–Giles: P’ei Hsiu) (787 or 797–860), invited Huángbò to take up residence at Lung hsing Monastery. Pei was an ardent student of Chan and received teachings from Huángbò, eventually building a monastery for Huángbò around 846, which the master named Huang po after the mountain where he had been a novice monk.

Before Huángbò died, he named thirteen successors, the most prominent of which was Linji Yixuan. He was given the posthumous title (probably under the urging of Pei Xiu who became chief minister of the central government in 853) of “Chan Master Without Limits” (Tuan Chi Ch’an Shih). John Blofeld says he died on Mount Huangbo during the T'ai Chung reign of the Tang dynasty, or between 847 and 859. Blofeld says his memorial pagoda is "The Tower of Spacious Karma" and that it was Emperor Hsüan Tsung who gave him the title "The Zen Master Who Destroys All Limitations".
