Yaoshan Weiyan (Chinese: 藥山惟儼; Japanese: Yakusan Igen; Korean: Yaksan Yuǒm; Vietnamese: Dược Sơn Duy Nghiễm) was a Zen Buddhist monk who lived during the Tang dynasty. As with most monks of the Tang Dynasty, there are conflicting lines of evidence concerning Yaoshan's life. The earliest biographical information comes from Tang Shen, who wrote Yaoshan's epitaph in 834, seen years after his death. While he is traditionally regarded as a student of Shitou Xiqian, Tang Shen's inscription mentions that he stayed with Mazu Daoyi for nearly 20 years. It also mentions Shitou as his teacher, however. Some scholars consider the epitaph to be a later forgery, although many elements of it agree with other sources. A story dating to the middle of the eleventh century relates an encounter between Yaoshan and Shitou in which Yaoshan failed to awaken, but a later visit to Mazu results in his enlightenment. This is almost certainly a fanciful jibe at Shitou and praise for Mazu, however.
