In the view of "biographical literature," Biographies of Eminent Monks is "full of humanity description" and is considered as a climax of Chinese biography; for the non-Buddhists, however, the most striking characteristic of Eminent Monks should be the miraculous ability of the biographees. To extend the current studies, this paper attempts to re-evaluate the features of Eminent Monks by investigating Hui Jiao's writing motivation, the mystic plots, the criteria of selection, the personality of biographees, the secondary characters, space and background, etc. This research suggests that Eminent Monks uses a dual "holy rhetoric"- superhuman / human and holy / mundane - to impress the readers and propagate Buddhism.
