高僧傳 9.41

9.41

單道開，姓孟，燉煌人。少懷栖隱，誦經四十餘萬言。絕穀餌栢實。栢實難得，復服松脂，後服細石子。一吞數枚，數日一服，或時多少噉薑椒，如此七年。後不畏寒暑，冬溫夏涼，晝夜不臥。與同學十人共契服食，十年之外，或死或退，唯開全志。阜陵太守遣馬迎開，開辭能步行，三百里路一日早至。山樹神或現異形試之，初無懼色。以石虎建武十二年從西平來，一日行七百里。至南安，度一童子為沙彌，年十四，稟受教法，行能及開。

Shan Daokai, surnamed Meng, was a native of Dunhuang. From his youth he cherished seclusion, and chanted sūtras amounting to more than four hundred thousand words. He abstained from grains and fed on cypress seeds. When cypress seeds were difficult to obtain, he also ingested pine resin, and later ingested fine gravel. He swallowed several stones at a time, once every few days, occasionally eating some ginger or pepper; he did this for seven years. Thereafter he was not afraid of cold or heat, feeling warm in winter and cool in summer, and did not lie down day or night. He made a pact with ten fellow students to ingest these foods; after ten years, some died and some gave up, and only Daokai maintained his resolve intact. The grand administrator of Fuling sent horses to welcome Daokai, but Daokai declined, saying he could walk on foot, and arrived early in a single day over a journey of three hundred li. Spirits of the mountains and trees sometimes manifested strange forms to test him, but he showed no fear at all. In the twelfth year of the Jianwu era of Shi Hu, he came from Xiping, traveling seven hundred li in a single day. When he reached Nan'an, he ordained a boy as a novice monk, aged fourteen, who received the teachings and whose practice and ability matched Daokai's.
