聊齋誌異 卷三 西僧 西僧自西域來，一赴五臺，一卓錫泰山。其服色言貌，俱與中國殊異。 自言：「歷火燄山，山重重，氣熏騰若爐灶。凡行必於雨後，心凝目注，輕蹟步履之；悞蹴山石，則飛燄騰灼焉。又經流沙河，河中有水晶山，峭壁插天際，四面瑩澈，似無所隔。又有隘，可容單車；二龍交角對口，把守之。過者先拜龍；龍許過，則口角自開。龍色白，鱗鬣皆如晶然。」 僧言：「途中歷十八寒暑矣。離西土者十有二人，至中國僅存其二。西土傳中國名山四：一泰山，一華山，一五臺，一落伽也。相傳山上遍地皆黃金，觀音、文殊猶生。能至其處，則身便是佛，長生不死。」 聽其所言狀，亦猶世人之慕西土也。倘有西游人，與東渡者中途相值，各述所有，當必相視失笑，兩免跋涉矣。
