还有两卷白绢写成的书，题名叫《九天太上道经》，明生也不敢打开看那经文，只任洒扫之职，看守石室而已。
有两卷素书，题曰《九天太上道经》。明生亦不敢发视其文，唯供洒扫，守岩室而已。
There were also two volumes of books written on white silk, entitled "Nine Heavens Supreme Dao Sutra". Mingsheng did not dare to open the scriptures to read them, but only served the task of sweeping and cleaning and guarding the stone room.
