This book records a Buddhist text given to the Qianlong emperor (r. 1736–95) by a Panchen Lama from Tibet. The calligraphy was written by the court official Liang Guozhi (1723–1774) then engraved into the jade pages and painted gold. A number of jade books were made during the reign of Qianlong, whose penchant for this stone and partiality to all sorts of extravagances is well recorded.
