Highly revered by Chinese Buddhists, the Mahāratnakūţa-sūtra is considered one of the five greatest scriptures. Very much in the form of a monographic series, the work is a collection of forty-nine sutras introducing the doctrines of all major schools of Mahayana Buddhism, with discourses espousing the mean between two extremes and the idea of a realm of mind beyond substance or nothing. It was translated into Chinese by Bodhiruci (562-727) and collated by him with various previous translations in 713. The work on view is a handwritten edition in gold ink, produced in 1430 at the order of the Ming emperor Hsüan-tsung. The Mahāratnakūţa-sūtra is 120 volumes in size, with each volume featuring a chüan. Fine illustrations can be found in the beginning of the first volume and the end of the last.
