The Suvarņaprabhāsa-sūtra (or, Golden Light Sutra) is one that highlights a discourse by Shakyamuni in Rajagriha, India. It is taught that those who embrace the scripture will obtain the protection of the four heavenly kings and other benevolent deities, and that, if a ruler takes faith in the correct teaching, these deities will protect his country. It was introduced to China in early fifth century, and was immediately received by the Han Chinese as well as the noblemen and common souls of many neighboring states. There were five Chinese translations, and to date the ten-chüan A Vision of the Suvarņa-prabhāsa Sūtra (also known as Sovereign Kings of the Golden Light Sutra) rendered by Master I-ching (635-713) in 703, known for its comprehensiveness, accuracy, and textual fluidity, has been the most popular version. I-ching was a priest of T'ang China who traveled via marine routes to India to study Buddhism. He stayed there for twenty-five years and visited more than thirty Buddhist sites. After he returned to China with four hundred Sanskrit scriptures, I-ching devoted himself to translating them. He translated fifty-six titles of Buddhist texts in two hundred and thirty chüan, and was acknowledged as one of the four greatest translators of Buddhist scriptures. The version on view is one rendered by Chao Meng-fu, a scholar, painter, and calligrapher of the Yüan dynasty. Each volume features one chüan, and the large-sized characters are examples of fine calligraphic work.
