The Golden Light Sutra or (), also known by the Old Uygur title Altun Yaruq, is a Buddhist text of the Mahayana branch of Buddhism. In Sanskrit, the full title is The Sovereign King of Sutras, the Sublime Golden Light. History The sutra was originally written in India in Sanskrit and was translated several times into Chinese by Dharmakṣema and others, and later translated into Tibetan and other languages. Johannes Nobel published Sanskrit and Tibetan editions of the text. The sutra is influential in East Asia. The name of the sutra derives from the chapter called "The Confession of the Golden Drum", where the bodhisattva Ruchiraketu dreams of a great drum that radiates a sublime golden light, symbolizing the dharma or teachings of Gautama Buddha. The Golden Light Sutra became one of the most important sutras in China and Japan because of its fundamental message, which teaches that the Four Heavenly Kings () protect the ruler who governs his country in the proper manner. The sutra also expounds the vows of the goddesses Sarasvatī (), Lakṣmī () and Dṛḍhā to protect any bhikṣu who will uphold and teach the sutra. Taken at face value, one might take the main theme of the sutra literally, which is the importance for leaders to be good examples for the kingdom. In Chapter Twelve, the sutra speaks in verse form about the disasters that befall a kingdom when its ruler does not uphold justice, and the benefits of kings who lead an exemplary life. In the Chapter on the Guardian Kings, the Four Guardian Kings have a dialogue with the Buddha, explaining in vivid detail all the benefits a kingdom will have if its ruler enshrines the essence of the sutra and offers daily praise. The sutra contains some elements of early tantra, in that in chapter two, the sutra describes four Buddhas who dwell in the four cardinal directions. These same four comprise later Buddhist mandalas in the same positions, such as the Womb Realm. During the Sui dynasty in China, the monk Zhiyi of the Tiantai tradition initiated a ritual ceremony known as "Gōngfó Zhāitiān" (供佛齋天) or just "Zhāitiān" (齋天), meaning "Puja of Offering to the Buddhas and the Devas", according to the rites prescribed in the Golden Light Sutra. During the ceremony, offerings are made to the Buddhas as well as the twenty-four devas as a sign of respect. This ceremony
