Golden Light Sutra

The Golden Light Sutra or  (सुवर्णप्रभासोत्तमसूत्रेन्द्रराजः) 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 has been carried down through tradition into modern times and is customarily performed in Chinese Buddhist temples on the 9th day of the 1st month of the Chinese calendar.

The sutra also gained esteem as a sutra for protecting the country in China, Korea and Japan, and often was read publicly to ward off threats. For example, its first reading in Japan was as a court ceremony during around 660 AD, when the Tang dynasty of China and Silla of Korea defeated the state of Baekje of Korea and were threatening Japan. In 741 Emperor Shōmu of Japan founded provincial monasteries for monks (国分寺) and nuns (国分尼寺) in each province. The official name of the monasteries was the Temple for Protection of the State by the Four Heavenly Kings Golden Light Sutra. The 20 monks who lived there recited the Sovereign Kings Golden Light Sutra on a fixed schedule to protect the country. As Buddhism evolved in Japan, the practice gradually fell out of use, and is no longer continued today.

Japanese
One of the earliest Japanese annotations was an 8th-century kunten translation of the Yijing Chinese translation housed in Saidaiji Temple.

In 1933, Izumi published the first complete Japanese translation directly from Sanskrit, followed by another translation by Ama a year later.

Western languages
In 1958, Nobel published a German translation, based on Yijing's Chinese text. In 1970, Emmerick produced an English translation of the short, condensed Sanskrit version of the Sutra of Golden Light into English.

In Tibetan, there are three versions of the Sutra: the 21, 29, and 31 chapter versions. The 29 Chapter Version was probably the most popular in Tibet and Tibetan Buddhist regions.

In 2007, the Foundation for the Preservation of the Mahayana Tradition, Lama Zopa Rinpoche's Buddhist organization, produced a translation of the 21 chapter version of the Sutra, the most abbreviated and condensed version.
