Introduction to the Shelton Festival
Shelton Festival, meaning "yogurt feast", was interpreted as a festival for drinking yogurt. Later, it gradually evolved into a Tibetan opera performance, also known as the "Tibetan Opera Festival". And because there are grand and enthusiastic Tibetan opera performances and grand-scale Buddha-drying ceremonies during the Shelton Festival, some people also call it "Tibetan Opera Festival" and "Sunning Buddha Festival".
According to the rules of the Gelug school (Yellow Sect) of Tibetan Buddhism, the prohibition period is from June 15 to July 30 in the Tibetan calendar every year, and lamas of large and small temples are not allowed to go out, so as not to trample on small insects, and can not go down the mountain until the ban is lifted on July 30. When the lama descends the mountain, farmers and herders take out yogurt to offer, forming the Shelton Festival.
The traditional Shelton Festival begins with the exhibition of the Buddha. The main content is to perform Tibetan opera and tibetan opera, mass garden tour, and there are also wonderful yak racing and equestrian performances.
Origin of the Shelton Festival
The Festival of Shelton originated in the middle of the 11th century AD, when the Festival was a purely religious practice. According to folklore, there are more than three hundred precepts in Buddhism, and the most taboo is to kill people. Due to the warming of the weather in summer, the growth of grass and trees, the sting of hundreds of insects, and the recovery of all things, monks will inevitably trample on life when they go out to move, which violates the precept of "not killing". Therefore, the Gelug precepts stipulate that between April and June of the Tibetan calendar, lamas can only stay in monasteries and practice quietly behind closed doors, called "Yale", which means "summer dwelling", and cannot be banned until the end of June. On the day of the lifting of the ban, the monks went out of the monastery one after another, and the secular people prepared yogurt to treat the monks, held a picnic feast for them, and performed Tibetan opera at the celebration. This is where the Shelton Festival comes from.
