"The service is to pray for world peace, the nation's prosperity and and people's health and safety," said Khenpo Ngangor, an abbot of the monastery.
"We hope the natural disasters threatening people in the world will end, and that all families live happily and stay healthy," the abbot said.
The 2,100-year-old Jyegu Monastery is the largest and most influential temple of the Sakya school of Tibetan Buddhism. It is located in the Tibetan Autonomous Prefecture of Yushu.
The monastery has held the mass prayer service for the past 14 years around Oct. 15 on the Tibetan calendar.
