Tibetan Buddhism began in the Songtsen Gampo era in the 7th century. With the arrival of Princess Bhrikuti of Nepal and Princess Wencheng of the Tang Dynasty, Buddhist gods, an important symbol of Buddhism, were introduced to Tibet. From a certain perspective, the 8-year-old Shakyamuni Buddha statue brought by Princess Bhrikuti and the 12-year-old Shakyamuni statue brought by Princess Wencheng almost became the beginning of the history of Tibetan Buddhism. After more than 1,300 years of historical evolution and development, an intense ethnic style and local characteristic have been formed.
According to Tibetan Buddhism, the female buddha goddess is the source of all Buddhas. It mainly includes Palden Lhamo, Dakini, Usnisavijaya, Ushnisha Sitatapatra, and so on.
