The core stories of these theatrical plays are drawn mostly from ancient Indian Buddhist folk tales, lives of important people and historical events from Tibetan civilization.
Today, the same opening rituals are enacted prior to the commencement of every performance, authentic costumes are worn, singing, dance and musical tradition are strictly adhered to.
According to some oral narratives, the costumes and mask of Hunter or Fisherman (Tibetan: Ngonpa) were designed by the fifth Dalai Lama, based on his personal dream.
"[4] It is popularly believed that the tradition of performing Ache Lhamo or Tibetan Opera was started by 14th-century mystic Thang Tong Gyalpo, who was born in the family of a peasant in the Shigatse county of Tibet in 1361.
Thus, during the construction of the bridge at Chowo Ri, from his labor team he picked seven sisters from Lhoka county of Tibet and taught them some dances and songs.
They made up the chorus and adorned them with beautiful costumes; they traveled around towns and villages performing dances to raise resources.
During the opening ritual dance, every lhamo or opera group installs his statue in the middle of the stage and pays homage to him.
