The Sakya lineage traces its roots to three celestial siblings from the Clear Light heaven in Form Realm. The three, who were emanations of Manjushri, descended to Earth at a location in western Tibet, well known as the Clear Light Celestial Lineage. These brothers up to their descendant Yapang Kye are collectively known as the « Thirteen Divine Beings ».
Later, a son was born in the midst of conflict between this lineage and the rakshas, and his lineage became known as the Unsullied Lineage of Khön (conflict).
Luwang Sungwa, a descendant from the Khön lineage, received teachings such as Vajrakilaya from Guru Padmasambhava and was among the first seven Tibetans to be ordained as Buddhist monks by Shantirakshita at Samye monastery.
