Pal K'or tsan, the second western king, after a reign of thirteen years, died leaving two sons, Thi Tashi Tsegpa-pal and Thi Kyida Nyimagon.
Tashi Tsegpa also had three sons - Palde, Hodde and Kyide.
These two leaders were then known as the Dalai Lama and the Pantshen Lama, and were the abbots of the great monasteries at Gedun Dubpa, near Lhasa, and at Tashi Lunpo, in Farther Tibet, respectively.
