Palden Lhamo
It is said that Palden Lhamo, the female guardian spirit of the sacred lake, Lhamo La-tso, promised the First Dalai Lama in one of his visions "that she would protect the reincarnation lineage of the Dalai Lamas." Since the time of Gendun Gyatso, who formalised the system, monks have gone to the lake to seek guidance on choosing the next reincarnation through visions while meditating there. Gendun Gyatso is said to have been the first to discover the sacredness of Lake Lhamoi Latso.
