In the seventeenth century, during the reign of the Fifth Dalai Lama, the protector deity Pehar and his oracle at Nechung Monastery were state-sanctioned by the nascent Tibetan government, becoming the head of an expansive pantheon of worldly deities assigned to protect the newly unified country. The governments of later Dalai Lamas expanded the deity's influence, as well as their own, by establishing Pehar at monasteries and temples around Lhasa and across Tibet. Pehar's cult at Nechung Monastery came to embody the Dalai Lama's administrative control in a mutual relationship of protection and prestige, the effects of which continue to reverberate within Tibet and among the Tibetan exile community today. The friendship between these two immortals has spanned nearly five hundred years across the Tibetan plateau and beyond.
