On his way to meet Altan Khan near Qinghai Lake, the 3rd Dalai Lama stopped at the isolated retreat by the holy tree marking the spot where Tsongkhapa had been born. He requested Tsöndrü Gyeltsen to construct a larger monastery at this site and appointed him as the head lama. The monastery was built completely in 1583 and a fence was erected around the "Tree of Great Merit". An annual Monlam Prayer Festival () was inaugurated, like the one held in Lhasa. The new monastery was called Kumbum Jampa Ling. "Kumbum" means "100,000 enlightening bodies of the Buddha". It is named after the 100,000 images of Siṃhanāda which appear on the leaves of the holy sandalwood tree. "Jampa ling" means "Maitreya Cloister." This refers to the Maitreya temple built by Tsöndrü Gyeltsen to the right of the precious tree.
