A second and larger expedition sent by the Kangxi Emperor, together with Tibetan forces under Polhane (also spelled Pho-lha-nas) of Tsang and Gangchenney (also spelled Kang-chen-nas), the governor of Western Tibet, expelled the Dzungars from Tibet in 1720. They brought Kelzang Gyatso with them from Kumbum to Lhasa and he was enthroned as the seventh Dalai Lama in the Potala in 1721, or in November 1720. He took the novice vows of monk-hood from the 5th Panchen Lama Lobsang Yeshi, who gave him the name Kelsang Gyatso. He took the Gelong vows (full ordination) from Lobsang Yeshi in 1726. He received teachings from the tutor of Lobsang Yeshi, the Abbot of Gyumey Monastery and also from the Abbot of Shalu Monastery, Ngawang Yonten on all the major Buddhist philosophical treatises and became a master in both sutra and tantra. He was a great scholar and wrote many books, especially on the tantra. He was also a noted poet who, unlike the 6th Dalai Lama, Tsangyang Gyatso, dwelt mainly on spiritual themes.
