Nevertheless, Jamphel Gyatso was also said to possess all the signs of being the true incarnation of the Seventh. This was also claimed to have been confirmed by many portents clear to the Tibetans and so, in 1762, at the age of 5, he was duly enthroned as the Eighth Dalai Lama at the Potala Palace. At the age of 23 he was persuaded to assume the throne as ruler of Tibet with a Regent to assist him and after three years of this, when the Regent went to Beijing as ambassador in 1784, he continued to rule solo for a further four years. Feeling unsuited to worldly affairs, however, and unhappy in this role, he then retired from public office to concentrate on religious activities for his remaining 16 years until his death in 1804. He is also credited with the construction of the Norbulingka 'Summer Palace' started by his predecessor in Lhasa and with ordaining some ten thousand monks in his efforts to foster monasticism.
