How was the 14th Dalai Lama educated at the Potala Palace?

The 14th Dalai Lama, born Lhamo Thondup, began his formal education after moving into the Potala Palace following his enthronement in 1940.1

Separated from his family, he underwent a rigorous monastic education under the guidance of distinguished scholars. While his primary focus was this traditional religious training, he also gained insights into the outside world through newsreels, magazines, and his interactions with the Austrian mountaineer Heinrich Harrer, who spent seven years in Tibet. During this period, the actual administration of state affairs remained under the authority of a regent.1
