When Lhamo Thondup was barely three years old, a search party that had been sent out by the Tibetan government to find the new incarnation of the Dalai Lama arrived at Kumbum monastery. It had been led there by a number of signs. One of these concerned the embalmed body of his predecessor, Thupten Gyatso, the Thirteenth Dalai Lama, who had died aged fifty-seven in 1933. During its period of sitting in state, the head was discovered to have turned from facing south to northeast. Shortly after that the Regent, himself a senior lama had a vision. Looking into the waters of the sacred lake, Lhamo Lhatso, in southern Tibet, he clearly saw the Tibetan letters Ah, Ka and Ma float into view. These were followed by the image of a three-storied monastery with a turquoise and gold roof and a path running from it to a hill. Finally, he saw a small house with strangely shaped guttering. He was sure that the letter Ah referred to Amdo, the northeastern province, so it was there that the search party was sent.

By the time they reached Kumbum, the members of the search party felt that they were on the right track. It seemed likely that if the letter Ah referred to Amdo, then Ka must indicate the monastery at Kumbum, which was indeed three-storeyed and turquoise-roofed. They now only needed to locate a hill and a house with peculiar guttering. So they began to search the neighbouring villages. When they saw the gnarled branches of juniper wood on the roof of the Dalai Lama's parents' house, they were certain that the new Dalai Lama would not be far away. Nevertheless, rather than reveal the purpose of their visit, the group asked only to stay the night. The leader of the party, Kewtsang Rinpoche, then pretended to be a servant and spent much of the evening observing and playing with the youngest child in the house.

The child recognised him and called out 'Sera lama, Sera lama’. Sera was Kewtsang Rinpoche's monastery. The next day they left only to return a few days later as a formal deputation. This time they brought with them a number of things that had belonged to the Thirteenth Dalai Lama, together with several similar items that did not. In every case, the infant correctly identified those belonging to the Thirteenth Dalai Lama saying, It’s mine. It’s mine. This more or less convinced the search party that they had found the new incarnation. It was not long before the boy from Taktser was acknowledged to be the new Dalai Lama.

The boy, Lhamo Thondup was first taken to Kumbum monastery. "There now began a somewhat unhappy period of my life," The Dalai Lama was to write later, reflecting on his separation from his parents and the unfamiliar surroundings. In the summer of 1939, Lhamo Thondup made the journey to the capital, Lhasa, in a large party consisting his parents, his brother Lobsang Samten, members of the search party and other pilgrims.

The journey to Lhasa took three months. Upon their arrival, Lhamo Thondup’s party was received by a group of senior government officials and escorted to Doeguthang plain, two miles outside the gates of the capital. The next day, a ceremony was held in which Lhamo Thondup was conferred the spiritual leadership of his people. Following this, he was taken off with Lobsang Samten to the Norbulingka, the summer palace of His Holiness, which lay just to the west of Lhasa.

During the winter of 1940, Lhamo Thondupwas taken to the Potala Palace, where he was officially installed as spiritual leader of Tibet. Soon after, the newly-recognised Dalai Lama was taken to Jokhang temple where His Holiness was inducted as a novice monk in a ceremony known as taphue, or ‘cutting of the hair’. From then on, he was to be shaven-headed and attired in maroon monk's robes.
