Sidkeong Tulku Namgyal
He was the eldest son and heir of Maharaja Sri Panch Sir Thutob Namgyal, and was educated at St. Paul's School, Darjeeling and at Pembroke College, Oxford. A polyglot, he was learned in Chinese, English, Hindi, Lepcha, Nepali and Tibetan.
After his education in Oxford, he returned to Sikkim where he was closely associated with the administration of the country. He worked to dissolved the greed that occurs in vested interests and tried to unify Buddhists by renovating monasteries and their roles.
When Alexandra David-Néel was invited to the royal monastery of Sikkim, she met Sidkeong Tulku Namgyal, at that time Maharaj Kumar (crown prince). She became Sidkeong's "confidante and spiritual sister", perhaps her lover.
