Il eut une conversation avec Laurence Waddell au cours de laquelle Lobsang Gyaltsen, sachant que Waddell écrit un ouvrage sur le bouddhisme lui demande s'il est bouddhiste. Waddell lui répond qu'il ne l'est pas, mais qu'il est de religion chrétienne, où il voit des similitudes. Lobsang Gyaltsen pense que les Britanniques n'ont pas de religion, étant donné le nombre de Tibétains qu'ils ont tué.

There he received another letter from the Tibetan government urging his return; but he replied that the former Kalon, Paljor Dorje Shatra, should be appointed Lonchen (Prime Minister) to look after the administration, together with the Regent. Shatra declined the offer unless his two former colleagues, Sholkhang and Changkhyim, should also be reinstated. Finally, all three of them were made Lonchen, with authority over the Kashag. Although they took over the actual responsibilities of the government, they acknowledged the seniority of the Regent and gave the Kashag ministers precedence in ceremonial matters. »
