Вообще буддизм к тому времени еще не укоренился среди монголов, даже официальное принятие буддизма Хубилаем случилось чуть позже. Т.е. сами монголы вряд ли могли привнести что-то ценное в смысле буддизма, но способствовать появлению там монахов буддийских могли. Вот нашел любопытный пассаж в книге Леонарда Льюисона про Иран в 13 в.:
AlÇ al-Dawla al-Semnani (1261–1336) was born into a powerful, land-owning family with obvious parallels to the Juwayn¥s.1302
However, where the Juwayn¥s served in the central Diwan, the SimnÇn¥s remained initially in Khorasan serving the governors there and were well placed in Arghun’s court when he eventually came to the west, reigning from 1284–91. The young SemnÇn¥ entered the court in 1275–6, when he was fifteen years old, at the encouragement of his paternal uncle and it was his wont to engage in religious disputes with the Buddhists who were favoured by Arghun. What is interesting in SemnÇn¥’s case is his relationship with his master, the supposed scourge of the Muslims,1303 Arghun Khan. In 1284 during a battle between the forces of Arghun and Sultan Aªmad’s son-in-law Al¥nÇq, SemnÇn¥ had a vision which was to redirect his life. Much against the wishes of Arghun he eventually determined to leave the D¥wÇn and to devote himself to asceticism and the Sufi path.
