丘处机
Genghis Khan summoned and met the Daoist master Qiu Chuji (1148–1227) in Afghanistan in 1222. He thanked Qiu Chuji for accepting his invitation and asked if Qiu Chuji had brought the medicine of immortality with him. Qiu Chuji said there was no such thing as a medicine of immortality but that life can be extended through abstinence. Genghis Khan appreciated his honest reply and asked Qiu Chuji who it is that calls him eternal heavenly man, he himself or others. After Qiu Chuji replied that others call him by that name Genghis Khan decreed that from thenceforth Qiu Chuji should be called "Immortal" and appointed him master of all monks in China, noting that heaven had sent Qiu Chuji to him. Qiu Chuji died in Beijing the same year as Genghis Khan and his shrine became the White Cloud Temple. Following Khans continued appointing Daoist masters of the Quanzhen School at White Cloud Temple. The Daoists lost their privilege in 1258 after the Great Debate organized by Genghis Khan's grandson Möngke Khan when Chinese Buddhists (led by the Mongol-appointed abbot or "shaolim zhanglao" of Shaolin monastery), Confucians and Tibetan Buddhists allied against the Daoists. Kublai Khan was appointed to preside over this debate (in Shangdu/Xanadu, the third meeting after two debates in Karakorum in 1255 and 1256) in which 700 dignitaries were present. Kublai Khan had already met Haiyun in 1242 and been swayed towards Buddhism.
