古回鹘文易经是作为道教文献传播到回鹘地区的。道教传到了高昌等地,其中的一些因素,如桃符治鬼等,在新疆还有流传。道教其他的一些因素,如九宫图、内丹、外丹等,在印度、欧洲和中亚地区都有影响。道教西传的载体,主要是留住西域的汉人... 详细信息

古回鹘文易经是作为道教文献传播到回鹘地区的。道教传到了高昌等地,其中的一些因素,如桃符治鬼等,在新疆还有流传。道教其他的一些因素,如九宫图、内丹、外丹等,在印度、欧洲和中亚地区都有影响。道教西传的载体,主要是留住西域的汉人、东来的胡商和一些神职人员;道教主要经过西域和西藏西传。这和宗教与文化的融合、宗教自身之间的融合与吸收、苏非思想的包容性以及信众信仰的复杂性都有关系。
