They worship 'Taus Melek'--'The Peacock Angel'--you know: Lucifer. They believe that when God redeems even him that when Lucifer takes up his former arch-angel position that he will have special favor for the Yezidi of Kurdistan.
From what I understand of Yezidism they are monotheists who worship god... but they also believe that god is remote from the earth and has left a group of seven angels in charge, lucifer being chief among these... Lucifer was so sad when he was kicked out of heaven that he cried and creid until the fires of hell were extinguished! And then he was restored to his former place of honor... or something like that... Good God, there is so much disinformation and misinformation about the Yezidi out there (and outright bad scholarship by people w. agendas - Anton Lavey is good example) that it is really hard to tell....
Anywho, thanks for the link, I'll check it out. Here's another good one too, BTW:
The followers of the Yezidi religion, who have variously referred to themselves also as the Yazidi, Yazdâni, Izadi, and Dasna'i, have often been pejoratively referred to by outsiders as "devil worshippers." They constitute less than 5% of the Kurdish population. At present they live in fragmented pockets, primarily in northwest and northeast Syria, the Caucasus, southeast Turkey, in the Jabal Sanjâr highlands on the Iraqi-Syrian border, and regions north of the Iraqi city of Mosul.
As a branch of the Cult of Angels, Yezidism places a special emphasis on the angels. The name Yezidi is derived from the Old and Middle Iranic term yazata or yezad, for ,1 angel," rendering it to mean "angelicans." Among these angels, the Yezidis include also Lucifer, who is referred to as Malak Tâwus ("Peacock Angel"). Far from being the prince of darkness and evil, Lucifer is of the same nature as other archangels, albeit with far more authority and power over worldly affairs. In fact, it is Malak Tâwus who creates the material world using the dismembered pieces of the original cosmic egg, or pearl, in which the Spirit once resided.
Despite the publication of (reportedly) all major Yezidi religious scriptures, and the availability of their translations, the most basic questions regarding the Yezidi cosmogony are left to speculation...
