leader of these Angels is known as Tawûsê Melek, and the others are better known by the names of their earthly incarnations/representations: Fexreddin, Sheikh Shems, Nasirdin, Sejadin, Sheikh Obekr, and Shex Hesen (Şêxsin). The Yazidi pantheon contains a total of 365 holy figures venerated by Yazidis, designated by various special terms including Xudan, Xas, Mêr and Babçak. According to Yazidi beliefs, God is almighty and absolute, and the Xudans are a part of His power, moreover, in relation to nature, Yazidis believe in Xudans for most of natural elements and phenomena and they are regarded as divine powers that have control over these phenomena.
