H. P. Blavatsky

Muluk‐Taoos. From Maluk, “Ruler”, a later form of Moloch, Melek, Malayak and Malachim, “messengers”, angels. It is the Deity worshipped by the Yezidis, a sect in Persia, kindly called by Christian theology “devil worshippers”, under the form of a peacock. The Lord “Peacock” is not Satan, nor is it the devil; for it is simply the symbol of the hundred eyed Wisdom ; the bird of Saraswati, goddess of Wisdom; of Karttikeya the Kumâra, the Virgin celibate of the Mysteries of Juno, and all the gods and goddesses connected with the secret learning.
