I actually chose the user name after the type of ancient Iranian sacrificial priest, which is cognate with the Vedic 'hotar' priest. 'Zaotar' literally meaning 'invoker.' As an aside, the beginning of Surah 96 (allegedly the first revelation given to Mohammed) starts with the same concept albeit in Arabic, "INVOKE the name of the Lord," (iq'ra thus being the first revelatory word that Mohammed allegedly received), paralleling the common liturgical Syriac and Judaic phrase, which later Muslims have misinterpreted as meaning just 'Recite' in the name of your Lord. So in that sense, my posting name is a corrected version of how the Qur'an should be understood from the start -- an invocation of the deity, in a liturgical context (aka qeryana), not a recitation.
Zarathustra was allegedly himself a zaotar. I like the name for a lot of different reasons, one of which is it reminds me of Nietzsche's hilarious idea that since Zarathustra was the first to commit the error of dividing the world into good and evil, he should also be the first to denounce his mistake.
Also, I think Central Asian and Indian culture and civilization deserve much more attention and acclaim than they've historically gotten ... though I myself have no personal connection to Central Asia or India.
For some reason there's no good English webpage on the subject, but this German wiki page gives a good explanation of the zaotar (although it describes it as a Zoroastrian priest, but it is more than that -- it was the broader category of ancient Indo-Iranian priest, and Zoroastrianism just inherited it).http://de.wikipedia.org/wiki/Zaotar
