Demonology. Demons' masks.
No, they don't have wings, fangs or tails and they don't drink the blood of innocent infants. But they live here on Earth and they're dangerous. They resemble usual people. It's possible to recognize them by the extremes that overfill their souls and by their behavior. They can be noticed for their pridefulness, hatred for lower classes or worshipping the upper class. Their fears and love speak for themselves. The slaves to golden idols and golden idols themselves. All those slaves of the evil make this life unbearable and resembling hell. It's necessary to avoid the evil as it smears souls and turns life into hell while filling it with pain.
Such concepts as demons, angels, god, paradise, hell, sins, harmony, etc. - all of them are abstract symbols and metaphors that have their reflection in real life. Such religious concepts are not real objects or phenomena, as they may think. The word "demon" shouldn't evoke the image of some monster in a horror. In our concept, it may be some person who may possess particular traits or spiritual state.
I will teach you, my dear friend, how to see and avoid the evil and it will definitely make your life better.
