An analysis of the ideology and practices of contemporary terrorism shows the amazing coincidences with the ideology and methods of struggle of the Russian revolutionary of XIX century Sergey Nechayev, who wrote the "Catechism of a Revolutionary" (the book was published in 1871). As for today's terrorists, who fight against the western civilization, as can be seen, "Catechism of a Revolutionary" is fully consistent with the ideology and methods of their struggle. Many of the provisions and recommendations of the "Catechism" literally fit their methods of struggle. We do not know, whether the ideologists and leaders of modern terrorists read this "Catechism", but it is so. On the other hand, some modern esoteric claim that around the beginning of XXI century began "era of separation" between Good and Evil, which replaced "era of mixing" of Good and Evil, which lasted about 2,160 years (150 BC - 2007\2008 year AD). How long will last the era of separation, and how this relates to the age of the apocalypse foretold in the Book of Revelation of Holy Bible? The author examines in detail all of these questions in this brochure.
