The physical world in which we live and which our senses perceive is only part of an unimaginably vast system of worlds. Most of them are spiritual in nature; they are completely different from the world we know. This does not necessarily mean that they exist in other areas of space - it would be more accurate to say that they exist in other dimensions of existence. Moreover, such deep interpenetration and interaction of different worlds occurs that they become, as it were, integral parts of each other; Moreover, each of them serves as a reflection of the other and, on the contrary, is itself reflected in another world, standing above or below it, changing, transforming and even distorting under the influence of such interaction. And the real world that we see around us is the total result of an infinitely complex set of mutual influences of various areas of the entire universe.
