Man lives in two kinds of worlds, which he has to unite in himself. On the one hand he is the cornerstone of the outer, material creation, in which he is called the crown of creation and he is praised as such. On the other hand, he is the starting point of the pure spiritual world, which with him has reached the first stage of complete free self-awareness. So, on the one hand he is the beginning of chain and, on the other hand, the end of a chain, and he has to find in himself (for that purpose life was given and its free development) the missing link with which he can make those two chains as one. What would you say, if I told you that Einstein was not the first one in the West who wrote about the unity of space and time? What would you think, if I told you that, in respect with the nature of the Universe and man, the most complex and profound metaphysical system was created in the 19th century by Jakob Lorber, and since then almost completely disregarded by all mainstream Western thinkers? This is the most unlikely book ever If you want to learn about the humanity's efforts in building explanatory systems, meant to offer an understanding of the world and our part in it, then you will have to look at the thinkers living in the Indian continent, the ones living around Himalayan Mountains, the Chinese, the Japanese, the European thinkers, the ancient Egyptians, the Jews, the Arabs, etc. Now, if we will try to look at these efforts taking into account the scope of their theories and the depth of their arguments, we could see that almost all these systems appear as more or less underdeveloped, when they are compared with Kashmiri Shaivism (Pratyabijna School) . This system is the work of a series of highly educated spiritual masters, during hundreds of years. It was, for me, the most complex and the most profound metaphysical system I ever encountered. Until I met Lorber When I am referring to the complexity of a metaphysical system, I think about covering almost all the basic questions about the Universe and about us. Namely: Is there anybody responsible for the creation of the Universe? What is the fabric of the Universe and its building blocks? What is its purpose, if there is any? What are its laws and how does it function? What is space and what is time? From where are we coming and where are we going? Is there anybody responsible for our creation? What is the structure a human being and which are our building blocks? What is the relation between us and the Universe? It is important to highlight that I am not looking at these systems in search for the Truth; I am just trying to see if there is any wisdom in them Namely, I am interested to see if these systems are coming with intelligent answers to all these important questions, and their answers are sound and useful, and in line with the scientific data at hand. Every system I looked into (and I studied both the well known Western systems as well as the Eastern systems) was either partial, or with a more-or-less fable argumentation. With one notable exception: the Kashmiri Shaivism (which became known to the West long after Lorber death ). After I read "The Great Gospel of John" I realized I've found a similarly complex and sound explanatory system. Which, in its main points (God, Creation, the human being) is even more interesting then Kashmiri Shaivism So, what several spiritual masters created in hundreds of years having Hindu philosophy as foundation, Lorber accomplished on its own, in only 13 years, having Christian theology as foundation And that is exactly why I earlier labeled this as "the most unlikely book ever "
