There are more dozens of spiritual, intellectual, magical and other movements, connected at first to the ground of Europe, and now even spread to all continents, that claim to have roots in Ancient Greece, precisely in the Apollo's temple in Delphi. All those teachings, movements and groups have several common features and believe in several common regularities, no matter the fact that their ways have not interwoven during the written history. Those similarities, and first of all so called Great Laws are characteristic of exclusively those spiritual movements and can not be connected to any other movements. With the help of that, we have many reasons to believe in the common roots of those teachings.

So, for example in The Book of Movement, which is one of those movements, (which we cannot connect to the old Asian Book of Changes I Ching) we can find a number of similarities with many shamanistic realizations from the ground of Latin America, Africa, Europe and Asia. It is possible, if we look carefully enough, to draw the parallel between The Teaching of the Fire, which is also one of the movements in the Parallel Knowledge, and some Teachings of Yoga. It is not necessary to give any more examples. The point is that every one of these teachings or movements are crucially different among themselves; it is possible to draw the parallel for every individual teaching with some movements, teachings, religions of other continents, time, mission and content. Also, recorded historical way of each of these teachings is such that we cannot find anywhere their common points, mutual cooperation, communication or interaction. Having this in mind, it is difficult to comprehend rationally how it is possible that all those teachings lean on identical laws (The Great Laws), whose formulation is absolutely identical, then the formulation is written in the identical spiritual language which in all those teachings shows the same regularities.

Not counting the documents from the period of Ancient Greece and Ancient Rome, the first documents that we can find about these types of knowledge appeared during the Middle Ages, and also during the centuries of Classicism and particularly during the age of Romanticism (18th and 19th century) but the first more serious studies about them appeared only in the second half of the 20th century. The first systematization of these types of knowledge appears in the book "Parallel Knowledge and The Teaching of The Fire" (1986.). At that year for the first time in public has appeared the term Parallel Knowledge as the collective name for all those movements. We find the term suitable and logical, because the movements are based on the same principles, the same sources, but besides that they did not have the knowledge of each other. 

In any case, no matter the real origin of different movements, collectively named the Parallel Knowledge, it is absolutely certain that the followers, or, even transmitters of those teachings have had through time some sort of communication and adjustment to space and time in which they have happened to be in. Perhaps that is the answer to the question: why there are so many differences among them, why there are so many completely different influences and similarities with some other spiritual ways, religions, science and mistakes.

We hope humbly that in this way we will contribute at least a little to opening of that subject in such transparent way and induce creative investigations in this field.
