The eternal oud is still mysterious for many, in general and in particular, although it is practiced by everyone every day, and although it constitutes the essence of religious behavior, perhaps its ambiguity is in particular, from the way it is presented with a lot of confusion and thumb. The eternal oud is no longer an ancient behavior, idea or myth, but rather a comprehensive religious system that includes the main components of any known religion, has beliefs, myths and rituals of its own, where we see that it is present today in our behavior and our lives clearly and we have to reveal the beautiful awareness of it and the naughty awareness of it, so these are these Valentine is what they make either a material for creativity or a substance for oppression and tyranny. On the other hand, this eternal oud system has become a habitat of fundamentalist doctrines, which disguised towards Salafism and the past, when it circulated religiously and became a compulsive and authoritarian system practiced by fundamentalists in religion and politics in particular and has become a negative system. As for literature and art, the great creators invested in their works as a deep and functional legend, and in science its echoes appeared with the theories of the mirror universe and the scholars of the Khamini and in the interpretations of the theory of the big explosion. The books that discussed the eternal oud are very few and most of them emphasize one aspect of it, but this book tries to examine the entire eternal oud system of beliefs, legends and rituals, and even is free from poetry, novel, photography, universe science and physics in particular. The book tries to answer the following question: Is the eternal oud a beautiful idea? Or is it a religious idea that wears philosophy and science?
