The peculiarity of Sergei Ivliev's style is his ability to combine scientific accuracy with poetic imagery, which makes reading not only informative, but also aesthetically pleasing. His other works, such as Journey to the Depths of Consciousness or Bridges Between Worlds, confirm his talent in building literary bridges between science and spirituality. In Man-Universe, the author continues to develop these topics, inviting the reader to dialogue with himself and the world around him. The topics raised in the book are not only questions about the nature of man and his relationship with the cosmos, but also reflections on inner transformation, how to learn to listen to your intuition and find harmony in the chaos of the modern world.
