In communication with the medium Irene Pacheco Machado, after offering us a work centered on the Sermon on the Mount, Luiz Sérgio returns with his unmistakable style of conveying everything he learns in the spiritual world. Now, he even explains to his readers about the passage of the spirit through the different kingdoms of Nature, following the path of the spiritual principle, in constant learning toward God, the Creator of all that exists. According to the author himself, this book is not filled with difficult words taken from dictionaries to please doctors of law, but was written with the simplicity of his heart, eager to transmit the knowledge acquired in the educational institutions of the higher spiritual world.
