The Concentricity of The Cosmos is the twentieth instalment in the Little Blue Book Series and comprises of the thirty-fourth and thirty-fifth discourses of the Monodoxy which is itself the first disquisition of the founding book of Astronism, titled the Omnidoxy. The Concentricity of The Cosmos discourses explores the notion that The Cosmos is structured upon concentric patterns and subsequent inferences are made as to why and how this could be. Secondly, the discipline of study of instrument theory is introduced which deals with the theoretical rather than the applicable aspects of instruments of study which remain central to Astronist philosophical investigations. 
 
 
The Little Blue Book Series was created and first published by Cometan himself as a way to simplify and commercialise the immensity of the two million word length of the Omnidoxy into smaller, more bite-size publications. A successful series from its very first published entry, the Little Blue Book Series has gone on to become a symbol of Astronist commercial literature and a way for Cometan’s words to reach readers of all ages and abilities who remain daunted by the beauty and yet the sheer extensiveness of the Omnidoxy as the longest religious text in history.
