A notable structure of the treatise is that while all chapters are primarily prose, each transitions into a poetic verse towards its end, as a marker, a style that is found in many ancient Hindu Sanskrit texts where the changing poetic meter or style of writing is used as a syntax code to silently signal that the chapter or section is ending. All 150 chapters of the text also end with a colophon stating the title of the book it belongs in, the topics contained in that book (like an index), the total number of titles in the book and the books in the text. Finally, the "Arthashastra" text numbers it 180 topics consecutively, and does not restart from one when a new chapter or a new book starts.
