The division into 15, 150 and 180 of books, chapters and topics respectively was probably not accidental, states Olivelle, because ancient authors of major Hindu texts favor certain numbers, such as 18 Parvas in the epic Mahabharata. The largest book is the second, with 1,285 sentences, while the smallest is eleventh, with 56 sentences. The entire book has about 5,300 sentences on politics, governance, welfare, economics, protecting key officials and king, gathering intelligence about hostile states, forming strategic alliances, and conduct of war, exclusive of its table of contents and the last epilogue-style book.
