I think he's relating to the "book of five rings" / "art of war" way of writing books. Theres many big long books that are merely churned out, or are written before an author has reached a point of completeness about the subject he's writing on. Worse, they could be written as "wines of fear" where they are written not to directly offend anyone. On the other hand, there are a few beautiful books that are short, yet establish mental frameworks that cover all the other books. The book of five rings is touted as one. Personal example: There's volumes of business books that all harken back to people being some mixture of evangelist, maven, or relater. Books like "the human fabric" or religious books like the "bhagavad gita" establish the same framework.
