    …fifth element is synonymous with "void" or "sky", ie "空". For a slightly abstract and colorful philosophy of martial arts, you may enjoy Miyamoto Musashi's Book of Void. https://en.wikipedia.org/wiki/The_Book_of_Five_Rings It is more related to Aether in its Sanskrit origins. "आकाश" If you're willing to make a linguistic leap, you could argue that "nothingness" or "無" constitutes the essential foundation of modern Japanese…

    …for Rastan Saga pop up! (of course it crashed on launch, but still) I named it Musashi, after Shinmen Musashi-no-Kami Fujiwara no Harunobu (新免武蔵守藤原玄信), commonly known as Miyamoto Musashi, who wrote the Book of Five Rings - a book that had a huge effect on me.

    I've enjoyed all the fictionalized accounts, but I think that if you want to learn from Musashi, you should read him directly. That's the Go Rin no Sho aka The Book of Five Rings. Nekopa has recommended the Cleary translation. I will recommend Hidy Ochiai's version, A Way to Victory: The Annotated Book of Five Rings. The annotations and analysis (after each book) really help get…

    This has come up a couple times before. However, specifically for entrepreneurs, the books to read are: 1) How to Win Friends and Influence People by Dale Carnegie 2) Musashi's The Book of Five Rings 3) Gonzo Marketing by Christopher Locke 4) Getting Things Done by David Allen 5) What Management Is by Joan Magretta There are other books, but less relevant in a business context.

    I have to add that people should also read The Book of Five Rings that was written by Musashi. I can't count the number of times I have bought and given away this book. Especially the translation done by Thomas Cleary. Cleary adds another text into the mix "The Book…

    I haven't read the fictional works of Musashi, but his own warrior manual "The Book of Five Rings" is quite good, like "The Art of War". http://en.wikipedia.org/wiki/The_Book_of_Five_Rings

    anyone more interested in the "brain hemispheres" bit (http://f2em.com/#brain-hemispheres) should check out Miyamoto Musashi's collection of writings called "The Book of Five Rings" http://en.wikipedia.org/wiki/The_Book_of_Five_Rings Just some great writing on this idea of being a "balanced" human, and how that influences, informs, and improves your skills. His skills were as a…

    …are), but a discussion of societal development would be lacking without an honest consideration of where the civilized components break down. I would suggest Musashi (http://en.wikipedia.org/wiki/The_Book_of_Five_Rings), Clausewitz, Influence of Seapower Upon History (Mahan), and of course Sun Tzu. While some are more specific than others (Musashi is actually about swordsmanship specifically, but conflict generally)…

    …early stoic philosopher. Note, take some of what they say with a mountain of salt. Their views on things like the overall universe are... a product of their time. For more things I'd say also read The Book of Five Rings by Miyamoto Musashi. And read up on Buddhism possibly with more modern views in the theravada traditions. Feel free to ignore any of the things that make no sense, even the buddha himself said to abandon…

    Can't leave it at one book, because there are four which all tie into a whole: 1. The Book of Five Rings (how to manage yourself) 2. The Art of War (how to manage your campaign) 3. The Prince (how to manage your domain) 4. Proverbs (the wisdom of generations of people in positions of power)

    …happens) and the principle should be clear. Brinkmanship is the name of the game. A study of Martial Arts texts will help in building up the necessary principles/techniques and "mental fortitude". A Book of Five Rings by Miyamoto Musashi is a good starting point.

    …Process (MDMP) [2][3]. I would recommend reading about the MDMP to anyone running a business, or being a technical lead. I'd also recommend the the better known books The Art of War [4] by Sun Tzu and The Book of Five Rings [5] by Miyamoto Musashi. I've had some chuckle at the idea of a book ostensibly on sword fighting being useful in business, until I mention the 9 basic principles Musashi lays out in the first section:…

If you want some inspiration, read the Water Book of the Book of Five Rings by Musashi -- it's freely available as public domain online.

    Nonsense. "A Book of Five Rings" is the strategy book for the pure pragmatist. "Art of War" is for sounding cool at parties.
