Query: Great for beginners

Very interesting approach: a brand new white belt teams up with an experienced black belt to provide fascinating insights into karate. The book is arranged in five sections in a manner similar to Musashi's famous book of five rings. The first chapter covers foundational concepts while each of the other four chapters describe one of the four Taikyoku series kata in detail. It's a pretty short work, but fun to read and very instructive for beginners. There are some essential basics (dojo lore) like how to understand kanji, count in Japanese, and decipher how ranks and belts are used. There are also a few insightful gems such as how "blocks" are used offensively. This book probably won't interest experienced practitioners all that much but beginners should find it illuminating. A very worthwhile read.Lawrence KaneAuthor of Surviving Armed Assaults, The Way of Kata, and Martial Arts Instruction
