Book excerpt: In the practice of karate, throughout the world and all levels, there is one sure constant - the Kata. These formal sequences of karate techniques form the basis of all proper practice, and their range in degree of difficulty means that they can be taught throughout a student's career. This new edition, which first appeared as two separate volumes, covers the first thirteen Shotokan Kata: Heian Shodan, Heian Nidan, Heian Sandan, Heian Yondan, Heian Godan, Tekki Shodan, Bassai-Dai, Empi, Sochin, Jion, Hangetsu and Nijushiho. Fully illustrated with photographs of each move, the accompanying text explains each sequence fully and clearly with a thorough investigation of the Kata's 'bunkai' or application. The authors concentrate not only on physical conditioning, but also on the correct mental and spiritual attitude. Complete with an exploration of the historical background and development of the Kata, this book will prove indispensable to all students of karate.
