Kata
The purpose of learning kata is not just for the sake of learning them. The purpose of learning kata lies in tempering and disciplining oneself in mind body and spirit.
Kata training with the correct instruction contains everything you need to know about karate techniques and how to apply them. Each move in a kata provides a snap shot of a technique. That snap shot should be corrected by your instructor so you develop into the best karate technician you possibly can.
Philosophy
Always remember karate form and practice is about the physical. Karate-do encompasses both the physical and the philosophical aspects of the art. As Funakoshi Gichin Sensei said:
"True karate is that in daily life one's mind and body be trained and developed in a spirit of humility, and that in critical times, one be devoted utterly to the cause of justice."
Another earlier commentary on the correct overall development of karate-ka both physical and philosophical comes from Bushi Matsumura:
“To all those whose progress remains hampered by ego-related distractions, let humility, the cornerstone upon which karate rests, serve to remind one to place virtue before vice, values before vanity and principles before personalities”
Sokon Matsumura known as Bushi (warrior) Matsumura was the karate teacher to both of Funakoshi Gichin Sensei’s principal teachers Itosu Sensei and Azato Sensei.
Like all good philosophies the philosophy that underpins karate-do is that you must try to become the very best person you can become.
