Quote: Munenori
It is a disease to be possessed by ideas of victory or of technique. It is also a disease to be possessed by the idea of showing the results of your training. It is a disease to be determined to attack first or, conversely, to wait for the opponent's move. It is a disease even to be possessed by the idea of removing all such diseases. The disease is a state of mind that is rigid and fixed, in whatever situation. All such diseases stem from your state of mind. It is important to control the mind. —From Hei-Ho-Kaden-Sho by Yagyu Tajimanokami Munenori
