A Ruthless Model
“The selection of a primary disciple is not an easy thing. It is often marked by blood.”
Yamashita looked at me significantly. The founder of his style, Ittosai, dealt with this issue centuries ago and had left his successors through the generations a ruthless model. The master, blessed with two remarkable students of apparently equal skill, had brought them together. He had placed the scrolls of the style and the document of succession on the ground, along with a ceremonial sword. Then he had calmly informed the two disciples that the individual who left the room alive would be his successor.
