Heroic Courage
Rise up above the masses of people who are afraid to act. Hiding like a turtle in a shell is not living at all. A samurai must have heroic courage. It is absolutely risky. It is dangerous. It is living life completely, fully, wonderfully. Heroic courage is not blind. It is intelligent and strong.
Heroic courage as it is described here means being able to make smart decisions and act on them even in stressful situations. Sometimes it is more courageous not to use your fighting techniques.
