Speaking ‘Tzu Lu‘, the Master said: “Have you ever heard of the six shadows which attend six great virtues?” “No,” he replied. “Sit down then, and I will tell you. Love of goodness without the will to learn casts the shadow called foolishness. Love of knowledge without the will to learn casts the shadow called insensibility.
Love of candor without the will to learn casts the shadow called rudeness. Love of daring without the will to learn casts the shadow called turbulence. Love of firmness without the will to learn casts the shadow called eccentricity.”
