What seems natural is to think that a warrior who can hold his own in the face of the unknown can certainly face petty tyrants with impunity. But that's not necessarily so. What destroyed the superb warriors of ancient times was to rely on that assumption. Nothing can temper the spirit of a warrior as much as the challenge of dealing with impossible people in positions of power. Only under those conditions can warriors acquire the sobriety and erenity to withstand the pressure of the unknowable.
