A warrior must have two faces, one of a saint and one of a devil. Without an devil's face, the warrior is a weakling. Without a saint's face, a warrior is a monster. A warrior must be a hero outside of battle and a villain within one. They must control their hate so that their fury may be used in war, but never in peace. The Shehai, the spirit sword, is made out of one's hatred.It is the violence within our souls, the darkness in every heart, the inner evil that we must conquer. Once one learns how to summon the Shehai, they must learn how not to, for it requires an inner anger that should only be felt in the greatest circumstances.
Those who cannot control their hate become the Hiradirge, the fallen Ansei. They are more powerful than the true Sword-Saints, but they are merely violent thugs with the skills of a Sword Singer. All power can and will destroy the untrained wielder. Magic, Sword Singing, Word Eating, all of them will bring forth rampant destruction without restraint. Witness the Pankratosword, the fully unleashed power of the Sword, a single blow that destroys cities. This is the only attack that I know and yet will not share, for it annihilates all, even the user. In the wars at the begging of the world, the same unrestrained powers sunk eight tenths of the world. Such destruction can kill the gods themselves. Unless one declares war on the gods, such power is too dangerous to be in mortal hands.
Through a lifetime of training and meditation, one can strike a balance between your destructive and creative urges. Only I and a few other Tenth-Rank Ansei have ever achieved such a state. It is enlightenment, the ultimate goal of the warrior. Upon our deaths we shall be taked by Tall Papa and join his children, ascending to become lesser gods. The first man who had ever achieved such a state was Onsi, who most know as the God of Weaponcraft. It is his teachings that the arts of the Sword-Singer are based on, arts that I have perfected and written down in this scroll.
