A sword is useless in the hands of a coward. The mighty sword of the Lotus Sutra must be wielded by one courageous in faith. Then one will be as strong as a demon armed with an iron staff.
The Strategy of the Lotus Sutra
Spur yourself to muster the power of faith. Regard your survival as wondrous. Employ the strategy of the Lotus Sutra before any other. “All others who bear you enmity or malice will likewise be wiped out.”4 These golden words will never prove false. The heart of strategy and swordsmanship derives from the Mystic Law. Have profound faith. A coward cannot have any of his prayers answered.
