Both Toda Shinryuken and Soke Hatsumi, two renowned martial arts masters, emphasize the importance of embracing flexibility and adaptability in combat and life.

They argue against rigid categorizations such as strong/weak or hard/soft, suggesting that true mastery lies in transcending these dualities and responding naturally and effectively to any situation.

This approach requires cultivating a flexible mindset that allows for dynamic adaptation, ultimately leading to a state of effortless action.
