The more you dedicate your life to the sword, the more likely you will lose your way. Since not one man is an island unto himself. Simply poetry. Just like the poem from John Donne that reiterates how the interconnectedness of life is what makes every human special and that seclusion into one's goals or vices can lead to utter chaos for that individual. Yagyu Sekishusai Muneyoshi seems to have related to this more than anyone when he was in his youth, trying to best his future master. Looking at Kami'Izumi Ise No Kami Hidetsuna's face, you could see the calmness radiate such strength of a man who realized he is not strong on his own.
