Musashi isn't telling you to abandon feeling—he's suggesting that love and grief, while legitimate, can become prisons if they're your only reference point for meaning. The radical move here is treating service to others as a *higher* emotional register, not a suppression of emotion. A person grieving a loss who volunteers at a hospice isn't denying their pain; they're discovering that their capacity for care, sharpened by loss, becomes useful in ways private sorrow never could. That's the point: your feelings are real, but they needn't be your destination.
