No thirst for blood he had, oh indeed. O Brother! Grand feelings surged within your breast.

This couplet beautifully describes a noble spirit. It says, "Even when thirsty, it wasn't for blood." This means the person's motivations were never violent or destructive. Instead, their heart, their very being, overflowed with a magnificent and grand emotion. It speaks of a deep, selfless love, courage, or perhaps a profound sense of duty that guided them, rather than any desire for harm or vengeance. It celebrates a pure and powerful inner strength, emphasizing that their actions stemmed from a place of great virtue and not aggression.
