What does You talk of sacrifice he knew the meaning of sacrifice mean?

The phrase "You talk of sacrifice; he knew the meaning of sacrifice" suggests a distinction between mere discussion of sacrifice and genuine experience of it. It implies that while some may speak about the concept or idea of sacrifice, there are individuals who have lived it, understanding its depth and implications through personal experience. This highlights the difference between theoretical knowledge and the profound understanding that comes from facing real challenges and making significant personal sacrifices.
