Sacrifice... By its strictest definitiontakes somthing precious in exchange for the appeasement of a higher power. An abiding devotion to a cause that cannot be satisfied with a simple promise. Because an oath... No matter how solemn asks nothing in return. While true sacrifice demands unspeakable loss.
Sacrifice demands the surrender of things we cherish above all else. Only out of the agony of those losses can a new resolution be born. An undying devotion to a cause greater than one's self. And a moral duty to see a journey through... to its absolute completion.
