The 'Will of Fire' states that every true Leaf shinobi must love, believe, cherish and fight for the village's sake, as many previous generations had done before them.
According to Hiruzen Sarutobi, the "Will of Fire" is what gives the shinobi the strength to continue fighting against all odds, building willpower and strength of character. It is also symbolic of the hopes and dreams of the previous generation being passed to the next; for example when Asuma Sarutobi was killed, his hopes and dreams were passed to Shikamaru Nara, who would in turn pass it on to Asuma and Kurenai Yuhi's child.
