Will of Fire

The is a recurring element throughout the Naruto series. It is an ideal rooting from the belief of the Senju Clan Ancestor that love is the key to peace. It would eventually become the life philosophy Hashirama Senju lived by and held, which has since been passed on to many ninja from Konohagakure as a part of their spiritual heritage. The 'Will of Fire' states that every true Konoha 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, in hopes that he would in turn pass it on to his and Kurenai's child.

According to Madara Uchiha, the Uchiha clan's "Destiny of Hatred" is fated to clash against the Will of Fire, as he believed that Sasuke Uchiha and Naruto Uzumaki are destined to fight.
