Rav Shimile Zelichover [Hashem yinkom damo, who was a great tzaddik and mekubal and had traditions from the Baal Shem Tov] said that the Baal Shem Tov added two more principals of faith to the Rambam's 13.
1] Everything that happens in the world happens because of am yisroel.
2] There are tzadikim in every generation like the avos hakdoshim [as the gemara says יפתח בדורו כשמואל בדורו - meaning that even though Yiftach wasn't as great as Shmuel, for his generation he was considered like Shmuel].
We should all be zocheh to cling to צדיקי אמת!!!
