What are the best books, writings and great works by traditional scholars and Rabbis in Judaism dealing with the topic of humility? I want very traditional and age old works the likes of which you would see on Sefaria.com . For example the Sefer Hasidim (Book of the Pious) deals with being pious and aspects of what one would call Jewish Asceticism. What would you suggest? I know many books are in Hebrew and my Hebrew is very bad so English is requested. Fell free to suggest ANY good books in any language though.
I would recommend Chovot Levavot, Orchot Tzaddikim and Mesilat Yisharim. All have chapters/sections on humility (Chovot Levavot has a section on Jewish 'asceticism', as does Mesilat Yisharim), all are age old and traditional, authored by great scholars and sages, and all are on sefaria in English.
