R. Yehoshua was one of the leading Polish scholars of his day, and was held in great reverence by his contemporaries. He led a Talmudic academy in Cracow which attracted many noteworthy disciples (such as R. Shabtai HaKohen, the Shach).
R. Yehoshua authored Maginei Shlomo, devoted to answering the difficulties raised by the Tosafist scholars against Rashi in his Talmud commentary. He also authored a collection of halachic responsa titled Pnei Yehoshua (not to be confused with the Talmudic commentary of the same name authored by his great-grandson, R. Yaakov Yehoshua [see entry for 14 Shevat]).
People might tell you, “When you come to work, leave your spirituality at home. Don’t bother us with your peculiar lifestyle, your ethics, search for meaning . . . That’s all nice, but this is business. This is the real world.”
There is only one real world, and it belongs to one real G‑d.
