Rabbi Yosef Karo was born in Toledo, Spain in the year 1488. He lived in Tzfat and created here the Shulchan Oruch, code of Jewish Law.
Without the learning of Halacha, one truly cannot know how to live. The greatness of Rabbi Yosef Karo was that he understood that not everyone can fully grasp the entire Talmud. There needs to be a simple format, a practical way explained to the masses how to serve Hashem on a daily basis. The code of Jewish law should be studied every day and should become a part of every Jew.
