A report on Orach Chayim, Joseph Karo and Halakha

Orach Chayim, modern Hebrew: Orech Chayim (אורח חיים; manner/way of life) is a section of Rabbi Jacob ben Asher's compilation of Halakha (Jewish law), Arba'ah Turim.

Rabbi Yosef Karo modeled the framework of the Shulkhan Arukh (שולחן ערוך), his own compilation of practical Jewish law, after the Arba'ah Turim. Many later commentators used this framework, as well.

By 1555, Joseph Karo was already a resident of the village Biriyya near Safed, during which year he completed writing the first order of the Shulhan Arukh, Orach Chaim.

Beit Yosef (בית יוסף), a commentary on Arba'ah Turim, the current work of Jewish law in his days. In this commentary Karo shows an astounding mastery over the Talmud and the legalistic literature of the Middle Ages. He felt called upon to systematize the laws and customs of Judaism in face of the disintegration caused by the Spanish expulsion.

Orach Chayim ("The Way of Life"): worship and ritual observance in the home and synagogue, through the course of the day, the weekly sabbath and the festival cycle.

The Beit Yosef and the Shulchan Aruch of rabbi Yosef Karo (1488–1575). The Beit Yosef is a huge commentary on the Tur in which rabbi Karo traces the development of each law from the Talmud through later rabbinical literature (examining 32 authorities, beginning with the Talmud and ending with the works of rabbi Israel Isserlein). The Shulchan Aruch (literally "set table") is, in turn, a condensation of the Beit Yosef – stating each ruling simply; this work follows the chapter divisions of the Tur. The Shulchan Aruch, together with its related commentaries, is considered by many to be the most authoritative compilation of halakha since the Talmud. In writing the Shulchan Aruch, rabbi Karo based his rulings on three authorities – Maimonides, Asher ben Jehiel (Rosh), and Isaac Alfasi (Rif); he considered the Mordechai in inconclusive cases. Sephardic Jews, generally, refer to the Shulchan Aruch as the basis for their daily practice.
