In this, one of his major works, Maimonides not only explains the principles used in determining which precepts were to be included in the taryag (613) mitzvoth, but also offers an explanation of each one of the commandments.

Volume One details the 248 positive commandments, and Volume Two covers the 365 negative commandments. Written over 800 years ago, this work is a brilliant presentation of the most fundamental teachings of Judaism.
