Rabbi Moshe Chaim Luzzato's famous work, Derech Hashem, is probably the most systematic exposition of Jewish fundamentals ever written, exploring Divine regulation of the world. The author (known by his acronym, Ramchal) begins with our most basic beliefs regarding the existence of G-d and His purpose in creation, and goes on to present the concepts needed to understand all the other important teachings of Judaism. This impressive work opens up this masterpiece to all who wish to study and understand the Ramchal’s profound words. Rabbi Abba Zvi Naiman expertly guides the reader with his clear and accurate translation, interwoven with the Hebrew original, and combines it with his extensive Zichron Eliyahu commentary, which provides references and explores the Ramchal’s vast writings to reveal the depth of his careful and precise language. This edition promises to be a major English classic for the Torah world.
