What is the essence of kedusha (sanctity)? What is the difference between the kedusha of Shabbat, Yom Tov and Yom Kippur; or between the kedusha of Land of Israel, Jerusalem, the Temple, and the Holy of Holies? How is kedusha created and how is it removed? Are all forms of kedusha different levels of the same essence, or are there fundamental differences between them?
Kedushat Aviv, a trailblazing work on the sanctity of time and place, is a momentous contribution to Torah literature. With vast sweep, analytic sharpness, penetrating depth, and complete mastery of the field, Rav Aharon Lichtenstein zt”l encompasses these vast topics and presents them to the reader in an orderly and rigorous manner. He clarifies fundamental concepts, establishes basic principles, and explicates rabbinic disputes with subtlety and precision. Rav Lichtenstein wrote sections of this book over the course of the years, and the remainder of the book was completed after his passing on the basis of recordings of his lectures.
Prepared and edited by Rabbi Shai Lichtenstein. Assistant editor: Rabbi Chaim Navon. With detailed source and subject indexes.
