This book is a veritable feast of knowledge. I love books about temples, ancient and modern. I read heavily at the feet of LDS and non-LDS scholars and their treatments of ancient temples; this book is in my top three. The articles are written by some of the LDS community's top scholars. Dr. Parry's article on the Garden of Eden is mind-blowing; Lundquist's treatise on temple preliminaries is a must-read; Nibley's article on the Sacred and the Symbolic is tremendous. Obviously you want agree with every author (the work is an Edited compilation); however, the book merits accalades and is a sound piece of faith and scholarship.
This book is one of the best written documents explaining some of the symbolic elements of the temple as well as its importance throughout history. It is a must-get for anyone who really is serious about understanding the covenants and blessings of the temple. Some of it is kind of hard to read because it was written by very highly educated persons.
