Universal Message of the Bhagavad Gita: An Exposition of the Gita in the Light of Modern Thought and Modern Needs, Volume 3 Hardcover – December 1, 2001

This is one of the best explanations of the Bhagwat Gita and that is because the author Swami Ranganatanandaji was himself a realized master, so that makes the core difference.

This is one of the best books I've ever read. Author quotes contemporary authors from all over the world, and tries to bring in unity to the thought process. A must read for people seeking spiritual progress.
