The book is a condensed form that focuses on the major themes in Bhagavad Gita. Authored by Swami Dayananda Saraswati, the book is a great addition to your collection if you want to revisit the core principles of the Bhagavad Gita. It focuses on the atman or soul which is a part of self, importance of duty, bhakti yoga, karma yoga, and how surrendering to God is the ultimate form of devotion. The book is quite interesting and eye-opening. Purchase it from Giri UK.
