Srimad Bhagavad Gita with the Gloss of Sridhara Swami, translated by Swami Vireswarananda
This is a Bhagavad Gita with high quality English translation, accompanied by a commentary by Sridhara Swami, the famous medieval saint who comments word by word every verse with a lot of devotion despite formally belonging to Sankara school. It is a new way to see how our acaryas commented the scriptures, especially if you are used to lengthy commentaries by modern day gurus. Sridhara Swami´s authenticity has been corroborated by Sri Caitanya Mahaprabhu Himself so this commentary is certainly of great use to Gaudiya Vaishnava sadhakas.
This Bhagavad Gita had a great impact on me, because it comments the verses word by word, often giving its synonyms so that the reader understands perfectly what Krishna wants to convey. I learned a lot from Prabhupada´s Gita, but there were still many places which I simply did not comprehend or was quite unsure about. Sridhara Swami´s commentary clarified many things or misconceptions which I had, and prepared me for studying other works of our acaryas, where it is customary to offer commentaries following the word for word style. If you want to study Maharajji´s books in original, this Gita would be, in my opinion, a great preparation. And lastly, the translation is excellent and it has helped me a lot in the process of learning sanskrit.
