The commentary of Shankara on the Gita is regarded as an outstanding specimen of Indian scholarship. The translator has accomplished his task in a most praiseworthy manner by giving a faithful translation, without in any way detracting from the strength or clarity of the original commentary.
The book one must read to learn natural sciences is the book of nature. The book from which to learn religion is your own mind and heart.
-Swami Vivekananda
