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.
Those who die, merely suffering the woes of life like cats and dogs, are they human beings? The worthy are those who, even when agitated by the sharp interaction of pleasure and pain, are discriminating and, knowing them to be of an evanescent nature, become passionately devoted to the Atman. This is all the difference between human beings and animals.
-Swami Vivekananda
