The commentary of Shankara on the Gita is regarded as an outstanding specimen of Indian scholarship. Text and translation are given. The inclusion of 'word index' has added to the worth of the book.
Take up one idea. Make that one idea your life -- think of it, dream of it, live on that idea. Let the brain, muscles, nerves, every part of your body, be full of that idea, and just leave every other idea alone. This is the way to success, and this is the way great spiritual giants are produced. Others are mere talking machines.
-Swami Vivekananda
