Brahma Sutras systematizes the philosophy of the Upanishads in 555 aphorisms. In this book the original aphorisms are given in Devanagari followed by word-for-word English rendering, and the interpretation of the sutra according to Shankaracharya. The introduction contains a comparative study of the bhashyas of Shankara, Ramanuja, and Nimbarka.
When we have become free, we need not go mad and throw up society and rush off to die in the forest or the cave; we shall remain where we were, only we shall understand the whole thing.
-Swami Vivekananda
