The Upanisads do not contain any readymade consistent system of thought. At first sight they seem to be full of contradictions. Hence arose the necessity of systematizing the thought of the Upanisads. So the philosophy of Upanisads was systematized through Brahma-Sutras from Brahma-Sutras we find that there were other schools of Vedanta which had then own following. We find the names of Audulomi, Badari, Jaimini, Asmarathya and others mentioned. All the sects of India now hold their work to be the great authority and every new sect starts with a fresh commentary on it, without which no sect can be founded in this country.
This book so clearly gives the meaning, translation and commentary on Brahma sutras that it can be easily understood by the readers, without texing their mind.
