Most people (even in India) have not heard the name of Anu-Gita. This is so because, although Anu-Gita is an important part of the Mahabharata, no scholarly study of it, in a simple language, has so far been published. This gap will be filled by this pioneering book, which explains under what circumstances was the Gita taught by Lord Krishna to Arjuna, for the second time. This book is divided into two parts. Part I presents the Sanskrit-shlokas of Anu-Gita, along with their translation in simple English. Part II explains the main points of similarity, as well as dissimilarity, between Gita and Anu-Gita.
