This research book deals with the economic ideas delineated in the Manusmriti composed originally before 2300 B.C. by Manu, a mythical sage and the first King of divine origin in India. The Manusmriti presents itself as a discourse given by Manu to a group of seers, who beseech him to tell them the "law of all the social classes". It became the standard point of reference for all future texts that followed it. According to Hindu tradition, the Manusmriti records the words of Brahma. This research work explains the economic ideas of Manu with effective commentaries.
