The book starts with the explanation given by Vishnu to his consort Lakshmi about the evolution of Universe and of human beings. It is said that there is a total of eight aeons, or yugas, and we are currently in the seventh yuga called Kali Yuga, the age of deterioration. It is believed that for each yuga there is a demon that will be destroyed by Vishnu. In the first yuga, Kroni was born. Vishnu fragmented him into six pieces and each fragment will incarnate as demon in each Yuga. The first four yugas are said to be the Neetiya Yuga, Chatura Yuga, Nedu Yuga and Kretha Yuga. These four yugas do not have parallels in the mainstream Hinduism.
