Here we are speaking of Svayambhuva Manu, but in Bhagavad-gita we hear about Vaivasvata Manu. The present age belongs to the Vaivasvata Manu. Svayambhuva Manu was previously ruling, and his history begins from the Varaha Age, or the millennium when the Lord appeared as the boar. There are fourteen Manus in one day of the life of Brahma, and in the life of each Manu there are particular incidents. The Vaivasvata Manu of Bhagavad-gita is different from Svayambhuva Manu.
