PURPORT

All the great personalities who increased the population in the beginning of the creation are called prajapatis. Brahma is also known as prajapati, as were some of his later sons. Svayambhuva Manu is also known as prajapati, as is Daksa, another son of Brahma. Svayambhuva had two daughters, Akuti and Prasuti. The prajapati Ruci married Akuti, and Daksa married Prasuti. These couples and their children produced immense numbers of children to populate the entire universe. Vidura's inquiry was, "How did they beget the population in the beginning?"
