Prajapati Daksa was so named because he was very expert in begetting children. (The word daksa means expert.) First he begot ten thousand children in the womb of his wife, and when the children were lostwhen they returned home, back to Godheadhe begot another set of children, known as the Savalasvas. Prajapati Daksa is very expert in begetting children, and Narada Muni is very expert in delivering all the conditioned souls back home, back to Godhead. Therefore the materialistic experts do not agree with the spiritual expert Narada Muni. but this does not mean that Narada Muni will give up his engagement of chanting the Hare Krsna mantra.
