sa bhuyah pancajanyayam
putran ajanayad daksah
sah—Prajapati Daksa; bhuyah—again; pancajanyayam—in the womb of his wife Asikni, or Pancajani; ajena—by Lord Brahma; parisantvitah—being pacified; putran—sons; ajanayat—begot; daksah—Prajapati Daksa; savalasvan—named the Savalasvas; sahasrinah—numbering one thousand.
When Prajapati Daksa was lamenting for his lost children, Lord Brahma pacified him with instructions, and thereafter Daksa begot one thousand more children in the womb of his wife, Pancajani. This time his sons were known as the Savalasvas.
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 lost—when they returned home, back to Godhead—he 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.
