Srimad Bhagavatam Canto 04, Chapter 17, Text 12

SB 4.17.12

maitreya uvaca
prthuh prajanam karunam
nisamya paridevitam
dirgham dadhyau kurusrestha
nimittam so ’nvapadyata
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
After hearing this lamentation and seeing the pitiable condition of the citizens, King Prthu contemplated this matter for a long time to see if he could find out the underlying causes.
