SB 6.4.10
yuyam ca pitranvadista
deva-devena canaghah
praja-sargaya hi katham
vrksan nirdagdhum arhatha
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
O pure-hearted ones, your father, Pracinabarhi, and the Supreme Personality of Godhead have ordered you to generate population. Therefore how can you burn to ashes these trees and herbs, which are needed for the maintenance of your subjects and descendants?
