Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The shore of the lake was surrounded by clusters of pious trees and creepers, rich in fruits and flowers of all seasons, that afforded shelter to pious animals and birds, which uttered various cries. It was adorned by the beauty of groves of forest trees.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
It is stated here that Bindu-sarovara was surrounded by pious trees and birds. As there are different classes of men in human society, some pious and virtuous and some impious and sinful, so also among trees and birds there are the pious and the impious. Trees which do not bear nice fruit or flowers are considered impious, and birds which are very nasty, such as crows, are considered impious. In the land surrounding Bindu-sarovara there was not a single impious bird or tree. Every tree bore fruits and flowers, and every bird sang the glories of the Lord — Hare Krsna, Hare Krsna, Krsna Krsna, Hare Hare/ Hare Rama, Hare Rama, Rama Rama, Hare Hare.
