SB 9.10.28
krtaisa vidhava lanka
vayam ca kula-nandana
dehah krto ’nnam grdhranam
atma naraka-hetave
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
O pleasure of the Raksasa dynasty, because of you the state of Lanka and also we ourselves now have no protector. By your deeds you have made your body fit to be eaten by vultures and your soul fit to go to hell.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
One who follows the path of Ravana is condemned in two ways: his body is fit to be eaten by dogs and vultures, and the soul goes to hell. As stated by the Lord Himself in Bhagavad-gita (16.19):
tan aham dvisatah kruran
samsaresu naradhaman
ksipamy ajasram asubhan
asurisv eva yonisu
“Those who are envious and mischievous, who are the lowest among men, are cast by Me into the ocean of material existence, into various demoniac species of life.” Thus the destination of godless atheists such as Ravana, Hiranyakasipu, Kamsa and Dantavakra is a hellish condition of life. Mandodari, the wife of Ravana, could understand all this because she was a chaste woman. Although lamenting for the death of her husband, she knew what would happen to his body and soul, for although one cannot see directly with one’s material eyes, one can see with eyes of knowledge (pasyanti jñana-caksusah). In Vedic history there are many instances of how one becomes godless and is condemned by the laws of nature.
