There are kings who were liberated through hatred, Through animosity the kings like Shishupala, Paundra, Salva and others imitating His special gait, enjoyment, look and even thinking ever in their sleep as well as in their normal life attained nearness to the Lord. Then, is it necessary to restate that those who are particularly attracted towards the Lord will surely be liberated? This is only for the purpose of eulogizing the Lord's compassion for those devotees who out of devotion have constant remembrance. For His devotee, even though due to the power of curses they have animosity, the Lord gives the fruits of devotion.
Shishupala and others were the earlier devotees in this manner. They were full of hatred due to the power of curses. Therefore, by mentioning previous incidents the despisers of the Lord are liberated, thus is explained. Otherwise, why would there be reference to such unconcerned events ? This is to remind that the Lord is equally compassionate to those who despise and detest, taking into consideration their previous deeds of devotion. He assures, “My devotees will never perish”. Would not otherwise statements like remembrance in any manner be contradiction. It is quite natural that those who always cherish hatred will always hate. In which case it would be surmised that those who hate their teachers would also attain the greatness of their teachers.
There is nothing special that since the Lord accepts both the devotees and those who hate, the fruits of their action also will be identical. People like Hiranyakashipu were released from the effect of the hatred towards the Lord because of his son Prahlaada's devotion to the Lord. Beginning with “I, the one who has been insulted” to “Therefore, pardon my father from departing to the world of darkness”, thus Prahlaada having prayed for Lord's Grace.
