Srimad Bhagavatam Canto 07, Chapter 10, Text 38

SB 7.10.38

tav ihatha punar jatau
 sisupala-karusa-jau
harau vairanubandhena
 pasyatas te samiyatuh
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
They both took birth again in human society as Sisupala and Dantavakra and continued in the same enmity toward the Lord. It is they who merged into the body of the Lord in your presence.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Vairanubandhena. Acting like the Lord’s enemy is also beneficial for the living entity. Kamad dvesad bhayat snehad. Whether in lusty desire, anger, fear or envy of the Lord, somehow or other, as recommended by Srila Rupa Gosvami (tasmat kenapy upayena), one should become attached to the Supreme Personality of Godhead and ultimately achieve the goal of returning home, back to Godhead. What, then, is to be said of one who is related to the Supreme Personality of Godhead as a servant, friend, father, mother or conjugal lover?
