Srimad-Bhagavatam: Canto 7 - Chapter 1 - Verse 38

Sanskrit:

ताविहाथ पुनर्जातौ शिशुपालकरूषजौ ।हरौ वैरानुबन्धेन पश्यतस्ते समीयतु: ॥ ३८ ॥

ITRANS:

tāv ihātha punar jātauśiśupāla-karūṣa-jauharau vairānubandhenapaśyatas te samīyatuḥ

Translation:

They both took birth again in human society as Śiśupāla 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:

Vairānubandhena. Acting like the Lord’s enemy is also beneficial for the living entity. Kāmād dveṣād bhayāt snehād. Whether in lusty desire, anger, fear or envy of the Lord, somehow or other, as recommended by Śrīla Rūpa Gosvāmī (tasmāt kenāpy upāyena), 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?
