"There may be thousands of beautiful women before a devotee, but that does not disturb his mind. He sees they're all energies of Kṛṣṇa. 'They are gopīs of Kṛṣṇa. They are enjoyable by Kṛṣṇa. I have to serve them. They're gopīs. Because I am servant of the servant.' Gopī-bhartuḥ pada-kamalayoḥ dāsa-dāsa-dāsānudāsaḥ (CC Madhya 13.80). So a devotee should try to engage all beautiful women in the service of Kṛṣṇa. That is his duty. Not to enjoy them. That is sense gratification.
This is the position of a devotee. He's not pierced by the arrows of Cupid, but he sees everything, nirbandhe kṛṣṇa-sambandhe. He sees everything in relationship with Kṛṣṇa. Yukta-vairāgyam ucyate. That is vairāgya. He does not accept anything for his sense gratification, but he engages everyone in the service of Kṛṣṇa. Then we can get out of the influence of the arrow of Cupid. This is the process."
