Sri Caitanya Mahaprabhu gave Srila Rupa Gosvami that drop of the endless ocean of nectar, bhakti-rasa.
If we can serve the gopis, and especially Radhika, we can also have love and affection for Krsna, and then we can feel separation. Otherwise, it will never be possible. Caitanya Mahaprabhu, the Six Gosvamis, Srimad- Bhagavatam, and Sukadeva Gosvami have proclaimed this conclusion: our goal is krsna-prema.
