Bhakti means... When you are advanced in bhakti... Bhaktih paresanubhavo viraktir anyatra syat [SB 11.2.42]. That is the test. The example is... Just like when you are hungry, you are given some food, you are eating voraciously. But when you are satisfied, you'll say, "No more. No more." Similarly, when you get Krsna, then you will say, "No more. No more material necessities."
