Lord Krishna states in Bhagavad-gita, ye yatha mam prapadyante tams tathaiva bhajamy aham: [Bg. 4.11] "As people approach Me, I reciprocate with them accordingly." Yet even if the Lord is approached by someone with devotion, to intensify the devotee's love the Lord may not immediately reciprocate fully. In fact, the Lord is truly reciprocating. After all, a sincere devotee always prays to the Lord, "Please help me to love You purely." Therefore the Lord's so-called neglect is actually the fulfillment of the devotee's prayer. Lord Krishna intensifies our love for Him by apparently separating Himself from us, and the result is that we achieve what we really wanted and prayed for: intense love for the Absolute Truth, Krishna. Thus Lord Krishna's apparent negligence is actually His thoughtful reciprocation and the fulfillment of our deepest and purest desire.
According to the acaryas, as Lord Krishna began to speak this verse the gopis looked at one another with squinting eyes, trying to hide the smiles breaking out on their faces. Even as Lord Krishna was speaking, the gopis had begun to realize that He was bringing them to the highest perfection of loving service.
