Though all incarnations are Divine, Krishna avatara was special in this sense that He spent all his time smiling and smiling, full of love...This is the main quality of God. God has no trace of ego or pride or jealousy whatsoever. Love has no reason. Love is the basis for love. Only through this love, we can attain God. Any other spiritual pursuits give us the temporary joy and not the permanent bliss. Only through the principle of love and its practice, we can recognize and realize the embodiment of love. Where is this love? This love is within us, but we divert this love in different ways. We have a variety of sweets, but the same sugar is present in all of them. Similarly, the Divine love is inherent and immanent in everybody. There is no human heart in which there is no love. So, we should visualize the love which is in everybody. To teach this path of love, Krishna incarnated.
