Love is to repose all affection in one object and there is no living creature on earth that we can repose all our affection in. It will always be divided. Only Krishna has the power to attract and to accept all the affection of a living being. Because the soul has eternal love that is simply longing and dying to be expressed and directed towards someone. But we cannot express or offer all our eternal love to some temporary form or object or person of this world. Only Krishna can reciprocate that love. Therefore to love means to love God and without love of God, in the true sense there is no love at all. What goes in the name of love in this world is a type of mutual exploitation tinged with selfishness. It is affection but it is not love. sa vai puḿsāḿ paro dharmo yato bhaktir adhokṣaje ahaituky apratihatā yayātmā uprasīdati. The supreme occupation [dharma] for all humanity is that by which men can attain to loving devotional service unto the transcendent Lord. Such devotional service must be unmotivated and uninterrupted to completely satisfy the self. That is the goal of life. Love of God is the Supreme goal, the perfection of life. It is the purushartha siromani. Of all the goals of life, of all the attainments, it is the crest jewel, it is the highest, and it is the only level of consciousness that completely satisfies the heart.
