Love is divine. But love is expressed differently and in different degrees according to the evolution of the individual soul.
There are people who still have hatred, jealousy, anger and pride in their hearts. To such, God is above, beyond and apart. They also may love God, but their love is selfish. This love is tamasic.
That, too, is a low form of love which people love and worship God as a separate being, and pray to him for the fulfillment of their material desires. Such love is known as rajasic love.
But when the love, the lover and the beloved have become one, when we see God and love him as the innermost Self of all beings; and when there is a continuous current of love flowing in the heart, then is it that we realize divine love.
When such divine love fills the heart, we transcend the three gunas and become united with Brahman.
