Regarding your questions, the so-called love which goes on in the material world is simply a perverted form of dasya rasa. Everything in this world is a perverted form of rasa. Just like Yasoda is loving Krishna as her Son. So this is vatsalya rasa, parental love. When Krishna is separate from Yasoda, she cried for whole life and thus became blind. In this world there is not a single instance where a mother has suffered so much in separation from her son. Therefore, it is perverted reflection of the real love.
Letter to Mahapurusa, 25 January, 1969
