So in the material world there cannot be prema. Prema means love. It is only possible in the spiritual world. Here, what is going on in the name as love is not true. What is lust? Atmendriya-priti, to satisfy one’s own senses. That is kama. Here, a boy and girl say “love,” but it is not love. The boy wants to satisfy his senses, and the girl wants to satisfy her senses. That’s all. Therefore, everyone is trying to satisfy her own senses. That is kama. Lust.
What is prema? Krishnendriya-priti-iccha dhare prema nama. When the same propensity is transferred for satisfying Krishna’s or God’s senses, That is Love,Prema.
And real love means to give service to the beloved.
