So in the material world there cannot be prema. Prema means love. The prema is only possible in the spiritual world. Here, what is going on as love, that is not love, that is lust. A boy loves a girl, a girl loves a boy—that is not love, that is lust. As soon as there is some disturbance in lusty affair, they divorce. So therefore that is not love. So we should note it, that so-called love is bogus in this material world. Love cannot be possible. This very word, love, prema, is specially reserved for Kṛṣṇa. Premā pum-artho mahān (Caitanya-manjusa). That is Caitanya Mahāprabhu's preaching, that the highest perfection of life is to evoke one's dormant love for Kṛṣṇa.
The love is there. It is reserved for Kṛṣṇa. But due to our foolishness, we are distributing that love in so many ways, up to the dog. This is called illusion. We do not know where to apply love. In this way . . . all these words is touched with the word kāma. Kāma. Kāma means lust. There is no question of love. And love . . . prema and kāma is described in Caitanya-caritāmṛta, what is prema and what is . . . prema and kāma. Ātmendriya-prīti-vāñchā tāra bali kāma (CC Adi 4.165). Kāma. What is lust? Ātmendriya-prīti, to satisfy one's own senses. That is kāma. Here, a boy and girl love. They say "love," but no, it is not love. The boy wants to satisfy his senses, and the girl wants to satisfy her senses. That's all. Therefore, ātmendriya-prīti-vāñchā. Everyone is trying to satisfy her own senses. That is kāma, lust. And then, what is prema? Kṛṣṇendriya-prīti-icchā dhare prema nāma, that when the same propensity is transferred for satisfying Kṛṣṇa's senses.
