This difference has been explained by the author of Caitanya-caritāmṛta, that what is the difference between lusty desires and love? That has been explained.

Lecture on SB 6.1.26 -- Honolulu, May 26, 1976:

When it is Kṛṣṇa-centered, then it is spiritual, and when it is whimsical centered, then it is material. There is no difference between material... This is the difference. There is... Just like lusty desires and love, pure love. What is the difference between lusty desires and pure love? Here we are mixing, man and woman, mixing with lusty desires, and Kṛṣṇa is also mixing with the gopīs. Superficially they look the same thing. Yet what is the difference? So this difference has been explained by the author of Caitanya-caritāmṛta, that what is the difference between lusty desires and love? That has been explained. He has said, ātmendriya-prīti-vāñchā-tāre bali 'kāma' (CC Adi 4.165), "When I want to satisfy my senses, that is kāma." But kṛṣṇendriya-prīti-icchā dhare 'prema' nāma, "And when we want to satisfy the senses of Kṛṣṇa, then it is love, prema." That is the difference. Here in this material world there is no love because the man and woman, they have no idea that "I mix with the man, the man who satisfies desires with me." No. "I will satisfy my desires." This is the basic principle. The man is thinking that "Mixing with this woman, I'll satisfy my sense desire," and woman is thinking that "By mixing with this man, I shall satisfy my desire." Therefore it is very prominent in the Western countries, as soon as there is difficulty in personal sense gratification, immediately divorce. This is the psychological, why so many divorces in this country. The root cause is that "As soon as I don't find satisfaction, then I don't want." That is stated in the Śrīmad-Bhāgavatam: dāṁ-patyaṁ ratim eva hi. In this age, husband and wife means sex satisfaction, personal. There is no question of that "We shall live together; we shall satisfy Kṛṣṇa by being trained up how to satisfy Kṛṣṇa." That is Kṛṣṇa consciousness movement. Don't do anything for your personal sense gratification. Do everything for Kṛṣṇa's sense gratification.
