We don't say that you kill your desire. No. You purify your desire to satisfy Krsna. That's all. Now your desire is to satisfy your senses. That's all. This has to be purified, that you shall desire, but you shall desire to satisfy Krsna. Then your perfection is there.
In one way it is very simple and easy because I know how to satisfy my senses. I am doing it life after life. The same endeavor should be engaged for satisfying Krsna. That's all. The process has not to be learned by me. I know it. Simply account has to be changed. That's all. So Krsna consciousness is very simple and easy. Immediately you come to the spiritual platform, or transcendental platform.
That is explained in the Caitanya-caritamrta: lust and love, what is the difference between lust and love. In the material world there is no love. Because everyone is directed by lust. The so-called love... A young boy is trying to love a young girl, or young girl is trying to love a young..., but the background is lust. There is no love. It is simply a show of love. Therefore, after satisfying lust, there is divorce, there is separation. So in the material world there is no possibility of love. It is all lust. Love is only possible when you love God. There is no lust. There is no question of sense gratification. Simply for love: "Krsna is my lover. Krsna is my master. Krsna is my friend."
Just like Arjuna. Arjuna is loving Krsna as friend. So he is so great lover that in the beginning he hesitated to fight, "How shall I kill my kinsmen?" But when he understood, "Krsna, my friend, desires. Oh, never mind." So there was no lust. Simply love of Krsna. So lust and love, that means the same thing is there. Simply one has to change the account. That's all. Lusty people, they are working on account of sense gratification, and lover of Krsna is working for Krsna's satisfaction. The activity may appear superficially the same.
