You fix up your mind at the lotus feet of Kṛṣṇa, then non-Kṛṣṇa desires will be finished. Sa vai manaḥ kṛṣṇa. Everything will be there: the hands will be there, the legs will be there, the eyes will be there, the ears will be there—everything will be there. But if you change your desire, they will be purified. It is not to make it null and void. No. The hand is there, but if you engage your hand in cleansing the temple, then you are transcendental. If your. . . If you walk to go to the temple, then your desire for walking will be spiritual. If you smell the flower offered to the Deity, then your desire for smelling so many scented things will be finished. If you eat prasādam, then your desire for going to the restaurant and making satisfied. . . satisfaction of the tongue will be finished. Therefore if we simply desire eating, sleeping, mating—everything, even mating also. . . If you desire that "If I can beget a child who will be Kṛṣṇa conscious," then you have sex life. Otherwise stop it. If you take this responsibility that you will beget a child who will be Kṛṣṇa conscious, you can produce thousands of children, allowed; otherwise don't become mother and father. This is śāstra. Don't become. Pitā na sa syāj jananī na sā syāt na mocayed yaḥ samupeta (SB 5.5.18). Why? That is the duty. Make your children Kṛṣṇa conscious, then your duty is all right. Otherwise, don't become father and mother.
So desireless means when we don't desire anything material—simply desire to serve Kṛṣṇa—that is desirelessness. Sarvopādhi-vinirmuktam (CC Madhya 19.170). Then it is nirmala, purified. And the. . . what is the function of the purified senses? Hṛṣīkena hṛṣīkeśa sevanaṁ bhaktir ucyate. When your. . . there is no more material desires, none of your senses are engaged in anything except in Kṛṣṇa's service, this is purification. And in that purified state, when your senses are purified by this way, then you can render service to Kṛṣṇa. That service is accepted.
