Desireless you cannot be. That is not possible. Desireless means . . . here it is clearly said, sarva-kāmebhyaḥ. Kāmebhyaḥ means desire for sense gratification. That is to be purified. But desire to serve Kṛṣṇa, that is very good, very nice thing. So we have to transfer the desire. This is called Kṛṣṇa consciousness. That's all. Desire we cannot kill. It is not possible. I am a living being. Desire is my constant companion. So therefore Kṛṣṇa consciousness means to purify the desire. How is that? Without sarva-kāmebhyaḥ, without desiring for material sense gratification, I can desire so many things for Kṛṣṇa's service. There are so many things.
And suppose . . . just like take for example eating. Eating, we want palatable dishes. Very good. But you prepare the palatable foodstuff for Kṛṣṇa. For Kṛṣṇa you prepare hundreds of palatable . . . don't think that "It is being prepared for me." Therefore one who prepares foodstuff for Kṛṣṇa, he has to take very precaution, you see, that is being prepared for Kṛṣṇa. Sometimes I therefore ask the students, "Don't touch your mouth. Don't . . . very cleanly, very sanctifiedly." Because it is being prepared . . . so now that desire, that "Kṛṣṇa will eat such nice cake and such nice rice," so the whole thing is prepared in Kṛṣṇa consciousness, and when it is offered to Kṛṣṇa, you taste.
So your kāma is already sacrificed, because from the very beginning you're thinking that, "It is being prepared for Kṛṣṇa." You have no desire for that. But Kṛṣṇa is so merciful that He gives you the foodstuff for your eating; so your desire is already fulfilled. You do not desire it, but Kṛṣṇa's mercy is so that He can fulfill your desire.
