Devotees, they want to give service only. They do not want in exchange from Kṛṣṇa anything. That is pure love. Caitanya Mahāprabhu was teaching like that. Caitanya Mahāprabhu says, na dhanaṁ na janaṁ na sundarīṁ kavitāṁ vā jagad-īśa kāmaye (CC Antya 20.29, Śikṣāṣṭaka 4): "My dear Lord, I do not want from You any amount of riches, dhanam; janam, any number of followers." Na dhanaṁ na janaṁ na sundarīṁ kavitād, "not very nice, beautiful, attractive wife. I do not want all these things."
Because materially we want all these things. All these people are struggling very hard. What for? For riches. "Money, money. Where is money? Where is money?" And then as soon as he has got some money, then he wants to be minister or president or governor. Janam, followers, there will be so many followers. Na dhanam, na janam. And very beautiful wife or husband for sense gratification. These things are wanted for materially ambitious people.
But Caitanya Mahāprabhu says: "I don't want all these things." He's teaching, na dhanaṁ na janaṁ na sundarīṁ kavitāṁ vā jagad-īśa kāmaye. Then what You want? Mama janmani janmanīśvare bhavatād bhaktir ahaitukī tvayi (CC Antya 20.29, Śikṣāṣṭaka 4): "I simply want that I may take my birth anywhere, it doesn't matter, but let me become Your servant. Let me become Your devotee." That is the aspiration of pure devotee.
So as soon as we shall require any material things, the Kṛṣṇa will give us opportunity. But that is not very good proposal. In the material life, either you are very rich man or demigod, or in the higher planetary system, or as insect or any royal person, anywhere, the threefold miseries of material existence there must be. Therefore intelligent man should be aspiring for Kṛṣṇa only and should be satisfied as Kṛṣṇa likes him to do. That's all. This is Kṛṣṇa consciousness movement. You try to understand. Take to it. You'll be happy. That is our propaganda.
