Worship and rendering service, they are different. Worship means there is some motive. I worship some friend or some big man, I have got some motive that, "This big man is a very big businessman, and if I can please him then he may give me some business, I'll derive some profit." So the worship of demigods is like that. They worship different demigods for some particular purpose. That is condemned in the
Bhagavad-gītā, you'll find it in the Eighth Chapter. Kāmais tais tair hṛta-jñānāḥ prapadyante 'nya devatāḥ (BG 7.20). Those who have lost their sense, bewildered by lust, they go to worship demigods with a motive.
So when we speak of worship, there is motive. But when we speak of service, there is no motive. Service is love. Just like mother renders service to the child. There is no motive; it is love only. Everyone can neglect that child; that mother cannot, because there is love. Similarly, bhaj-dhātu, where there is question of service, there is no question of motive. That is perfection of Kṛṣṇa consciousness.
And that is recommended in the Śrīmad-Bhāgavatam, first-class religious principle. What is that? Sa vai puṁsāṁ paro dharmo yato bhaktir adhokṣaje (SB 1.2.6).
This bhakti, this bhaja, the same root, that system of religious principle is first-class. What is that? Yato bhaktir adhokṣaje: by performing which one can develop his God consciousness, or love of God. That's all. If you can develop your love of God—you follow any religious principle, doesn't matter—but you must . . . but the test is how much you are developing your love for God.
But if you have got some motive that, "By practicing this system of religious system, my material necessities will be fulfilled," that is not first-class religion. That is third-class religion. The first-class religion is that by which you can develop your love of Godhead, ahaituky apratihatā, without any cause and without any impediment. That is first class.
So that is being recommended. This yoga system, Kṛṣṇa consciousness, even you take it from religious side, this is first class—because there is no motive. They are not serving Kṛṣṇa to supply them this or that. No. There may be this or that; that doesn't matter. They are engaged in. But there is no scarcity of this and that. They get everything. Don't think that becoming Kṛṣṇa conscious one becomes poor. No. If Kṛṣṇa is there, everything is there, because Kṛṣṇa is everything. So . . . but we should not make any business with Kṛṣṇa, "Kṛṣṇa give me this, give me that."
Kṛṣṇa knows better than you. Just like a child does not demand from the parents, "My dear father, my dear mother, give me this" or "give me that." The father knows what is the necessity of the child. So this is not very good business to ask God, "Give me this, give me that." Why shall I ask? If God is all-powerful, He knows my wants, He knows my necessities, and that is also confirmed in the Vedas, eko bahūnāṁ vidadhāti kāmān (Kaṭha Upaniṣad 2.2.13):
That single one God is supplying all necessities of millions and trillions, and innumerable—there is no count, living entities.
So we should simply try to love God, not demand anything. Demand is already supplied. Even the cats and dogs are getting their necessities. They don't go to the church or ask anything from God, but they are getting. So why a devotee shall not get? If a cat and dog can get his necessities of life without demanding from God, why shall I demand from God that, "Give me this, give me that." No. We shall simply try to love Him. That will fulfill everything. That is called highest platform of yoga.
