Prabhupada: Yes. Kṛṣṇa can be served by his own occupation, as I described just now. Or whatever you may be. You may be a potter, you may be a florist, you may be... Whatever you may be, but you can satisfy Kṛṣṇa by his work, by your work. You do not require to qualify yourself with some specific qualification. Whatever qualification you have got, you have to dovetail it under the direction of expert spiritual master, how you can serve. That's all.
Devotee: What does that expert mean in the list of qualifications for a devotee? In the list of qualifications of a devotee there is one qualification, expert.
Devotee: What does that mean in relation to the occupation?
Prabhupada: Expert means whatever he is doing, he must do it very nicely That's all. Suppose you are sweeping this room. You can do it very nicely, to your best knowledge. That is expert. The people will say, "Oh, you have very nicely done." Any work you do, do it very nicely. That is expert. Don't do it haphazardly. To your best talent, to your best capacity, try to finish it very nicely, whatever it may be. You are entrusted with some work. Do it nicely. That is expert. If you think that you are unable to do that work, then whatever work you can do, you take. But do it nicely. That is expert. Don't imitate. "Oh, I have no capacity to work in that way, but I want to imitate. Oh, he is doing that. I shall do that." Don't do that. That is not expert. You take up what you can do very nicely and do it nicely. We have so many works. Kṛṣṇa is not that He is static. He is dynamic force. Just like Arjuna, he was not a Vedantist, he was not a brāhmaṇa, he was not a sannyāsī. He was householder. He was military man. But he knew his business, how to do it nicely. So you do your business nicely. That is expert. And when it is dovetailed in Kṛṣṇa, there is no gradation that this business is better and that business is lower because everything is for Kṛṣṇa. So that business becomes Kṛṣṇa. Do it nicely and Kṛṣṇa is satisfied. And that is your success...
Expertness is you just try to do which is easily performed by you. You don't accept anything heavy task because Kṛṣṇa does not want that you have to do this heavy task. Whatever you know, you just apply it. You dovetail it in Kṛṣṇa consciousness. Kṛṣṇa does not say that you have to become like this, like that, like that, then you can serve Him. Does not say. Just like this cow. Just see. What does it know? He's an animal. You see? But the calf knows to brush his head and tongue like this, in love. It is doing and Kṛṣṇa accepting, "Yes." That is expert. First of all find out what is easily done by you. Don't take anything which is not easily done by you. You find out what is your occupation, what you can very nicely and easily perform, and do it for Kṛṣṇa. That's all. Is that clear? Expert? This is expert. Expert does not mean that I do not know how to drive motor car, and I will have to imitate somebody, "Oh, I shall become driver." Why? If you do not know driving, why should you attempt driving? Whatever you know, you just try it, that business, and try to satisfy Kṛṣṇa. If you know driving, that's all right. But don't take...
My Guru Mahārāja explained that you haven't got to learn anything extra for Kṛṣṇa's service. Whatever you know, you just apply it... Then you become successful. Because our time is very short. We do not know when I am going to die. As soon as I am out of this body, I am completely under the grip of nature, and I do not know what kind of body I am getting next. Of course, Kṛṣṇa assures that His devotee will never be vanquished. He will get good body. But I do not know what kind of body I am going to... Therefore before finishing this body I will have to develop Kṛṣṇa consciousness very nicely. That is my success.
