So our duty, persons who are Kṛṣṇa consciousness, engaged in Kṛṣṇa consciousness, they should always know that everything is to be done by Kṛṣṇa. We cannot do anything without Kṛṣṇa's sanction. But still, we have to do our own duty. Not that, "Oh, Kṛṣṇa will do everything. Therefore we shall not try for a storefront or we shall not go to see this man or... Kṛṣṇa..." No! That is lethargy. You have to do your own duty. But result, depend on Kṛṣṇa. This is Kṛṣṇa conscious. You don't be sorry if there is failure, you don't be unhappy if there is success, uh, you don't be too much, I mean to say, jubilant if there is success. Everything is done by Kṛṣṇa. This is the attitude of Kṛṣṇa consciousness. They have to do their own duty. Never mind whether it is suffering or happiness. It doesn't matter.
Madhudviṣa: "O best among men, the person who is not disturbed by happiness and distress, and is steady in both, is certainly eligible for liberation."
Prabhupāda: Yes. This is the sign, characteristics or symptoms of a person who is going to be liberated in this life. He has to do his duty. So far we are concerned, we have accepted Kṛṣṇa consciousness duty, so we have to execute our duties faithfully and seriously. Then it is sure Kṛṣṇa will give us the desired result. A nice example is given. Just like a girl is married to a boy. Generally, girls desire a child. So if she, after the marriage, if she immediately wants a child, that is not possible. But because she is married, and if she serves faithfully her husband, her husband is pleased and there is love, in due course of time, there will be child. Why there is hesitation? There will be child. Similarly, we have taken to Kṛṣṇa consciousness. If we discharge our duties faithfully, then in due course of time, Kṛṣṇa will give the desired result. Don't be hesitant. Don't be doubtful. It is sure. Kṛṣṇa says that tyaktvā dehaṁ punar janma naiti mām eti kaunteya (BG 4.9). Anyone who is in Kṛṣṇa consciousness perfectly, for him, after leaving this body, he's coming to Me. This is His assurance. So we haven't got any doubt, Kṛṣṇa has assured. So let us do our duty perfectly, as far as possible. We cannot execute anything perfectly in presence of Kṛṣṇa because He is infinite, we are finite. Our energy, our talent, everything is finite. But if we try our best, then bhāva-grāhī-janārdana. Kṛṣṇa sees only how much sincere I am, how much sincerely I'm executing the duties entrusted upon me. That's all. Otherwise it is not in our power to serve Kṛṣṇa perfectly. That is not... Because we are very teeny. But be assured that the desired result will come if we act sincerely to the point. Yes.
Madhudviṣa: "Those who are seers of the truth have concluded that of the nonexistent there is no endurance and of the eternal there is no cessation. Seers have concluded this by studying the nature of both." Purport: "There is no endurance of the changing body. That the body is changing every moment by the actions and reactions of different cells is admitted by modern medical science, and thus growth and old age are taking place. But the spiritual soul exists permanently, remaining the same in all changing circumstances of the body and mind. That is the difference between matter and spirit. By nature the body is ever-changing and the soul is eternal. This conclusion is established by all classes of seers of the truth, impersonalists and personalists."
Prabhupāda: This is... So far the constitution of the spirit is concerned, it is eternal. That is accepted by all philosophers, personalists and impersonalists. The only difference is that the impersonalist says that after liberation, after getting freed from this bodily contamination, the spirit soul mixes with the Supreme Soul, all-pervading, without any individual existence. Just like the same example, that the small sky within the pitcher. When the pitcher is broken, the small sky within the pitcher mixes with the big sky. The Vaiṣṇava philosopher says that the small sky is individual. It mixes with the big sky, but it keeps its individuality. The example is given in this connection: just like a green bird entering a green tree. So when the bird enters the tree, nobody can find out where is the bird because the leaves of the tree are green and the bird is also green. Nobody can trace out. But that does not mean the bird has lost its individuality. The individuality is there. Just like you see one airplane is flying in the air, and when it goes too far, it appears that it has disappeared. It seems to us that there is no more that airplane. It has mixed with the sky. But actually it is not. It is still there, individual existence. It is my ignorance that I see that it is no more separate, it has mixed with the sky. Just like in the daytime we don't find any star in the sky. Due to the dazzling sunshine, we cannot see any stars. At night, we can see millions of stars, there are. Similarly, that is the impersonalism and personalism. One whose knowledge is not perfect, they think imperson, everything homogeneous. And one whose knowledge is perfect... Vedas also confirm it... Just like in the Īśopaniṣad, there is a verse in which it is stated that "Please withdraw Your effulgence so that I can see Your real face." Just like the sun globe. You cannot see it perfectly due to the dazzling sunshine. But the sun globe is there, and in the glow there are living entities, and there is a principal head man, god. They are not man because their body is made of fire. So similarly, the first, impersonal impression, Brahman, then further advanced, Supersoul, and when further advanced, the Supreme Personality of Godhead, Kṛṣṇa. Brahmeti paramātmeti bhagavān iti śabdyate (SB 1.2.11). First realization, Brahman, impersonal; the second realization is Paramātmā, Supersoul; and the last realization is the personal form of God, Kṛṣṇa.
