Now, Lord Śrī Kṛṣṇa says that "Just like if you have got a very good ship, you can very easily cross the Atlantic Ocean without any difficulty, similarly, we are in the midst of the ocean of ignorance." Our, this life, this conditioned life in the material world is just like the ocean of ignorance, ocean of ignorance. So Lord Caitanya, therefore, He prayed to Śrī Kṛṣṇa like this, ayi nanda-tanuja patitaṁ kiṅkaraṁ māṁ viṣame bhavāmbudhau: "My dear Lord Kṛṣṇa, I am just fallen in the ocean of ignorance." So we are in the ocean of ignorance. Now, in the ocean, if you get a very good boat or very good ship, as you can cross over, similarly, if we have the ship or the boat of perfect knowledge, then there is no fear. We can cross the ocean very easily. We can cross this ocean very easily.
(Lecture on Bhagavad-Gita-------4:34-38 by Srila Prabhupada).

Now here Kṛṣṇa says, api ced asi pāpebhyaḥ sarvebhyaḥ pāpa-kṛttamaḥ. If, if a person is the most sinful, the, and the, I mean, the supermost sinful man, but if he gets this knowledge, this knowledge of Kṛṣṇa science, then he can cross over this ocean of ignorance very easily. That means it does not matter what was our past life. Either... Any Vedic literature, especially Bhagavad-gītā... Bhagavad-gītā does not take into account what was you in the past life. That doesn't matter. Because we are in ignorance, we might have done so many things in ignorance, which is not approved, which is not virtuous. That is quite possible. Every one of us, we are subjected. Because due to ignorance, we do so many things, so nobody can say that "I am free from any sinful activities." Nobody can say. So that doesn't matter. But if we get, if we can learn the science of Kṛṣṇa, then, Lord Śrī Kṛṣṇa says, api ced asi pāpebhyaḥ sarvebhyaḥ pāpa-kṛttamaḥ: "Even one is the most sinful man, but if he gets the Kṛṣṇa science, he is free. He is free, and he can go. He can cross over the material ocean of ignorance very easily."
(Lecture on Bhagavad-Gita-------4:34-38 by Srila Prabhupada ).

So by culture of Kṛṣṇa science, when we understand the Kṛṣṇa science, then we become free from this ignorance. And Lord Kṛṣṇa recommends that "By this knowledge, you can very easily cross over the ocean of nescience, ocean of ignorance." The whole thing is: we are suffering due to... Just like ignorance is no excuse in the law court. Suppose you have done something wrong and if you say to the judge, "So I, I did not know, sir, this law," oh, that is no excuse. You'll be punished. You'll be punished. Now, in the śāstra, in the Vedic literature, it is said that "Everything belongs to God. Everything is manufactured by God. So everyone has right, not only human being, even the animals, everyone has got the right to live and use things as much as he requires. But if he stocks more, if he acquires more, he becomes the thief, and he is punishable." Now, suppose if I say, "Oh, I do not know this law. Therefore I have accumulated so much things in my control," oh, that does not mean that you'll not be punished. You'll be punished. You'll be punishable. This knowledge we require to know. And people at the modern age, they are lacking this knowledge.
(Lecture on Bhagavad-Gita-------4:34-38 by Srila Prabhupada ).

So the meaning of this verse is that... Bhavāmbudhiḥ. Bhavāmbudhiḥ means this material nescience, ocean of nescience. It is a ocean of ignorance, nescience. This is called bhavāmbudhiḥ. But one has to cross over this nescience, ocean of nescience. And how to cross over? Now, samāśritaṁ pada-pallavam. One who has taken shelter of the lotus feet as the boat for crossing over this ocean of nescience, for him, bhavāmbudhiḥ, this great ocean, becomes vatsa-padam.
(Lecture on Bhagavad-Gita-------7:3 by Srila Prabhupada ).

They are struggling for freedom. What is this nonsense, freedom? You are under the grip of the material nature. Where is your freedom? Now you have got, nature has given you this human form of body. Next you may get another body, next you may... That is completely under the control of material nature. So they do not know. They do not know, completely in darkness. Tamo 'ndham. Therefore those who are eager to cross over the ocean of ignorance, for them, these instructions are there. Nārāyaṇaṁ namaskṛtya naraṁ caiva narottamam [SB 1.2.4]. You have to go in the paramparā system, submission, tapasya, jñāna. Bahavo jñāna-tapasā pūtā mad-bhāvam āgatāḥ. So by jñāna, by knowledge, by tapasya, you have to make progress. This is Kṛṣṇa consciousness movement.
(Lecture on Srimad Bhagavatam------1:2:4 by Srila Prabhupada ).

So be careful that this material world is itself dangerous. Especially in this age of Kali, it is dangerous. It is stated in the śāstra, padaṁ padaṁ yad vipadām [SB 10.14.58], every step there is danger. This is the position. Māyā is so strong that you should always expect simply danger. But if you become Kṛṣṇa conscious, you can overcome these dangers... Padaṁ padaṁ yad vipadāṁ na teṣām. It is not... This dangerous position is not for them. Who? Samāśritā ye pada-pallava-plavam, one who has taken shelter of the lotus feet. It is a great ocean, just like the Pacific Ocean. It is just like a great ocean, big ocean of ignorance. As in the ocean, if you go, even on a boat, it is always dangerous, similarly, we are in the ocean of material civilization. There is always danger. But if you take shelter of the lotus feet of Kṛṣṇa, paraṁ padam, then you overcome the danger and you go back to home, back to Godhead.
(Lecture on Srimad Bhagavatam------1:16:24 by Srila Prabhupada ).

Really, originally, the, I mean to say regulator of religious principle is the Supreme Personality of Godhead. Therefore Kṛṣṇa is sometimes addressed as dharma-setu. Setu means bridge. We have to cross over. The whole plan is that we have to cross over the ocean of nescience in which we are now fallen. The material existence means it is ocean of ignorance and nescience, and one has to cross over it. Then he gets the real life. This is not real life. Bhūtvā bhūtvā pralīyate [Bg. 8.19]. We are... Na hanyate hanyamāne śarīre [Bg. 2.20]. People are so foolish. They do not take it very seriously because they do not know that they are eternal. That is another ignorance. Bhagavad-gītā begins from this knowledge that living soul is eternal, na hanyate hanyamāne śarīre [Bg. 2.20]. But they are in ignorance.
