You create something, you create some medicine that, "Take this tablet and no death, no more. At least no disease." That is not possible. There is disease, development of different kinds of disease, and they are discovering different kinds of medicine. That is a struggle. That is not scientific improvement. There is one problem before you, and you are creating some antidote. That's all. This is struggle, struggle for existence. This is not scientific advancement.
But how one can be stopped from repetition of birth and death? That is here in the Bhagavad-gītā. What is that? Kṛṣṇa says, janma karma me divyaṁ yo jānāti tattvataḥ (BG 4.9). You try to understand Kṛṣṇa only, what is Kṛṣṇa. Janma karma . . . yo jānāti tattvataḥ: anyone who knows in truth, not superficially: "Oh, Kṛṣṇa I know. In the . . . there is a place, they have got an idol of Kṛṣṇa. They are worshiping. I know everything about Kṛṣṇa." Not like that. Try to understand Kṛṣṇa, what He is. He is Kṛṣṇa, undoubtedly, but people want to know actually what is Kṛṣṇa. That we are open.
So if one simply understands what is Kṛṣṇa, the result is tyaktvā dehaṁ punar janma naiti (BG 4.9). Simply by understanding Kṛṣṇa, there is no more taking birth. Punar janma. If you take birth, then there is death. If you stop your birth, then you can stop your death also. Because birth and death is in relationship with this body. If you don't have a material body, then there is no question of birth, death, old age and disease.
So this is the process of Kṛṣṇa consciousness. People should be interested by hearing the words of Kṛṣṇa. That is intelligence. Kṛṣṇa says that, "In this way you can stop your birth and death process." So why don't you do that? Why you are after so many things? If you simply try to understand Kṛṣṇa, and if you perfectly understand, then immediately you can stop your birth and death process. You are eternal. That is intelligence. That is intelligence. Just like Kṛṣṇa says: "After many, many births, one comes to this conclusion that Kṛṣṇa is everything." So why shall I wait for another many births? Why not accept Kṛṣṇa as everything? This is intelligence.
Kṛṣṇa is saying, He's not bluffing. So why not take Kṛṣṇa's word as truth and immediately, mam prapadyate, immediately surrender? "Kṛṣṇa, I do not know anything. I simply surrender unto You. Please protect me." That's all. Finish business. Very simple thing, this Kṛṣṇa consciousness movement. Everyone can take. Doesn't require to become very highly, I mean, scientist, philosopher and something like that. Simply accept Kṛṣṇa's words and see the result. And the result is happening also. Those who are accepting Kṛṣṇa in that way and trying their best to please Kṛṣṇa with this human form of life, how much they are happy, how they are enjoying life.
