Chanting Hare Krishna is the only proven method to cleanse the mind and conquer material illusion.Listen — Srila Prabhupada Uvaca
Bhagavad-gītā 2.26 — December 6, 1968, Los Angeles 681206BG-LOS ANGELES [47:39 Minutes] Prabhupāda: [indistinct] ...these living symptoms develop. The anthropology, Darwin's theory. They do not believe in soul, transmigration of the soul. They have their own theory.
But they are also not definite. Those who have read Darwin's theory of anthropology, in most places that Mr. Darwin says, "Perhaps it was like this, perhaps it was like this." And according to his theory, there was no existence of human being ten thousand years ago. But we followers of Vedic... [child making noises] You have to stop. ...version, we don't believe to all this nonsense; neither there is any basic principle. Now take for example the atheistic theory—call it by any name—that combination of matter makes a living symptom possible.
So scientific, I mean to say, proposition is based on observation and experiment. So this is simply observation, that those who are atheistic person... Just like medical science: There are many doctors. They are observing when a man dies, observing, feeling the pulse, taking pulse beating, offering oxygen gas, trying to save him. All of a sudden the man dies—and he is sure to die—but they cannot simply observe the symptoms.
They cannot observe what is that thing which is gone now. They cannot say that. Neither it is possible for them to say. But their theory that combination of matter makes symptoms of life possible, they should prove it by experiment.
Then it is complete science. Observation and experiment. But there is no such experiment till now. You trace out the history of the human society... Of course, in the modern world they cannot trace out chronological history more than three thousand years.
That's all. But we can give account for many millions and millions of years. Just like in the Bhagavad-gītā Kṛṣṇa says, imaṁ vivasvate yogaṁ proktavān aham avyayam [Bg. 4.1]: [The Blessed Lord said: I instructed this imperishable science of yoga to the sun-god, Vivasvān, and Vivasvān instructed it to Manu, the father of mankind, and Manu in turn instructed it to Ikṣvāku.] "I spoke this philosophy of Bhagavad-gītā to the sun-god." Now just imagine how many years, millions of years. So the modern theory that ten thousand years ago there was no human civilization, how we can adjust things? The Battle of Kurukṣetra was fought five thousand years ago.
Before that, hundreds of thousands year ago there was another battle, which is called fight between Rāma and Rāvaṇa. And there are so many instances in the Vedic literature. We can offer history of the world, of the universe, from millions and millions of years ago. But these people with petty knowledge for three thousand years or four thousand years, they are thinking they have advanced. So this theory was current in those days also; otherwise why Kṛṣṇa is making reference to this theory? So all kinds of theories are existent since the beginning of this creation.
