So this knowledge is . . . just see how He's making analytical study of the living entities. Beginning from eighty-eight, er, eight hundred . . . 8,400's millions species of life, He's selecting only few human civilized life—then addicted to the, I mean to say, certain kind of faith; then extracting them who are actually believing; and then those who are actually believing. Out of them, those who are sacrificing, making charities and adopting penances, out of many millions of like, persons like that, some of them are actually in knowledge what he is. You'll find in your country also. There are many foundations, they are making charities. But hardly you'll find amongst them that he knows that what he is.
So out of many millions of these religious person, some of them know what he is, "I am not this body." Now, simply theoretically knowing that "I am not this body, I am spirit soul," that is not perfect. You have to actually become liberated from the material entanglement. That is called mukti, liberation. So out of many thousands of persons who are in the knowledge what they are or what he is, some of them are actually liberated. Liberated. And out of many thousands of people who are liberated, they can understand what is Kṛṣṇa.
So Kṛṣṇa understanding is not very easy job. But Kṛṣṇa is so kind, because He knows that in this age, in this age of Kali, it will be very difficult for person to become liberated under the process—first to become civilized, then to become religious, then to perform this charity, sacrifices, then come to the platform of knowledge—then, after coming to the platform of knowledge, you come to the platform of liberation, and after being liberated, you can know what is Kṛṣṇa.
