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. That is stated in Bhagavad-gītā:
- brahma-bhūtaḥ prasannātmā
- na śocati na kāṅkṣati
- samaḥ sarveṣu bhūteṣu
- mad-bhaktiṁ labhate parām
- (BG 18.54)
This is the sign of liberation. A man who is liberated, his signs are explained in the Bhagavad-gītā, brahma-bhūtaḥ prasannātmā. His first symptom is that he's very happy. One who is liberated, his first symptom is that you'll never find him morose. He is happy. Prasannātmā. Na śocati na kāṅkṣati. He has no anxiety. "Oh, this thing I haven't got. I have to secure this thing. This bill I have to pay. Oh, this I am to do." So many anxieties. We are full of anxieties. So he has no anxieties.
