You have seen the picture of Kṛṣṇa. You will never see Kṛṣṇa as old man. When Kṛṣṇa was in the Battlefield of Kurukṣetra . . . you have seen the picture: Kṛṣṇa is driving the chariot of Arjuna. At that time His age was not less than hundred years. He had great-grandchildren. But you have seen the picture. He was looking like a boy of sixteen to twenty years. Therefore Kṛṣṇa is described in the Vedic literatures as nava-yauvanaṁ ca. Kṛṣṇa's body . . . therefore His body is spiritual body. The spiritual . . . when you get your spiritual body, you also get nava-yauvanam. Those who are associating with Kṛṣṇa in the Kṛṣṇa planet or those who are associating with Nārāyaṇa in the Vaikuṇṭha planets, they are also ever-young. Their bodily features are exactly like Nārāyaṇa. It is called sārūpya-mukti.
So this Kṛṣṇa consciousness movement is a great science of understanding what is God. Simply with vague idea, "There is God," that is not sufficient. That is good, simply to understand, "There is God." Generally, they do not believe that there is God. But if somebody says: "Yes, there is God, but I have no business with Him," no. You should know God, actually what is His name, what does He do, where is His residence, what is His business. You should know this. And these things are possible to understand in this human form of life.
We go to the human society to speak of Kṛṣṇa consciousness. We do not go to the society of animals, because they have no capacity to understand. Their body does not permit to understand what is God. But the human society . . . it doesn't matter whether he is born in India or Czechoslovakia or Russia. I have been in Russia also. It is not that, that they are godless. The population is as good as in other country, but the government is suppressing. So that is another chapter.
