So for to know Kṛṣṇa, there are so many Vedic literatures. So we have to know through the mercy of the spiritual master. Tad-vijñānārthaṁ sa gurum eva abhigacchet [MU 1.2.12]. Everything is there, just like Kṛṣṇa is there in the Bhagavad-gītā, but people could not understand Kṛṣṇa. Now we are presenting Kṛṣṇa as it is. People are understanding. They are becoming devotee. So we have to go through the right channel. Then we'll know Kṛṣṇa. And as soon as you know Kṛṣṇa as He is, your life is successful. That is the aim and object of Kṛṣṇa consciousness movement—simply to help the people to know Kṛṣṇa. This is the only business, because as soon as you know Kṛṣṇa, your life is successful in which way, eh? The success is tyaktvā dehaṁ punar janma naiti [Bg. 4.9]. This is success. This body should be the last acceptance of material body. That is success. Otherwise, if you continue, tathā dehāntara-prāptiḥ... [Bg. 2.13]. These foolish people, they do not know that dehāntara, there is change of body.
Change of body is there already. You are experiencing, but they do not believe that after death there is body. Why not? If you have got experience in the life—"I have passed through so many changes of body, from babyhood to childhood, childhood to boyhood, boyhood to youth-hood, then middle age and old body"—then what is next? Why do you finish here? It is common logic. Why should you finish here? There must be body. This is real reasoning. And Kṛṣṇa confirms it. Not only your contemplation. Kṛṣṇa says, tathā dehāntara-prāptiḥ: [Bg. 2.13] "In this way you'll have another body." The Kṛṣṇa, the great authority, He says, from whom Brahmā, the first creature, he learned. Tene brahma hṛdā ādi-kavaye. Kṛṣṇa, Vāsudeva... Oṁ namo bhagavate vāsudevāya. He... Tene brahma hṛdā ādi-kavaye. He taught this Vedic literature to the heart of Brahmā. He can teach you through the heart also because He is sitting there. Īśvaraḥ sarva-bhūtānāṁ hṛd-deśe [Bg. 18.61].
