Indian man: Kṛṣṇa . . . in the Gītā it says the student comes to the teacher.
Prabhupāda: If it is natural, then why it was needed that Kṛṣṇa would teach Arjuna? It is not natural. You have to select, by getting knowledge from superior person. Otherwise there is no meaning of teaching, Kṛṣṇa's to Arjuna. Arjuna was perplexed. He was . . . he could not understand whether he should fight or not. So that is the position of everyone. Everyone is perplexed. He requires a guidance like Kṛṣṇa. Then you can find out the . . .
It is not natural. Natural means up to the animal life it is natural. Then come to the human form of life. Then it is discretion. As you like, you make your choice. If you like Kṛṣṇa, you can go to Kṛṣṇa. If you like something else, you can go there. That is your discretion. Everyone has got independence, little independence. Kṛṣṇa says at the end of Bhagavad-gītā, sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja (BG 18.66). "Just you surrender unto Me, giving up everything." If it is natural, then why should He say, "You should do this"? It is not natural. One has to learn it. Therefore he requires a spiritual master like Kṛṣṇa or His representative. But he has got the potency to accept it. And because he has got little independence, he can reject it.
So it is not natural evolution. You have to accept the principle as it is stated in the Bhagavad-gītā. Why it is said, yadā yadā hi dharmasya glānir bhavati bhārata (BG 4.7). If it is actually evolutionary, then why there is dharmasya glānir? Tadātmānaṁ sṛjāmy aham: "As soon as there is discrepancies in the discharge of real duties, I appear." So it is natural. If we keep ourself in natural life, it is natural. But because we are developed consciousness, we do not keep in natural life. We accept so many unnatural things. Therefore our knowledge becomes covered by unnatural material nature.
