Puṣṭa Kṛṣṇa: Can intelligence be created in an unintelligent person?
Prabhupāda: Everyone is intelligent. That I have already explained. Everyone has got brain and intelligence, but he has to use it properly. That is wanted. That is education. You cannot teach a stone how to manufacture this microphone. That is not possible because he has no intelligence. But even one is dull brained, you can teach him by education how to manufacture this microphone. So intelligence is there, every living entity. Now, to train them how to utilize his intelligence... So one who is fortunate, he becomes trained up in intelligence how to go home, back to home, back to Godhead. And one who is not fortunate, his intelligence is used how to go to hell. That's all. That is duṣkṛtina. To become a member of the hellish condition of life, that also requires intelligence. How to become first-class thief, how to become first-class cheater, first-class drunkard, first-class smuggler—does it not require intelligence? It requires intelligence. But their intelligence is being used for going to hell. Another intelligence is being used to going back to home, back to Godhead. Intelligence is there in both the cases. Now, it is the technique, how to use it. That's all. That requires.
So duṣkṛtina: "Those who are simply engaged in sinful activities and utilizing intelligence in that way," na māṁ prapadyante, "they cannot surrender to Me." So the intelligence is there. Everything is there. Senses are there. They have to be purified. Tat-paratvena nirmalam [Cc. Madhya 19.170]. The Kṛṣṇa consciousness movement is to purify intelligence, not that intelligence is external, pushed in, within him, no, intelligence there, but at the present moment he is polluted. His intelligence is covered with so many dirty things. That has to be cleansed. Ceto-darpaṇa-mārjanam [Cc. Antya 20.12]. That is Kṛṣṇa consciousness movement. His intelligence has to be cleansed. Other... Intelligence is there. Without intelligence, how one can be living being? Then he is stone. The Buddha philosophy, they mean to say that "Kill your intelligence. Then no more suffering from pain or pleasure. Just like stone. It has no feeling or suffering or pleasure." So that is not possible for the living entity to become as dull as the stone. That is not possible.
