(Krishna's spiritual and material worlds)
"At present we have contacted a material body, material mind and material intelligence, but when we become free from these material conditions, our spiritual body, spiritual mind and spiritual intelligence become manifest."
(Śrīmad-Bhāgavatam 4.23.11, Purport)
Prabhupāda: Originally, you have got everything. You have got mind, ego, and everything. Just like when I think, ahaṁ brahmāsmi, "I am servant of Kṛṣṇa," that is also ego, "I am." But that is pure. But as soon as I think "I am American," "I am Indian," "I am this body," that is impure. This is impure egoism, and that is pure egoism. So ego is there. Similarly, mind is also there, intelligence is also there, but when it is covered by this material contamination it is called māyā, and when it is out of material contamination, ahaṁ brahmāsmi, "I am servant of Kṛṣṇa. I shall act for Kṛṣṇa, I shall live for Kṛṣṇa, I shall eat for Kṛṣṇa, I shall prepare foodstuff for Kṛṣṇa, I shall sing for Kṛṣṇa—everything Kṛṣṇa," that is liberated stage.
Devotee: So that mind is part of the soul. It's just, it's polluted.
Prabhupāda: Yes. That is a symptom of... Mind is the active principle. Without mind, how can you act? The mind is there. But at the present moment, becoming covered by the material energy, everything is contaminated. Mind is contaminated, the intelligence is contaminated, the ego is contaminated, I, or self, I am contaminated. Everything is contaminated. When you have got fever, there is pain all over the body. There is temperature all over the body. And when the fever is off, there is no temperature. Similarly, it is the difference of consciousness only. As soon as we take material consciousness, it is to be understood in feverish condition. And as soon as you take to Kṛṣṇa consciousness, we are out of feverish condition.
Devotee (2): When they go back to Godhead, some people can remember their past lives?
Devotee (2): In the mind.
Devotee (2): I thought the mind was left behind.
Prabhupāda: No. Actually mind carries you to the next body. So mind goes with you. The material mind, material ego, material intelligence become nil when you are completely liberated. But at that time your spiritual mind acts. It is not very difficult to understand. Somebody is acting under the impression... Just like one of our students, he was acting under the impression that he is Frenchman and doing something subversive, and now he is thinking that "I am Kṛṣṇa's." (laughs) He has stopped all those nonsense. When he was thinking that he's a Frenchman, that mind was there. And now he's thinking that "I am Kṛṣṇa's," the mind is there. So where is the chance of losing the mind?
(Srila Prabhupada Lecture, Montreal, August 17, 1968)
John Mize: When the soul was in the spiritual sky, it also had a mind and an intelligence like here?
Prabhupāda: Oh, yes. Yes. Unless he has got mind, how he misuses intelligence?
John Mize: But he misused that intelligence in his freedom, his independence.
Prabhupāda: Yes. Yes. Mind is there also. That is spiritual mind. Everything is spiritual. There is nothing material. Body spiritual, mind spiritual, intelligence spiritual, he is spiritual, the land spiritual, water spiritual—everything is spiritual. That is spiritual world. Here in the material world, except the spirit soul, everything is material. And he is encumbered with this material atmosphere by twenty-seven stratas, layers. The five elements, gross elements, then ten senses, and then three guṇas... In this way there are twenty-seven layers. He is within, and he has to be taken out. That is called liberation. Just like if you are covered with twenty-seven layers of dirty things, so it is very difficult position. But there is process to clear the garbage and take him out. That is Kṛṣṇa conscious movement, to take the soul out of the covering of twenty-seven layers of material atmosphere. That śloka is naṣṭa-prāyeṣu abhadreṣu: "almost cleansed." Abhadra, abhadra means dirty things. So this clearing process going on. When it is almost cleansed the man feels, "Oh..." And that process: nityaṁ bhāgavata-sevayā (SB 1.2.18), constantly being engaged in the service of Bhāgavata, grantha-Bhāgavata and the person Bhāgavata. Then it will be cleansed. And then, when he comes out, that is brahma-bhūtaḥ prasannātmā (Bg. 18.54), "Oh, I am now free." Na śocati na..., no more lamentation, no more greediness. Everything finished. Then he begins his real business as part and parcel of God. That is perfection.
(Srila Prabhupada Conversation with Dr. John Mize, Los Angeles, June 23, 1975)
"Regarding your question about the difference between mind and soul, the mind is one of the senses, and the soul is the owner of the senses, including the mind. The mind is material, just like the material body, but when the material coverings are taken away, as we revive our spiritual body, similarly we revive our spiritual mind also. At the present moment, my material mind, intelligence and ego is carrying me in different types of bodies, because mind has different desires, and it carries the soul just like finer air carries the flavor of the flower or some other smell. So the mind is an instrument, and the soul is the worker of the instrument."
(Srila Prabhupada Letter, May 8, 1969)
