Śyāmasundara: How does our philosophy define mind and intelligence?
Prabhupāda: Mind is instrument. The mind's position is accepting and rejecting. Intellect helps the mind what to reject and what to accept. And that intelligence is of the soul. That ground of intelligence is the soul. First of all bodily concept is gross life, ordinary, like animals, they do not know except the body. Higher than bodily concept of life, the exercise of the mind, mental speculation. That mental speculation is adjusted by intelligence and that intelligence belongs to the soul. Therefore soul is the ultimate and soul is the part and parcel of God. Therefore God is the supreme. So the mental speculation or the evolution of mental exercise when it comes to the summit, that is God realization. Vāsudevaḥ sarvam iti, sa mahātmā sudurlabhaḥ (BG 7.19). When one realizes "God is everything," that mahātmā, that great soul is very rare. That is the statement in Bhagavad-gītā. Mahātmā means whose mind is great. The mind is great. He's not thinking ordinary things. He's thinking of greater subject matter. They are called mahātmā, broader minded, broad-minded.
Dr. Weir: Do you differentiate, as you would do, it's only a matter of attempting to comprehend the differences (indistinct) of things, the difference between thinking and feeling as rational functions?
Prabhupāda: That is the function of the mind, thinking, feeling and willing. Psychological activity.
Dr. Weir: Do you differentiate them separately?
Prabhupāda: Oh, yes.
Dr. Weir: And intuition as well?
Prabhupāda: Saṅkalpa, vikalpa. This is, in Sanskrit it is called saṅkalpa, vikalpa or accepting and rejecting. That is mind's function. I think something and again I reject it.
Dr. Weir: Well, you also react too.
Prabhupāda: You can say what you like but the function of the mind is flickering. Just like when Arjuna was advised by Kṛṣṇa to train the mind by meditation, by yoga system. He said that "Kṛṣṇa, it is very difficult for me." Cañcalaṁ hi manaḥ kṛṣṇa pramāthi balavad dṛḍham (BG 6.34). My mind is very, I mean to say, agitated. I think to control the mind is as impossible as controlling the wind. Cañcalaṁ hi manaḥ kṛṣṇa pramāthi ba..., vāyor iva suduṣkaram. And it is very difficult to (indistinct) high wind and if you want to control it, as it is impossible. Similarly I think the activities of the mind, thinking, feeling and willing, to control them is very difficult for me. So actually that is the position. So long we shall be on the mental platform there will be no fixity of conclusion. That is not possible. We have to accept something for the time being, then again reject it. Therefore all mental speculators differ. Nāsau munir yasya mataṁ na... A philosopher is not philosopher until he differs from other philosophers. Nāsau munir yasya mataṁ na... Unless you place a different thesis he will not be accepted as a good philosopher.
Dr. Weir: There it differs from science. Because if science is actually correct it can only be one.
Prabhupāda: But philosophy is taken as the science of sciences.
Dr. Weir: Theology used to be that. Yes.
Prabhupāda: Yes.
Dr. Weir: It shows a misconception of the word science.
