Śyāmasundara: He says that behavior is classified under different functions, for example there is sensory behavior, thinking behavior, fear and emotional behavior...
Prabhupāda: That is (indistinct), because the animals, the consciousness is not developed, and the animals' behavior is different. Similarly, if a man is not in this Kṛṣṇa consciousness, (indistinct) any difference? Kṛṣṇa conscious person, he'll not act anything like killing one animal, but another who is not Kṛṣṇa conscious, he will kill animals: "I must kill. I must kill." But the same man, when he is brought into Kṛṣṇa consciousness, he'll refuse. Just like the shikari, (indistinct), he was killing animal, half dead, he would enjoy. The same man, by grace of Nārada, when he became Vaiṣṇava, he was not prepared to kill even one ant. So the man is the same, the consciousness is different. So our program is like that. To bring man into Kṛṣṇa consciousness, he will become perfect.
Śyāmasundara: He says that these different functions, people can be typified or classified as being more or less in one of these types of functions. We describe a man as a thinking man or a feeling man, a sensory man...
Prabhupāda: That we also say, that just like brāhmaṇa, kṣatriya, vaiśya, śūdra—in terms of different stages of consciousness. So the highest stage is the Vaiṣṇava.
Śyāmasundara: How is..., how does Vaiṣṇava act? What are his...?
Prabhupāda: Vaiṣṇava acts in terms of his relationship with Kṛṣṇa, God.
Śyāmasundara: So he is both. He is all these things. He is thinking, he is feeling...
Prabhupāda: Yes. Vaiṣṇava means fully Kṛṣṇa conscious. That's all.
Śyāmasundara: So his idea is that everyone adapts to their environment, either as, according to one of these three things: extroversion, introversion, or a dominant function. So...
Prabhupāda: That we also say. According to material condition of life, they differ, they are classified. The highest stage is Vaiṣṇava. He is completely transcendental (to) material condition. Next the brāhmaṇa, then next the kṣatriya, then next the vaiśya, then next the śūdra, and next means less than śūdra, all caṇḍālas. But Kṛṣṇa consciousness, because that is natural, even from the caṇḍāla stage one can be brought to the highest transcendental stage of Vaiṣṇava.
Śyāmasundara: So would you say that the lower stages of life are, could be termed irrational, and the higher stages of life termed rational?
Prabhupāda: Yes. Righteous.
Śyāmasundara: So the consciousness becomes more and more developed...
Prabhupāda: Yes.
Śyāmasundara: ...as we proceed higher.
Prabhupāda: Not developed. Uncovered. There are different layers of material contamination. So that has to be cleansed. (aside:) You can come this side. (indistinct). The more the layers are cleansed, his original consciousness come out. That is Caitanya Mahāprabhu says, ceto-darpaṇa-mārjanam (CC Antya 20.12), cleaning the dirty things accumulated on the heart.
Śyāmasundara: So consciousness is not the (indistinct)...
Prabhupāda: Consciousness, as soon as they (indistinct), then consciousness is there. That is the symptom of living condition.
