Devotee (1): What if one keeps falling down from following the regulative principles?

Prabhupāda: He's falling down? If he's falling down from regulative principles, that means he's falling down to the material world. Falling down means falling down.

Devotee (2): (break) ...from the regulative principles and feels anxiety, then that anxiety is material anxiety.

Prabhupāda: Yes.

(Morning walk--------Melbourne).

Devotee (1): What if we're going on saṅkīrtana or something like that, how can we be sure that we won't fall down, we won't overendeavor? How can we be sure that we're not pushing ourselves too much?

Prabhupāda: You will feel sure as you make progress. Just like when you are eating, hungry, as you feel satisfaction and hunger satisfied, you can know yourself. (break)

Guest (3) (man): What if you hear in your heart but don't act in your life.

Prabhupāda: Hm?

Puṣṭa Kṛṣṇa: What if you hear but don't act accordingly in your practical life?

Guest (3): You feel it in your heart...

Prabhupāda: No, hear means you do it in practical life. Otherwise what is the hearing? Then just like one stone, he has got ear. That is not atten... Hearing means it will react. That is hearing. The more you hear, it will react. Then you practically do it. But everything comes by hearing. So hearing is so important. Just like even in your ordinary education you go to the school, college, and hear from your professor. Hearing is so important. Then you become perfect. You take your degrees. Similarly, the science of God, you simply hear about it. Śravaṇaṁ kīrtanam. Then, gradually, it will purify. Hearing means purifying the dirty things within the heart. That is hearing. Ceto-darpaṇa-mārjanam (CC.2:20:12). Śṛṇvatāṁ sva-kathāḥ kṛṣṇaḥ puṇya-śravaṇa-kīrtanaḥ (S.B.1:2:17). Because it is spiritual, hearing has got a potency to purify you. This is not ordinary hearing. This is spiritual hearing, so it has got a potency. Śṛṇvatāṁ sva-kathāḥ kṛṣṇaḥ puṇya-śravaṇa-kīrtanaḥ. Anyone who takes part in this process of hearing and chanting, he becomes pious, purified. Just like if you touch some way or other the fire, it will act, similarly, Kṛṣṇa is spiritual. You hear about Kṛṣṇa; then it will act. Then you'll be purified.

(Lecture on Bhagavad-Gita--------Melbourne).

Hayagrīva: ...degenerating. What is the cause of man's physical, mental and spiritual deterioration in the succeeding yugas?

Prabhupāda: That is education. Every individual person, he is a soul, and he has got a particular type of body. Especially in the human body he requires education. What is this animal and what is higher than human race, these are Vedic description. So there are 8,400,000 different forms of life, and the body is being evolved. The body is machine, and the individual soul desires and he gets a suitable body made by material nature under the order of God. This is Vedic idea, as it is said in the Bhagavad-gītā, īśvaraḥ sarva-bhūtānāṁ hṛd-deśe arjuna tiṣṭhati (B.G.18:61). God is existing within the core of everyone's heart, and the individual soul is desiring something, and upon the order God he is given a machine made by material nature. So this is evolution, and even a man, although he is human form of body, he can again degenerate to animal form of body according to his desire. Tathā dehāntara-prāptiḥ (B.G.2:13). He has to change the body, and the body is changed according to his work and desire. In the animal kingdom they have also desires, but they are under the laws of nature changing body, and one is given the chance to become a human being, and then he may desire, and according to his desires he gets the next body. If he likes, he can go higher forms of life, and if he degenerates he goes lower form of life.
