Prabhupāda: So the modern theory that life is made possible by chemical evolution is not correct. Or the Darwin's Theory, evolution of matter. No. The... They are missing the soul. That is their mistake. They are simply observing the material cover. That is the basic mistake of modern civilization. They have no information that within the body there is the spirit soul. That is the basic principle of material development. Matter is coming out of spirit, not that spirit is coming out of matter. They think by combination of matter there is a stage when living symptoms are visible. That is not the fact. The fact is that spirit soul is there, and therefore matter is developing.
Matter is external, and spirit soul is internal. So this internal spirit soul is coming from the Supreme Soul. Therefore it is said, daivāt kṣubhita-dharmiṇyāṁ svasyāṁ yonau paraḥ pumān (SB 3.26.19). Paraḥ pumān, the Supreme Person, the supreme living entity... Nityo nityānāṁ cetanaś cetanānām (Kaṭha Upaniṣad 2.2.13). The supreme living entity is Kṛṣṇa, and Kṛṣṇa says in the Bhagavad-gītā, ahaṁ bīja-pradaḥ pitā (BG 14.4). He is the origin of living entities. Ahaṁ sarvasya prabhavaḥ (BG 10.8). The supreme living entity is the source of both matter and spirit, not that spirit has come out of matter at a certain condition. That is not the fact. So this material nature is impregnated just like a female is impregnated by the male. Otherwise the female cannot give birth to any child. Similarly, this material nature cannot produce anything without being agitated and impregnated by the Supreme Soul. This is the fact. So you can read the purport.
Nitāi: "This impregnation of material nature is described in the Bhagavad-gītā, Fourteenth Chapter, third verse. Material nature's primal factor is the mahat-tattva, or breeding source of all varieties. This part of material nature, which is called pradhāna as well as Brahman, is impregnated by the Supreme Personality of Godhead and delivers varieties of living entities. Material nature in this connection is called Brahman because it is a perverted reflection of the spiritual nature."
Prabhupāda: These varieties... According to the Western Darwin's theory, they do not give any nice description of the varieties. But the varieties of living entities are there before creation. They become manifest in next creation. Just like in this creation one is dying as demigod, I mean to say, at the last dissolution, and one is dying as dog, or one is dying as a fish. So when the next creation will come out, they also will come out in that way, again as fish, because his activities in the form of fish was not completed. So one has to complete the term of one particular type of body. That is the law of nature. So they remain in dormant stage in the body of Mahā-Viṣṇu at the time of dissolution. Prakṛtiṁ yānti māmikām, in the Bhagavad-gītā it is said. Prakṛtiṁ yānti māmi... Then, at the time of creation, they come out again in the same body as it was in the last creation. Therefore Bhaktivinoda Ṭhākura says, anādi karama-phale, paḍi' bhavārṇava-jale. Of course, the evolution takes place, but at the time of creation the particular type of body which I inherited in my last birth or millennium I get again, and again begin evolution. This is the process, going on. Bhūtvā bhūtvā pralīyate (BG 8.19). The dissolution takes place.
So varieties are already there, not that in this creation it begins. Otherwise how Brahmā is created first? Brahmā is the most intelligent creature, so intelligent that he is given the power of creating this universe. So not that in the beginning there was no intelligence. The first-class intelligence is there in the beginning of the creation. Read.
