In the Bhagavad-gītā it is said,
- bhūmir āpo 'nalo vāyuḥ
- khaṁ mano buddhir eva ca
- bhinnā me prakṛtir aṣṭadhā
- (BG 7.4)
These materialistic persons—scientists, physists and other speculators—they're dealing with these elements, material—earth, water, fire, air, ether, up to mind, psychology, or, little advanced, intelligence, but no more. They are dealing in their university, colleges, educational institution. They are concerned with these elements, material. They have no spiritual knowledge. Kṛṣṇa said... We get information from the Bhagavad-gītā, apareyam: "These eight elements, they are inferior." Therefore, because they are dealing with this inferior nature only, their knowledge is inferior. This is a fact. It is not that I am accusing. No. This is the... They have no information. Big, big professor, they say that this body finished... "Body finished" means pañcatva-prāpta. They do not know that there is another body, subtle body—mind, intelligence, ego. They do not know. They are thinking this earth, water, air, fire, ether, that much..., "This is finished. I see, either you burn the body or bury the body, finished, everything finished. And where is other thing?" So they have no knowledge. So they have no knowledge even of the subtle body, earth, water, which carries the soul, and what they'll know about the soul?
So Kṛṣṇa gives information in the Bhagavad-gītā, apareyam: "These elements, even up to mind, intelligence, ego," bhinnā, "they are My separated energy, separated energy. And," apareyam, "this is inferior. And there is another, superior nature." Apareyam itas tv viddhi me prakṛtiṁ parā (BG 7.5). Parā means "superior." Now, they may be asking, "What is that? We know these elements only. What is that another, superior energy?" Jīva bhūtaḥ mahā-bāho (BG 7.5), clearly said: "That is living..." And they are thinking that there is no other superior energy except these eight material elements or five elements. Therefore they are in ignorance. It is for the first time they are getting some knowledge, Bhagavad-gītā As It Is, and from that they can know that there is another, superior energy, who is jīva-bhūtaḥ. The living entity which is moving the body, that is superior energy. So they have no information, neither there is an attempt to understand that superior energy in their universities or institution. Therefore they are mūḍha, mūḍhas. They may be very much puffed up of their so-called knowledge, but according to Vedic knowledge they are mūḍhas. And if one cannot understand the superior energy, prakṛti, nature, then how one can understand God? That is not possible. Then again, dealings between God and the superior energy, that is bhakti. It is very difficult. Manuṣyāṇāṁ sahasreṣu kaścid yatati siddhaye (BG 7.3). That siddhaye means to understand that superior energy. That is siddhi. And after that, one can understand Kṛṣṇa.
So it is very difficult, especially in this age. Mandāḥ sumanda-matayo (SB 1.1.10). They are... Mandāḥ means they are not interested, or even they are little interested, they are very slow. They do not understand this is the prime knowledge. And first of all you must know it, athāto brahma jijñāsā, that superior knowledge. That is required. But everyone is neglecting. There is no inquisitiveness even what is that thing which is moving this body. There is no inquiry. They think automatically, by combination of this matter... They are still persisting on this point, and when you challenge, "You take this chemical and prepare the living force," they'll say, "That I cannot do." And what is this? If you cannot do, then why you are speaking like nonsense, that "The combination of matter or chemicals gives the life"? You take the chemicals. Our Dr. Svarūpa Dāmodara in the California University... One big professor came to lecture on chemical evolution, and he challenged immediately, that "If I give you the chemicals, can you produce life?" He said, "That I cannot say." (chuckles) So this is their position. They cannot prove it. They cannot do it.
