Prabhupāda: Something chunk? What is that original cause, chunk? What is?
Śyāmasundara: Something gas.
Prabhupāda: Gas.
Śyāmasundara: Liquid gas.
Prabhupāda: Hmm. So anyway, that is not sentient; that is material. Gas is also material. Gas is another form, vapor. Vapor . . . vapor is made out of water. Water or . . . vapor is air, major portion of air and minor portion of water. In this way, vapor. So that means it is airy. But no. Air has got its cause. They do not know. Air has got its cause: the sky. The sky has its cause. In this way there is creation. In the Śrīmad-Bhāgavatam everything is explained.
So this Brahma-saṁhitā, the point is, in this Brahma-saṁhitā Kṛṣṇa's name is there. In the Atharva Veda there is Kṛṣṇa's name. So our process of knowledge—if there is Vedic evidence, that is perfect. You don't require to experiment. Experimental knowledge is never perfect. The same example as we have given several times: that which is unknowable, inconceivable, that knowledge you cannot get by experiment.
That is not possible. You have to receive the knowledge from authority. Just like you cannot understand who is your father by experiment, laboratory. Bring every man and analyze him whether he is your father. Is it possible? No. How many men you will bring it in the laboratory? That is not possible. But if you approach to the authority, the mother, immediately you get the knowledge. Ask your mother, "Who is my father?" She'll say: "Here is your father."
That means you receive the knowledge from the authority, not by experimental knowledge. Which is inconceivable, beyond your perception, beyond your imagination, that knowledge you cannot get by experiment. They are trying to make experiment . . . (break) . . . soul. The so-called scientists, they say: "We are trying." You can try on, but it is beyond your experience, beyond your knowledge. Your senses are all imperfect. You can . . . you cannot understand soul by experimental knowledge. You have to hear from the authority. Just like Kṛṣṇa says:
- dehino 'smin yathā dehe
- kaumāraṁ yauvanaṁ jarā
- tathā dehāntaraṁ prāptir
- dhīras tatra na muhyati
- (BG 2.13)
This is the process.
But you can think over. Just like Kṛṣṇa says, dehino 'smin yathā dehe. Dehe means "Within this body, there is the proprietor of the body." That is soul. Now, by experimenting, by taking in somebody's body—just like in medical science they dissect the body—you cannot find out. It is so small. Therefore you are saying: "There is no soul." But there is soul. From your experimental knowledge, you cannot understand where is that soul, but there is soul.
