Puṣṭa Kṛṣṇa: Actually, their philosophy came from rats.
Prabhupāda: Hmm? What is that philosophy? Rat philosophy? This is called vṛścika-taṇḍula-nyāya in Sanskrit. The scorpion is coming from the stock of rice. Actually, the scorpions they lay egg within the stock of rice, and by fermentation the eggs become scorpion and come out. Not that the rice is producing scorpion.
Rādhāvallabha: The scientists know about that, and they say yes, that is very laughable, primitive. But their new theory is simply that life comes from chemicals. So it is actually the same thing.
Hṛdayānanda: Yes, because life is also chemicals.
Puṣṭa Kṛṣṇa: But the fact is that they cannot even manufacture a tiny seed which will fructify.
Prabhupāda: Yes, let them manufacture a seed. From that seed a big tree will come.
Rāmeśvara: They cannot do that.
Candanācārya: Some devotees are saying that cockroaches are coming from the vapors of impure things.
Prabhupāda: Yes, they come. That is called sveda-ja. Just like from perspiration, bugs are coming out. Sveda-ja.
Rādhāvallabha: So isn't that life coming from matter?
Prabhupāda: Not matter. From matter is not coming, but they are taking birth.
Hari-śauri: That's the atmosphere that they get born into.
Rādhāvallabha: So are they coming from eggs, or how are they coming? Just the soul enters the dirt?
Prabhupāda: No. Just like it is a suitable circumstance from which the living entity makes his body.
Rādhāvallabha: But how has the cockroach been formed?
Prabhupāda: Just like embryo. The living entity comes of the two secretions of father and mother emulsified. It creates a situation so that he can stay there and develop a body.
Rādhāvallabha: But it requires some emanation from a cockroach body in order to create another cockroach body. So how can a cockroach body be created from vapors without contact of another cockroach?
Prabhupāda: No, no. Vapor does not create. The individual soul comes there according to his karma and, in that condition, he develops his body. Karmaṇā daiva-netreṇa jantur dehopapattaye (SB 3.31.1).
Rāmeśvara: So the seed of.... The soul is within the vapor?
Prabhupāda: The seed, when it is put into the earth, a situation is created so the soul can develop into a tree.
Rādhāvallabha: But how would the soul develop a particular body...?
Prabhupāda: That is Yamarāja is.... We are reading the Yamarāja incident(?). That's all.
Puṣṭa Kṛṣṇa: Just like how can a living entity take birth in the fire?
Puṣṭa Kṛṣṇa: The argument is that how can an entity take birth in perspiration? His question. So how can a living entity take birth in the fire? Mostly our experience is that entities are taking birth from the earth, but according to the understanding...
