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?
Prabhupāda: Hmm?
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...
Prabhupāda: So how the fishes are born in the water? How the other living entities, they remain in the air? Or without air? There are five elements: earth, water, fire, air.... Anywhere, the living entities can take birth. Sarva-ga. Sthāṇur sarva-gataḥ acalo 'yam. You read all these words of Bhagavad-gītā. Sarva-ga. From anywhere, he can take birth.
Devotee: Do the living entities who are born from perspiration require a mother and father?
Prabhupāda: No. No. There is mother. That perspiration is mother.
Rādhāvallabha: So the reason why they get a particular body...
Prabhupāda: And the father is God.
Rādhāvallabha: So they are just getting a particular body just due to Yamarāja.
Prabhupāda: Yes, according to the decision of the Yamarāja, he has to get a particular type of body.
Rādhāvallabha: The scientists don't know this.
Hari-śauri: It's very confusing, Prabhupāda.
