Prabhupāda: I have no difficulty to become the greatest scientist. Because I take the knowledge from the greatest scientist. (pause) (break) "This earth, water, fire, air, ether, mind, intelligence and ego—they are My eight separated energies."
Bob: They're separate energies?
Prabhupāda: Yes.
Brahmānanda: Separated.
Prabhupāda: Separated. Separate, no? Just like this milk. What is this milk? The separated energy of the cow. Is it not? It is the manifestation of the separated energy of cow.
Śyāmasundara: Is it like a by-product?
Prabhupāda: Yes.
Bob: So what is the significance of this energy being separated from Kṛṣṇa?
Prabhupāda: Separated means this is made out of the body of the cow, but is is not cow. That is separation.
