Śyāmasundara: When science tries to investigate something, they assume that what they are investigating is static, that it is a constant, that it is not changing, that it's static, mechanical. But the life force, he says, is dynamic; it's always changing, unpredictable.
Prabhupāda: Yes. Because it is living force, it must be dynamic. It is not a dead stone. Because it is living force, it must be dynamic. We are all living force, sitting here, we may sit down or we may go away. That nobody can check. Similarly, we are dynamic forces, and God does not interfere with our dynamic force. He allows us, "Do whatever you like." Because if He interferes with our independence, then we are no longer living entities; we become dead stones. So God does not interfere. He gives us full freedom. But at the same time He comes down and instructs us, "But why you are engaged in this foolish activity? Please come to Me, back to home, back to Godhead, (indistinct)."
Śyāmasundara: So if he says that the physical world...
Līlāvatī: Does that mean that the spiritual body changes, Prabhupāda?
Prabhupāda: Not spiritual body, material body. Spiritual body cannot be changed.
Śyāmasundara: No. We're not talking about bodies, we're talking about the life force.
Prabhupāda: Life force means that the spirit soul has got spiritual body. That I have explained several times. Just like you have got this body. When you cut your coat, it is according to the body. Because we have hands, legs, therefore it is to be understood that this dress is made according to that real body. So originally the spirit soul has got body, so these physical elements are just like a covering, exactly to the size of the hands, legs, everything.
Śyāmasundara: He says that this life form is unpredictable, that it's always creating new things, new manifestations.
Prabhupāda: Yes. It is creating new things in the material phenomena. Otherwise how he is spiritually situated, there is no such changes. The only one business is to serve Kṛṣṇa, although when we satisfy Kṛṣṇa there are many varieties. That is spiritual varieties. At the present moment, because He is lover of varieties, we are creating this material (indistinct), varieties of body, and this is subjected to threefold miseries and difficulties—birth, death, old age, disease. So, so long we are materially entrapped, our so-called (indistinct) force is creating troubles. We are becoming more and more entangled.
