Svarūpa Dāmodara: There are sometimes white, they say, suppose when I am injured, my external something hurts. They say the white blood corpuscles are responsible to protect the body. But when the white blood corpuscles is not enough, then infection normally occurs.
Prabhupāda: Anyway there is change of corpuscles. And with the change of corpuscles there is change of body. That is scientific. Therefore body is changing every moment, so why not after death? Tathā dehāntara-prāptiḥ (BG 2.13).
Svarūpa Dāmodara: So consciousness is also subject to body's changes, change of body.
Prabhupāda: Yes. Body's circumstances association. Saṅgāt sañjāyate kāmaḥ. According to association, atmosphere, circumstances, the desires changes. So that is, desire means consciousness. Just like our boys, they had different consciousness before coming to Kṛṣṇa consciousness. Just like you are also scientist, there are other scientists. But your consciousness is different from theirs. Therefore you could challenge him like that. If you can create life by accumulation of these facts. He says that I do not know. He is not confident in his science.
