Prabhupāda: Therefore I say, imperfect science.
Bob: Science may, though, say something. It is said in science that energy is never destroyed. It is just changed.
Prabhupāda: That's all right, but how the energy is working in future, that science does not know.
Bob: Yeah.
Prabhupāda: How the energy is diverted, how by different manipulation the energy is working differently. Just like electric energy, by different handling it is creating heater and it is creating cooler. Just opposite. But the same electric energy. So similarly, these energies, living energy, how it is being directed, which way it is going, how it is fructifying in the next life, so they do not know. They do not know. And in the Bhagavad-gītā it is very simplified. Vāsāṁsi jīrṇāni yathā vihāya (BG 2.22). You are covered by this dress, by this shirt. When this shirt is not workable you change it. Similarly, this body is just like shirt and coat, when it is no longer workable, we have to change.
