Bob: But when you have some knowledge of God, then life is not so miserable.
Prabhupāda: No, some knowledge will not do. You must have perfect knowledge. Janma karma me divyaṁ yo jānāti tattvataḥ (BG 4.9). Tattvataḥ means perfect. That perfect knowledge is being taught in the Bhagavad-gītā. So, we are giving chance to the human society to learn Bhagavad-gītā as it is and make his life perfect. That is Kṛṣṇa consciousness movement. What your science says about the transmigration of the soul?
Bob: I think that science cannot deny it, by scientific methods cannot deny it, or does scientific method show it. Science does not know of it.
Prabhupāda: Therefore I say, imperfect science.
