Dr. Weir: That's where your line is so very good in saying that the real evolution of man's mind has been his ability to produce more and more the functions of whatever the mind may be. But the mind is just as indivisible as God. We know what the brain is, but we don't know what the mind is. Yet more and more of it under conscious control instead of being irrationally eruptive(?).
Prabhupāda: But there is the summum bonum of that realization. That is explained in Bhagavad-gītā: bahūnāṁ janmanām ante, jñānavān māṁ prapadyate (BG 7.19). After many, many births of this mental evolutionary process, when actually he becomes wise he becomes God conscious and surrenders to God. That is real evolution(?). That evolution will go on. But when it comes to the summit, that is God realization. Vāsudevaḥ sarvam iti (BG 7.19). God is cause of all causes. That is final realization. Unless one comes to that point he has not come to the perfection of evolutionary process of the mind and intelligence.
