A religious mind is concerned with the totality - not with a particular function, but with the total functioning of human existence. The brain is concerned with a particular function; it specializes. It functions in specialization as a scientist, a doctor, an engineer, a musician, an artist, a writer. It is these specialized, narrowed-down techniques that create division, not only inwardly but outwardly. The scientist is probably regarded as the most important man required by society just now, as is the doctor. So function becomes all-important; and with it goes status, status being prestige. So where there is specialization there must be contradiction and a narrowing-down, and that is the function of the brain .
