I often find that people confuse inner peace with some sense of insensibility whenever something goes wrong. In such cases inner peace is a permit for destruction: The unyielding optimist will pretend that the forest is not burning either because he is too lazy or too afraid to go and put the fire out.
Just as one spoils the stomach by overfeeding and thereby impairs the whole body, so can one overload and choke the mind by giving it too much nourishment. For the more one reads the fewer are the traces left of what one has read; the mind is like a tablet that has been written over and over. Hence it is impossible to reflect; and it is only by reflection that one can assimilate what one has read. If one reads straight ahead without pondering over it later, what has been read does not take root, but is for the most part lost.
