Concentration is not meditation; concentration is the method of science. It is scientific methodology. A man of science needs the deep discipline of concentration, but a man of science is not expected to be compassionate. There is no need. In fact, a man of science becomes more and more violent with nature. All scientific progress is based on violence towards nature. It is destructive because, in the first place, the scientific man is destructive to his own expanding consciousness. Rather than expanding his consciousness he narrows it down, makes it exclusive, one-pointed. It is a coercion, violence.
