The brain is not forcing itself to be quiet. If it is forcing itself to be quiet then it is still the operation of the past. In that there is division, there is conflict, there is discipline and all the rest of it. But if the old brain understands, or sees the truth—that as long as it is in constant response to any stimulus, it must operate along the old lines—if the old brain sees the truth of that, then it becomes quiet. It is the truth that brings about quietness—not the intention to be quiet.
