You may remember the story of how the devil and a friend of his were walking down the street, when they saw ahead of them a man stoop down and pick up something from the ground, look at it, and put it away in his pocket. The friend said to the devil, "What did that man pick up?" "He picked up a piece of the truth," said the devil. "That is a very bad business for you, then," said his friend. "Oh, not at all," the devil replied, "I am going to help him organize it."
All authority of any kind, especially in the field of thought and understanding, is the most destructive, evil thing. Leaders destroy the followers and followers destroy the leaders. You have to be your own teacher and your own disciple. You have to question everything that man has accepted as valuable, as necessary.
So when you are listening to somebody, completely, attentively, then you are listening not only to the words, but also to the feeling of what is being conveyed, to the whole of it, not part of it.
