Who stated this quote? What is the meaning behind the words? What is your opinion on the text?  “When we come together to talk, or otherwise to act in common, can each one of us be aware of the subtle fear and pleasure sensations that “block” his ability to listen freely? Without this awareness, the injunction to listen to the whole of what is said will have little meaning. But if each one of us can give full attention to what is actually “blocking” communication while he is also attending properly to the content of what is communicated, then we may be able to create something new between us, something of very special significance for bringing to an end the at present insoluble problems of the individual and society.”
