Eckhart Tolle said this quote

“ A woman in her thirties came to see me. As she greeted me, I could sense the pain behind her polite and superficial smile. She started telling me her story, and within one second her smile changed into a grimace of pain. Then, she began to sob uncontrollably. She said she felt lonely and unfulfilled. There was much anger and sadness. As a child she had been abused by a physically violent father. I saw quickly that her pain was not caused by her present life circumstances but by an extraordinarily heavy pain-body. Her pain-body had become the filter through which she viewed her life situation. She was not yet able to see the link between the emotional pain and her thoughts, being completely identified with both. She could not yet see that she was feeding the pain-body with her thoughts. In other words, she lived with the burden of a deeply unhappy self. At some level, however, she must have realized that her pain originated within herself, that she was a burden to herself. She was ready to awaken, and this is why she had come. I directed the focus of her attention to what she was feeling inside her body and asked her to sense the emotion directly, instead of through the filter of her unhappy thoughts, her unhappy story. She said she had come expecting me to show her the way out of her unhappiness, not into it. Reluctantly, however, she did what I asked her to do. Tears were rolling down her face, her whole body was shaking. “At this moment, this is what you feel.” I said. “There is nothing you can do about the fact that at this moment this is what you feel. Now, instead of wanting this moment to be different from the way it is, which adds more pain to the pain that is already there, is it possible for you to completely accept that this is what you feel right now?” She was quiet for a moment. Suddenly she looked impatient, as if she was about to get up, and said angrily, “No, I don't want to accept this.” “Who is speaking?” I asked her. “You or the unhappiness in you? Can you see that your unhappiness about being unhappy is just another layer of unhappiness?” She became quiet again. “I am not asking you to do anything. All I'm asking is that you find out whether it is possible for you to allow those feelings to be there. In other words, and this may sound strange, if you don't mind being unhappy, what happens to the unhappiness? Don't you want to find out?” She looked puzzled briefly, and after a minute or so of sitting silently, I suddenly noticed a significant shift in her energy field. She said, “This is weird. I 'm still unhappy, but now there is space around it. It seems to matter less.”This was the first time I heard somebody put it like that: There is space around my unhappiness. That space, of course, comes when there is inner acceptance of whatever you are experiencing in the present moment.I didn't say much else, allowing her to be with the experience. Later she came to understand that the moment she stopped identifying with the feeling, the old painful emotion that lived in her, the moment she put her attention on it directly without trying to resist it, it could no longer control her thinking and so become mixed up with a mentally constructed story called “The Unhappy Me.” Another dimension had come into her life that transcended her personal past – the dimension of Presence. Since you cannot be unhappy without an unhappy story, this was the end of her unhappiness. It was also the beginning of the end of her pain-body. Emotion in itself is not unhappiness. Only emotion plus an unhappy story is unhappiness. When our session came to an end, it was fulfilling to know that I had just witnessed the arising of Presence in another human being. The very reason for our existence in human form is to bring that dimension of consciousness into this world. I had also witnessed a diminishment of the pain-body, not through fighting it but through bringing the light of consciousness to it. ”
