I'm continuing to read Tolle's A NEW EARTH. And it continues to hit me right where I'm at. It reminds me a good deal of what Friedmann said in A FAILURE OF NERVE and what DeMello is talking about in AWARENESS.
I just began the chapter that deals with emotions and the mind, and I thought I'd share a bit from the book...
Although the body is very intelligent, it cannot tell the difference between an actual situation and a thought. It reacts to every thought as if it were a reality. It doesn't know it is just a thought. To the body, a worrisome, fearful thought means "I am in danger," and it responds accordingly, even though you might be lying in a warm and comfortable bed at night. The heart beats faster, muscles contract, breathing becomes rapid. There is a buildup of energy, but since the danger is only a mental fiction, the energy has no outlet. Part of it is fed back to the mind and generates even more anxious thought. The rest of the energy turns toxic and interferes with the harmonious functioning of the body.
[We] are beginning to recognize the connection between negative emotional states and physical disease. An emotion that does harm to the body also infects the people you come into contact with and indirectly, through a process of chain reaction, countless others you never meet.
