Thanks for the topic Cristy.
This committee in the head business, is to me one of the hardest things to overcome, but I have made progress with it, and found it's great when I can live without constant thinking. I don't usually like quoting sections from his books, but like avaneesh said Tolle has some of the best answers I have found on this subject, I read this part just yesterday, so it's easy to find and quote -
FALLING BELOW AND RISING ABOVE THOUGHT
When you are very tired, you may become more peaceful, more relaxed than in your usual state. this is because thinking is subsiding, and so you can't remember your mindmade problematic self anymore. You are moving toward sleep. When you drink alcohol or take certain drugs (provided they don't trigger your painbody), you may also feel more relaxed, more carefree, and perhaps more alive a for a while. You may start singing and dancing, which since ancient times are expressions of the joy of life. Because you are less burdened by your mind, you can glimpse the joy of Being. Perhaps this is the reason alcohol is also called “spirit.” But there is a high price to pay: unconsciousness. Instead of rising above thought, you have fallen below it. A few more drinks, and you will have regressed to the vegetable realm. Space consciousness has little to do with being “spaced out.” Both states are beyond thought. This they have in common. The fundamental difference, however, is that in the former, you rise above thought; in the latter, you fall below it. One is the next step in the evolution of human consciousness, the other a regression to a stage we left behind eons ago.
Why I don't like quoting parts, is that without reading the whole book, (this is from 'A New Earth'), I believe it may look to some people like a lot of mumbo jumbo space age nonsense, and it took me a couple of reads and pondering on the words to start grasping it. All the spiritual books which speak about contemplative prayer and so on, are I think leading us in the same direction, trying to get us out of over thinking everything. I believe it's the answer to a really happy stress free life, (a road the 12 steps started us nicely on), maybe not easy to do at first, but then good things are seldom easy.
