A Few Things to Remember When Worry Takes Over

1. You are not your worry, thoughts, emotions or even your mind.
- "The beginning of freedom is the realization that you are not the possessing entity - the thinker. The moment you start watching the thinker, a higher level of consciousness becomes activated."

-"Learn to disidentify from your mind. Every time you create a gap in the stream of mind, the light of your consciousness grows stronger." -Eckhart Tolle, The Power of Now

2. Worry cannot exist in the present.
Worry is fueled by the ego which thrives in the past or future only.

3. Worry can be confined.
Here is an awesome technique to stop or control your worry:

"Want to confine your worry? Try scheduling ten to thirty minutes a day for worry. Use this time to visualize your anxious feelings, write them down, and come up with an action plan for dealing with the root causes of your worry. If the worry reappears outside this scheduled time, postpone it until the next worry period."  - 5 Things to Remember When Worry Takes Over (So You Can Let It Go)

How to manage the emotional Pain-body:
Pain-body = Accumulated pain acting as a negative energy field that occupies your body and mind. It is the dark shadow cast by the ego. The pain-body, like the ego, is afraid of being found out. 
 "It's survival depends on your unconscious fear of facing the pain that lives in you. But if you don't face it, if you don't bring the light of your consciousness into the pain, you will be forced to relive it again and again." - Eckhart Tolle, The Power of Now

Here is Tolle's formula for dealing with the Pain-body:
1- Focus attention on the feeling inside you.
2- Know that it is the Pain-body.
3- Accept that it is there.
4- Don't think about it - don't let the feeling turn into thinking.
5- Don't judge or analyze.
6- Don't make an identity for yourself oout of it.
7- Stay present, and continue to be the observer of what is happening inside you.
8- Become aware not only of the emotional pain but also of "the one who observes," the silent watcher. This is the Power of Now, the power of your own conscious presence. Then see what happens.
