Thoughts are forms of energy. If thoughts are forms of energy, then emotions are probably forms of energy also. I suppose there are biochemical elements to thoughts and emotions. I really don't know but I do believe there is at least an energetic effect of thoughts and emotions. Feel free to debate me. This is a debate forum and I won't mind.
Where do you feel emotions especially strong emotions when you feel them? You feel them in your body. You don't feel the feeling of rage or attraction only inside of your mind.
The energy of the body is partly why I believe EFT works. Tapping codes are used on parts of the body. According to people like Gary Craig (the founder of EFT), they believe psychologists have been looking in the wrong place. They only look in the mind. This is why people who have been traumatized by war get over their worst experiences within hours or even a few minutes with EFT.
