I asked many months ago (I think)and now several weeks ago because my topic wasnt named right (check this out being the topic name) how to lower effectly, your brain waves. I've found the answer and proven it worked.
Heres the method:
Place your palm of your hand on your forehead. There is a section of the brain called the "corrector" which is 3-5 cm beneth your palm.
then rub your forehead several times and now imagine this small section of your brain (guessing the size of your forehead) turning to a block of ice.
Through that method you will consciously lower the temporature of your brain, hence lowering the brain waves. (HEHEHE)
Also you can do the exact reverse, make your brain warm thereby increasing traffic thought.
Also, hidden positive effects may and will occur. Enjoy it, its fun. Some side effects will include your hands becoming cold(for some reason or another). I can now use CHI energy to lower or raise the temperature of my hands. Also I will later disclose the answer to the question I have been seeking to for years, How do we increase our IQ?
