While at the Berkeley TM center, I worked with a world class physiology professor there to do an EEG study of yogic flying, got permission for her to watch a flying session and begin designing the study. She was a meditator with a positive view of TM, was excited about the project. After seeing a flying session, she said it was impossible to get anything close to an accurate reading of yogic flying using an EEG and the coherence studies "during liftoff" were nonsense. ------------------------ Yahoo!
