I guess non-mainstream methodologies/frameworks like NLP, chakras and yoga were on to something when they said that emotions have locations in the body.
By the way, emotions having a bodily basis and function is absolutely mainstream psychology, I think Darwin wrote about it, William James, Paul Ekman of course... Mindfullness is included in some therapies. Even new agey ideas by likes of Lowen and Reich are often mentioned in academic textbooks.
