At the University of Chicago, beginning in 1953, Eugene Gendlin did 15 years of research analyzing what made psychotherapy either successful or unsuccessful.
Gendlin found that, without exception, the successful patient intuitively focuses inside himself on a very subtle and vague internal bodily awareness-or "felt sense"-which contains information that, if attended to or focused on, holds the key to the resolution of the problems the patient is experiencing [REF].
