Ouch—mind was overcome by matter at a self-help seminar last night when participants scorched their feet during a motivational walk across hot coals. The San Jose Fire Department swooped in and treated "several" people for burn injuries, reports the Mercury News. The event was hosted by feel-good guru Tony Robbins and held at the San Jose Convention Center. The injuries occurred during a portion called "The Firewalk Experience" which involves strolling over coals heated between 1,200 and 2,000 degrees Fahrenheit. (More Tony Robbins stories.)
