According to Tracey Parece, the Boston Top News Examiner, self-help author and motivational speaker Tony Robbins led thousands of people during a motivational event on Thursday, July 19, 2012. This event took place in a park near the San Jose Convention Center in San Jose, California.
The event included multiple firewalks, and 21 people were injured during their walks. Most were treated on the scene, but three were taken to a hospital.
This motivational event was called "Unleash the Power Within." Apparently this is not the first time hot coals were used (view video).
