"Fire officials said 21 people at an event hosted by motivational speaker Tony Robbins suffered burns while walking across hot coals, and three of the injured were treated at hospitals.

The injuries took place during the first day Thursday of a four-day event at the San Jose Convention Center hosted by Robbins called "Unleash the Power Within." Most of those hurt had second and third degree burns, said San Jose Fire Department Capt. Reggie Williams.

Walking across hot coals heated to between 1,200 to 2,000 degrees provides attendees an opportunity to "understand that there is absolutely nothing you can overcome," according to the motivational speaker's website."

I suspect that the phrase "there is absolutely nothing you can overcome" is a typo and that there's a missing apostrophe and "t".

That's interesting. I went through an EST training seminar awhile back and at the end of the training, which lasted about 2 months, we walked on coals.

I found it to be an interesting, positive, and exhilarating experience. I don't claim to understand it, but I know that of the 30-odd people who did it that night, none complained of being burned.

I did a little research and the physics of it are such that it's understandable to science for the most part, except in cases where one remains stationary on the coals for any length of time, or does a very long walk.
