Walking across hot coals is a well-known ritual for the thousands of followers of famed motivational guru Tony Robbins, but the empowering method resulted in anguish for several guests.
During the fire walk in Dallas Thursday night, a total of 30 people were treated for burns, with five of them having to be hospitalized.
Inside Edition spoke to Melissa Seureau, who posted a photo of her burned and blistered foot on Twitter.
"My feet were on fire. They took a water hose and cooled them off like they did for everyone. Then, the blisters and the burns were overwhelming," she said.
Melissa also took a photo of the makeshift emergency room set up to treat the fire walk victims.
"Why did I do this? Why did I drink the Kool-Aid with all of these other people? This was an idiot decision to make. I felt like I was smarter than that," she said.
Cell phone video from the event shows thousands of guests at the motivational conference working up the courage to do the walk. It's supposed to help them overcome fear.
Thousands of people made it through safely but others were not as lucky.
Narcissism may have contributed to the blame, as witnesses said some people doing the fire walk were distracted by taking selfies while walking across the hot coals.
"The first step I took I was burning. The second step I took my other foot burned. So, I don’t see how anyone could possibly take a selfie while walking on coals," Seureau said.
A spokesperson for Tony Robbins is defending the fire walk, saying in a statement: "At an Unleash the Power Within seminar in Dallas, seven thousand attendees successfully participated in a fire walk which has been a celebrated part of this event for 35 years.
"It is always the goal to have no guests with any discomfort afterwards but it’s not uncommon to have fewer than 1 percent of participants experience 'hot spots' which is similar to a sunburn which can be treated with aloe. As always there were trained medical and event staff at the fire walk specifically to offer quick and easy remedies for any soreness.
"Someone unfamiliar with the process of the fire walk called 911 reporting the need for emergency services vehicles to be dispatched. While there was no need for emergency personnel we are grateful to the quick and robust response from Dallas emergency services, only 5 of 7,000 participants requested any examination beyond what was readily available on site.
"We are pleased to have completed another successful fire walk for 7,000 guests and look forward to the remainder of an outstanding weekend with them."
