It's actually a pretty cool experience. Also learned how to spit fire during one of those events.
Now, I UNDERSTAND that this is all science and you shouldn't get hurt etc. etc. etc..
However, even understanding the SCIENCE behind it and all of it being 100% logical, all of that goes out of the window once YOU stand in front of one of those beds of coals. To me it was serious gut check time.
Once you do it - it is really NO big deal. It is however cool to know that you CAN do it and you have actually DONE it!
The metaphor that everyone here is missing is the REASON he does this.
You ask yourself a serious question after you've done it:
What else can I do that I previously thought was impossible?
Yes, you understand the logic behind all of the firewalking. Just as much as you understand the logic that you can build a multi million dollar business if you do xyz.
None of it counts until you can actually flip that switch in your mind that makes you BELIEVE YOU CAN DO IT which then HOPEFULLY leads you to TAKE ACTION!
