I was watching one of those HGTV home buying shows. This lady needed to make sure that her property ($millions), as glorious as each one was, had enough size and location to construct a pit or platform for fire walking. She was a shaman or something.
I have seen many shows where the main criteria were enough yard for the dog to take a shit and run around, or maybe a garden for granny. I only watched one where the buyer wanted space so her clients would be able to walk through fire.
In some parts of the world, fire walking is part of a religious ritual associated with mystical powers of fakirs (love that name, but I must be mispronouncing it). They really do walk on burning coals. The lady buying the house really does do that. I could not stand to walk on coals that were room temperature or under water without shoes. Walking on burning coals has never been on my bucket list and it will not be.
In the USA this event has gone New Age as a self-empowering experience. Some see it as overcoming fears and phobias. This is not fake. People really do this. If you ever watched it, you probably noticed the brisk pace of the walker. They do not tarry in crossing. Nor do they want to fall. That is fire down below.
It is possible to walk on fire, or least on a bed of burning wood coals and not get burned. But burns do happen. The proper wood and charcoal must be used and the person building the fire needs to know what they are doing (shaking my head “no” as I wrote that).
I have no idea how this works physically or what psychological gain there is. But it’s physics: thermo dynamics, probably. And well-padded feet soles don’t hurt. Fire walking is neither magic nor magick, spirituality, religion, or some form of holiness. It is not the Universe blessing someone. But it’s also not fake.
