Firewalking is ceremoniously used to show one’s physical and spiritual strength and to display courage, inner peace, and faith.
Often, it is used in other countries to commemorate miracles, take or fulfill vows, or honor the deceased, especially if they are saints or holy individuals.
Though initially puzzling, scientists say that there are several plausible causes behind the unburned feet of firewalker.
Some individuals believe that the speed at which the walker passes over the coals is related to their chances of being burned.
This would mean that those who rush over the coals are less likely to be burned, because they spend less time on the coals than others.
However, this is not necessarily true, as skilled firewalkers have been known to remain on the coals for upwards of thirty minutes without burns!
