“Seth material” search engine (Jane Roberts)

You live in a world of root assumptions, to which all agree. They are the ground rules of your reality—but not the ground rules of all realities or of all probabilities. Your firewalker inserts another probability, and hence reacts to and with that reality of the fire in ways that are not considered normal. I have said his feet touch the ground but not the flames. Actually, what I can only call an invisible shield protects him from the flames, so that his feet and ankles are surrounded by an aura that repels the fire actively. This is a definite force, a psychic force field, if you will. This ability is quite ancient, though little known.

(9:59.) Give is a moment.... In very ancient times, medicine men had to perform such acts as part of their initiation ceremonies. I am not sure how to explain the process, however. The belief triggers body chemicals in a certain fashion, though the process itself involves an interaction between the air and the chemicals of the body, which form together a protective shield that repels the action of the fire.
