Emotion, intellect, and body go bound into the burning together, and what the king counted as 3 walks unharmed because the fire is spirit, not destruction. The chains are what catch and dissolve; the faculties they held do not. When the passions blaze at their fiercest, the part of a person that stays untouched is exactly the part no rope reaches, and the astonishment is the moment the outer self sees that the binding, not the man, was consumed.
The counselors confirm 3 were cast in, yet the fire keeps returning them whole. Spirit meets the flame and puts out its power to harm, so what looked like ruin turns out to loosen a person instead.
Fire: the spirit, the living flame that consumes only what binds and cannot destroy the self it touches
The 3 bound men: emotion, intellect, and the physical body, the working faculties carried into the blaze
