The 6 days are the 6 energy centers, the sixth reached before the light breaks open, the lower labor of the body completed step by step until the ascent can begin. Peter, James, and John are the 3 levels a person carries up together: the physical, the mind, and the spirit, with Peter the small stone, the pineal, the seed of vision at the center of the head. Led apart, away from the crowd of ordinary thought, they climb.
The high mountain is the raised state of consciousness at the crown, and there the form changes: the hidden radiance that was always inside the body shines out through it. Transfiguration is the light that lived within a person breaking through the surface once the climb reaches the top of the head.
