The Aondor Is a Like Energy That's Accessing the Physical Realm

Aondor is described as a like energy that's accessing the physical realm in specific pulse lengths or frequencies. So i would assume that the sheod or reod both, whatever that event is, is changing their spiritual diane and that's why they can still access it. Acasan is sort of another version of accessing the door on cell. Its practice by a meditative martial arts, a style that seems to be used on quick motions and somehow gaining power from those motions. And it's used by the gindu. Who are the gindu?
