the object of change of space processing is to get all areas into present time. Originally it could be conceived that only the place where the preclear is is in present time, that all other places are in past time to the degree that they are far from the preclear. Change of space processing is done in this fashion: "Be at the place where you entered the mest universe," "Be at the center of this room," "Be at the place where you entered the mest universe," "Center of this room,"
"Entrance point," "Room" and so forth until the entrance point is in present time. The preclear should be made to run change of space on any area until that area is in present time. (COHA, p. 38)
