>Fig. #1. When dealing with alter-realities, there is a cross-over, a trickle down/up between levels. This often creates a small hardship toward understanding--the hardship comes because there is no clear title that can be used when having reference to the repetition of the same body under the influence of different levels. Because of this trickle down/up, there is an overlap between levels with respect to the Ka in question. Care must be taken if understanding is desired. In Fig. #1's level one, it is the Ka that goes to sleep; and, it is level one's Ba that becomes level two's Ka. Again, it is level two's Ba that becomes level three's Ka. Again, it is level three's Ba that becomes level four's Ka. Notice that it is always the Ba of a level that goes traveling; it is never the Ka of the level in question. This is because the Ka of any level can only travel through the physical space of its home level, while the Ba of any given level can travel through both, the time and the space of any other level.
