Quote: 71.7 Questioner: Is the process in positive time/space identical with the process in negative time/space for this healing? Ra: I am Ra. The process in space/time of the forgiveness and acceptance is much like that in time/space in that the qualities of the process are analogous. However, while in space/time it is not possible to determine the course of events beyond the incarnation but only to correct present imbalances. In time/space, upon the other hand, it is not possible to correct any unbalanced actions but rather to perceive the imbalances and thusly forgive the self for that which is.I think the above quote is an excellent commentary on the properties of s/t and t/s.
The decisions then are made to set up the possibility/probabilities of correcting these imbalances in what you call future space/time experiences. The advantage of time/space is that of the fluidity of the grand overview. The advantage of space/time is that, working in darkness with a tiny candle, one may correct imbalances.
In s/t, we have the ability to move through space at our will, but not possible to do the same with time. In s/t, time moves through us, and hence, it is indeed metaphorically the 'river of time'.
In t/s, I think the situation reverses, with the entity being able to move through time, but held rooted to a point in space. Thus the entity can travel through time, but not through space. Probably, the past can be viewed along with probably the potential timelines created out of the choices made in hitherto previous incarnations.
All my opinion, based on that quote, only.
