"Soul" as the decision algorithm

This is a rough sketch but it seems to work.

The "soul" is the decision algorithm. The reaction from circumstances.

It is not the body-mind.

It is not the memory.

And the "soul" that inhabits the body-mind can be changed.

It is the invariant in the "what would I do in these circumstances?" kind of thinking.  If two things react the same way given the same circumstances, it must then be the same identical thing.

The question is how much auxiliary memory does the "soul" possess and why does it have such memory? 

This idea must be further explored and consolidated.

------

Note that people tend to identify with their memory and life experiences, which apparently the "soul" is not quite that thing. People tend to regret, but their soul-as-decision-algorithm is hardly changed, with the only notable difference being the availability of hindsight. That sort of regret is meaningless.

It seems that changing one's decision algorithm does make a difference though, and apparently such change is spiritually profound and is potent for righting wrongs.

This idea must also be further explored and consolidated.
