Soul mate

[Minyatur]

Ok but there isn't a single entity which would be more complementary to you than any other and which would be your "soul mate".

I wouldn't necessarily say that. I will second Stranger's recommendation to read the Michael Newton books. It describes it perfectly. There are in fact souls that are more perfectly complementary to your soul than another.

Whether all souls have this is a good question.

So many things to read, I wonder if I'll ever be done.
