Quora Question: If reincarnation were true, and in fact, we were all the same single soul living out every life throughout time, what then can truly be considered 'me'?

Tom Campbell is a Physicist who started doing consciousness research with Robert Monroe in the 1970's. He has written a book called My Big Toe (Theory of Everything), which you may find helpful.

In short, from my perspective, our "soul" animates many bodies thru time, and while it is a part of a larger "collective consciousness", like a drop in the ocean, it is also discrete. In the same way cells and organs make our bodies, and the cooperative inter-relationship of individuals and groups of individuals make the larger society, our individuated consciousness is both discrete and a component of a larger system.

There is no loss in being a part of something larger than ourselves, and the more aware we are of "the big picture", the less need there is to assign so much importance to what we think of as "me".
