There is a book (from channelling Seth) called "Oversoul Seven". (by Jane Roberts)

http://www.amazon.com/Oversoul-Seven...oversoul+seven


It's presented in a story format. For example, one of Oversoul Seven's personalities (individual fragment) Lydia is preparing to reincarnate into a baby in such and such time. Oversoul Seven is making preparations. It shows how Lydia and Oversoul Seven relate to each other. It also shows how Lydia relates to her own experiences of other reincarnations and such.

It also shows that a body/baby consciousness and Lydia's consciousness are different things and that Lydia can pop out of the "body" and put herself in other places.
