"liz but if children do choose their parents (think Lorna Byrne also said this) how come some choose abusive ones? That's always confused me!"
Me too. I've read that it's something to do with souls needing to live the entire "range" of human existences, to be both the abuser and the abused, to experience the extremes of human emotion i.e. joy to despair etc. NOTHING at all to do with any sort of "punishment", but in order for the soul to progress and evolve by learning through our multiple and varied human experiences. Of course, we're not aware of this while we're confined to the limits of whichever mortal human life we're currently experiencing, apart from these "blips" such as the children who come out with the most astonishing (to us) declarations as we've read on this post.
Again, it's a difficult concept to wrap ones head round. But part of experiencing a human life is being limited in our understanding, I guess.
