Please allow me to comment one more... this may be different from law of attraction itself, but well, a bit related since it mentioned the carnation theory a little. (In Hickily books, probably I misspelled, sorry)
What if you lived on this earth 1000s of times already? What if a person decides and says, "hey this time I want to try and live a very disturbing childhood and see if I can rebound in the later life!"? One of the people who preach Spirituailty, said, "Thanks to those people who kill you, you get to understand what it is like to get killed."
...Maybe a bit disturbing. Sorry if it disturbed you.
