How interesting though that you say that her prejudice kept you alive! Did your mother tell you this story? She admitted to it?! What a story! It sounds to me like there's some real karma being worked-out in this situation.
My aunt harbors a lot of racial prejudice, however loves black people. She has been saying for years that she was black in a past life. I guess I find it interesting what issues we carry from one lifetime to another. I'm sure it's possible that we've reincarnated in many different cultures, however only certain ideas, prejudices carry over.
