Sounds like you read the secret and put it in your book, only changed the secret into the dance, or song, or were you the one to write this first? Either way one of you should sue, maybe they should see your book to get ideas for their next book. I will send them a copy. Mind you I only read the limited preview, but certainly sounds like the secret to me.
Also, I will send you Tango: Dange of Self-Discovery to Oprah's book of the month club, maybe you will get on her television show. She sure liked the secret.
