The basic premise that women and men look at the world differently is true. His past involvement with TM and his claim that he spent so many years celebate that sperm seeped out of him from his sweat glands make him sound a little nuts to me.
He was married to a woman that has also made a bundle selling books about relationships. ( Beverly DiAngelus, I most likely mispelled her name )
They could not make their relationship work so they divorced. I always thought it was funny that they were both so successful, but as Steve Forbes grandfather said,"You don't get rich by taking your own advice, you get rich by selling it to others."
