Is it possible to rid yourself of bad memories? According to spiritual teacher Eckhart Tolle, author of A New Earth and The Power of Now, it all depends on how you approach those memories. If you recognize that a bad memory is just a type of thought that pops up in your mind, you don't need to identify with it any longer, he says. 'Super Soul Sunday' airs Sundays at 11 a.m. ET/PT on OWN.
