Neville Goddard constantly talked about this. He called it "Revision". It is the forgiveness of sins. One example he gave was of an old woman who had lived her whole life with back pain due to a childhood injury. She used his technique to relive the moment without the accident. The pain went away.
I'm currently testing this technique to change my height. I remember a time in my late teens when I was measured and I insert the height I want into the memory.
Neville's explanation is that man is a four dimensional being. That is, his past and future exist at once. His future is pre-determined by this. Man can alter his future or past by the time travelling mechanism known as "imagination", in which he changes himself to transform the pre-determined future or past. He teaches people how to focus away from the senses and into the imagination to focus its power. Neville is a billion times clearer, more practical and more inspiring than Seth. Try him.
