The method I use to take you to your past lives is the same as the one advocated by Michael Newton. Newton was a psychologist and hypnotherapist who developed a protocol to enable clients to visit their past lives and the place between lives. He saw thousands of clients over many years and trained other hypnotherapists in his techniques. He founded the Michael Newton Institute which still trains therapists in his methods today.
Michael Newton has written many books on the subject of past lives including:
Journey of Souls
Destiny of Souls
Life Between Lives
Memories of the Afterlife.
I highly recommend reading these books to understand more about past lives regression therapy.
We all wonder what our purpose is on Earth and where we will go after death. Through past lives therapy you can find out through hypnosis the answers to these questions. Not only can you see your past lives but you can also visit the spirit world and find out what happens to souls in between lives.
