When I was working on my novel Redemption, I knew nothing about past life regression. So, in order to send my main character to past lives, I first came up with a fortune teller, who later turned into a psychic.
That was a long time ago, and I have since learned that there is a method that uses hypnosis to extract memories from past lives - past life regression. So the correct "name" of my fortune teller is a therapist :).
I also found the Past LifeRegression Meditation by Brian Weiss. Although I myself have not yet been able to look into my past, I have noticed that many people have made progress. Please find the meditation video below.
It's fun even if you fall asleep in the middle! 😉
I also found an interesting website full of information about past life regression.
