The method I use, created by Dolores Cannon, is a safe and profound way of not only doing past life regressions but also involves contacting and receiving guidance from the person's Higher Self.
The sessions are long... sometimes 4 hours, but the time flies by due to how interesting they are.
I don't know how each session will ultimately unfold. That's up to a higher intelligence than mine. I do know, however, that the individual going through the process will leave with a better understanding of who they were, who they are, and who they may become.
And in these times of uncertainty that is a beautiful thing.
