Merry Meet :)
I've never had a past life spell work, but I don't think it would hurt to try. Meditation is something that would definitely help, and I've heard that scrying can sometimes hold answers. Do some more research on gaining insight into your past lives, and then give it a go. :)
Some people don't believe in past lives, or don't think spells will work for that sort of thing, but do what you personally feel is best.
Blessed Be )O(
