The concept of past lives goes hand in hand with that of reincarnation, one of the more fanciful imaginings of the afterlife. Do we really get several chances here on Earth? Some of you will say yes, of course we do — we call certain people old souls for a reason, as we can sense that this isn’t their first go-round. Others find the idea too farfetched, even if it’s appealing to imagine that we’ve all been here before and have absorbed, on some cellular level, the lessons of our previous incarnations. We’ll probably never know for sure unless we all somehow get definitive proof in our next life.
