Many people believe in reincarnation. But doesn't that assume that time is linear and goes only in one direction? What if we are travelling backwards? If that is so, we can forget the idea that we are somehow 'paying the price' now for some error that we made in a previous life. We could be suffering for sins that we have yet to commit. How difficult do you want a situation in your emotional life to be? Avoid theories and beliefs. Stop worrying about things that you don't fully understand. Stick with what you know and trust.
