My thoughts on past lives:

The importance past lives have, comes to relevance in the here now moment by moment unfolding. The present is where we are expressing, and therefore the present is the point of power, where we can consciously make choices about things we may have previously just followed the stream of consciousness without giving thought or attention to whether that promoted our well-being or not.
The present moment is always right here, right now, and whatever this right here, right now holds for each of us is what we have to deal with. It is far less important to know it originated in the past. It is far more important how we deal with it, what our chooses are in this moment by moment unfolding, and these choices spawn the next steps upon our life path journey.  And, whatever these choices are, they either balance the energies associated with them, or further create imbalances which cause the issues to recycle in our life expressing until we balance the energies associated with those choices.
