Have you lived other lives?  Of course.  You may find it fascinating to delve into those lives.  What do they have to teach you?  They teach you what you have chosen to work on as a soul in those other lifestreams.  Worry not if they are past, future, or parallel lives.  What matters is that the soul is experiencing possibilities in those lifestreams, leaving certain possibilities to experience, work on, learn here and now.  If you identify certain other lives and certain repetitive patterns, then perhaps it is time to be done with those patterns here and now.  Perhaps it is time to balance out the scales and continue fleshing out the fullness of the soul, which you do by embodying flesh for a while.  Do you see?  Embrace here and now as a soul in the flesh who has come to this moment in time and in space for the experiences, the growth and the learning that this very particular lifestream has to offer you.  You are who you are and how you are for a reason.  Embrace it and grow!
