Source will present you with a past experience according to what you need to understand in that moment. What lessons are pending from before, what do you need to do better, who do you need to learn from, or to teach what. Understanding our past lives brings so much Peace to NOW. Thanks to learning mine I have been able to release old pains and redirect my energy into clearing those karmas and become better and better through working those traumas or mistakes. We are all here doing the same. If we had nothing to learn we wouldn't have been given the opportunity to come back to this planet. Earth is a school where we are supposed to Experience, to Expand, to Evolve, and to Enjoy. Polishing your teaching from your past lives will speed up your present process, you will know where to focus to achieve whatever it is that you need TODAY.
You can also have a specific question that might need us to dive into your past lives, lets explore together!
