Were you aware that all souls have a soul record? It is called the Akashic Record. The Akashic Record records all experience a soul has ever had, positive and negative experiences. As humans we experience our lives with mental and emotional energies attached to our experiences leading us to certain perceptions, which help to create our Judgments and belief systems.
Having our negative programming cleared educates our souls as to why we developed a negative experience, helps us on a soul level change our perceptions and beliefs and therefore frees us from carrying that negativity around with us in our current life experience. For some people this process can be a life changing experience.
