How do I explain this in regular-people-speak? There is a widely accepted theory that there is a vibrational record of every thought and action by every soul, in every lifetime they’ve ever lived called the Akashic Records. That’s how I understand it anyway.
The records are accessible to anyone and you can go back to any time in your soul’s journey to understand and get insight into concerns you have about your spiritual path, your life purpose, your family, your issues with money, etc.
You can’t just walk to your local library and ask the librarian to hand over your records, but it’s something like that. You just have to get to the alternate dimension of consciousness and ask for directions.
