Hi there,
I’ve asked the same question. It has to do with learning the lessons and experiencing life in a human body. They tell me if we kept our knowledge it would hinder learning.
Have you heard of past life regression? I’ve never done it, but I’ve heard from some people who have, and they remember past lives. What I’ve learned is that the higher your vibration, the better chance you have of connecting with high guides, like I do, and remembering some of the soul knowledge we’ve forgotten. I do have flashes and feelings of knowing things from time to time, and I’m guessing more will come gradually.
Anyway, hope that answers your question. Thanks for asking.
Blessings to you!
