If you do feel like you need healing, then going within will most likely help you to achieve it. Because it is not just that your brain has accumulated a lot of information over the time of your life, but it has also integrated all that information into knowledge, which is unfortunately only partly accessible to our conscious mind. The bulk of it is like the iceberg, immersed in the depths of our subconscious mind. We often call that part intuition.
So the amount of detail in our minds is much higher than we can reason with, and today's world does have this big cognitive overload that may make it even harder to focus on the essence of it all. Is it synchronicity that right this moment Sam Carter in Stargate SG-1 is talking to the utterly brilliant Daniel Jackson who was just found on a distant planet with no memory of who he was or where he came from?
That is pretty much how we come into this world as well: no memory but a definite desire to remember!
