The Akasha can be understood as the ether. It is quite an esoteric concept, shared by many ancient cultures, and is heavily referenced in Vedic texts. In short, the Akasha is the realm that holds our collective history it is full entirety. It's like the collective memory, in metaphysical library form, of our dimension
So, how does this work? How does information find it's way to the Akasha?
In the spiritual world, it's well accepted that thoughts are energy. Energy can never be killed or destroyed, it just changes form. When we have a thought, a memory, an experience, an idea, what happens after it passes through us? Energetically, they must go somewhere right? While this energy can imprint our DNA, the crystals, rocks and plants around us, the water that flows, the entity of the thought goes on to exist in the Akasha.
The Akashic Records are the books of every soul, every life, every experience that has ever existed. We each have our own book, which captures every detail of our present, past and future lives. To access this book, you visit the "Great Hall" through a meditative state. There are keepers (masters), librarian souls who facilitate access - you are only permitted access to your records if you have the highest intentions of good. You can consult your book to learn about your soul - it's mission, karmic lessons, and past life influences. You can for guidance about challenges in your present life, or things you soul wants you to focus on right now. Or, you can explore how things work in the 3d world (and beyond).
When these questions are asked, who answers?
Well, I believe it's my Higher Self, or soul, with communication facilitated by my spirit team and the Masters of the Records. Since I believe that time is not linear, that the future and past exist in the present, it's only sensible that my soul would know everything that happens in my past, present and future, whether it's this life where I'm Natalie, or others. And, since this Hall also contains the realities of every other soul in our 3D realm, it is possible to "look up" information relating to things "outside" myself, outside my book. This is where the Masters assist.
