In reply to my post, Mapping Your Life’s Journey, I got a really interesting email from my friend Jonathan Harris, the cool artist whose work is as fascinating as this note:
There is a centuries-old idea coming from the Hindu tradition, of "The Akashic Record", which is said to be metaphysical plane where all information is stored — every thought, action, interaction, and idea that has ever occurred. A kind of cosmic filing system.
There is debate over whether The Akashic Record is already completely written (and we simply follow it, like actors following a script), or whether it gets updated every instant with new information (and free will exists).
It is believed that when we dream, we access the Akashic Record, and that this is why dreams often contain either future prophecies, or seemingly random events from long ago that haven’t been thought of for years (because in the Akashic Record, all things are equally simple to access, like searching on Google, or, perhaps more appropriately to dreams, clicking "random page").
It is also believed that tapping into the Akashic Record is our source of energy, and that this is why our bodies need REM sleep to function (REM sleep being the time we access this record).
Whether you believe in this stuff or not, I agree with Daniel that we are fast approaching a time when our technology will essentially create the Akashic Record for us. You could say that this will happen in "another dimension", as the meta-layer of aggregate online information could be considered as such.
I am very interested in seeing this happen, and believe that it will (if the world doesn’t end first, that is).
