Information is streamed out into the universe and is freely accessible to all those who are tuned into it. In your mind is a great machine of data retrieval. It is a storehouse like the Akashic Records.
You house, in your spirit form (higher self), all your information - of all lives, dimensions and aspects of self. At night when you rest - you are able to go to your archives and crate and continue working with your aspects in other dimensions. Sometimes you are able to discover a portal within yourself that allows this information to bleed through to other dimensions.
