For a message to be understood from any source of information, first you must have the algorithm/filter to uncompress, translate or understand it. You must have a pre-defined understanding, like know the language, or the symbol set used, in order interpret the reality in front of you in the right context.
For the full understanding to arise you must uncompress the concept held in the words, symbols or data
The Buddha talks of nirvana as an uncompressed reality, and a unity of all consciousness. The Buddha obtained this state is by shutting down the external Inputs and Outputs to your consciousness. Block out all the data that is possible coming in to be processed. Once that is achieved, starts to look for something else to process. It works over its backlog of thoughts and starts to bring things to the surface.
The Buddha would then start to shut down the internal Inputs/Outputs’ between the minds internal systems. Not identify with any of the thoughts, see each arising and departing separately. The internal thought filters that you use start to fall away, and you start to get a sense of the whole system as one thing.
Perhaps this nirvana is seeing the whole stream of data as one indefinable chunk. Of not labeling internal or external, of just living a pure, undifferentiated, unlabelled experience (or at least having a living comprehension of this idea). An un-compressed, unfiltered view of reality.
