Think about it. As an analogy, consider your self as existing in the typical mad scientist scenario as being a brain floating in a jar of nutrient fluid. Into the jar goes a single connection like a very broad band 'cable' connection comprising television, Internet and telephone plus a step beyond as 'the feelies'. Over that connection comes all of your external interactions and out goes all of your thoughts and decisions. There is no incoming line for the nutrient fluid, it just 'is', and there is no 'plumbing' for waste to leave. The 'fluid' provides everything that you require to exist, energy to function, other than the data feed. Actually, it is a pretty good analogy, although an impossibility in PMR. The fluid is the 'reality cell' substrate, that Tom describes, which also constitutes your own being. The only thing that demarcates between 'you' and 'not you' is the nature of the data stored there. Accessible to you internally and part of your functioning 'digital neurology' or not accessible to 'you' within your 'digital mind' which is your total self, all there is of you.
From this state, all of your experiences are generated based upon incoming data that you interpret within your brain/mind inside the jar. You interact via this same 'cable', serving as your outgoing data link as well, your connection on the RWW. You are not 'in the dark' nor are you 'alone'. Such concepts have no meaning, just like not having within PMR a second brain that is someone else within your skull or having 'eyes' within your brain where there is nothing such as light in existence. The incoming 'cable' signal switches extremely fast between several different signals, representing your PMR(s) and NPMR(s) that you experience and also any direct functioning which you perform as a functional computing node, shall we call it, as part of The One Consciousness. For purposes of modeling, we consider this switching to take place at the fundamental 'time quanta' or 'delta t' of the experience represented by each separate signal. We are 'co processing' these experiences. We switch from one to the other serially, or sequentially. But the switching occurs at such a fast rate compared to our conscious perception that we consider this to be 'parallel' experience. We do not actually know if there is a more complex interweaving of signals than this, but for the sake of simplicity in modeling, applying Occam's Razor, we think of it in this way. It will make no difference to ourselves in our perceptions, being below the 'quantum time' level possible for that experience stream.
We have no way to know what our 'function' is within The One. We may exist to provide the N'th digit of Pi when it is required, although that could be supplied by a simpler consciousness, a dimmer bulb, than we represent. We might be the one providing 'the secret of life, the universe and everything' per Douglas Adams (or however he precisely phrased it). More likely, something in between these levels of complexity. What we are 'conscious' of at this level of functioning, I certainly do not know, nor can I think of any reason to need to know. I believe that we have conscious experiences and interchanges of data, interactions, that are not mediated by a virtual reality interface, but I am not personally aware of the nature of such from here in PMR. This could only meaningfully occur with the limited number of IUOCs that function as closely to us in terms of experience and interpretive model to communicate meaningfully. That is, we have a low enough entropy level to communicate without the 'template' provided by a VR.
Now for some reason, some of you wish to contemplate the ending of this ongoing experience and the data collection and 'neural network' that is yourself in total. This would mean that you wish to terminate your usefulness to The One and each and every one of your VR experience streams plus any direct interactions you have external to a VR interface with another IUOC. I think that this is an unlikely situation. This would mean that your experience in every 'channel' within which you participate was so deadly or dreary or whatever that in all 'channels' you wish to stop the experience. You have someone(s) at a 'higher' level, guides, looking over your experiences that should notice the negative trend and recommend some different experience packets or new NPMR assignment as needed to 'brighten' your outlook. The 'System' wants you to succeed, to lower your entropy level and improve the 'quality' of your consciousness. That is why this whole Consciousness Fractal exists and 'self creates' itself as The One/AUM. That is the whole purpose of existing in the way that it does. All for one and One for all like the musketeers in the novels. So what precisely is your problem, d'Artagnan?
To end yourself when there are no hands, not to mention razors, rivers, drugs or poisons, per Dorothy Parker's litany, is a difficult matter. You could cease to willingly communicate over those communication channels that you control with your Intent. But that takes a very bad quality of your Intent to do so. That does not mean that you do not have other channels that are not at your control and would still continue. You exist to experience consciousness and to interpret data. Shutting off the flow probably has the same results as someone in PMR in a sensory deprivation tank experiences. You start to make up your own data and become irrational. Will that be an improvement, a cure, for your 'cosmic depression'? Can you request the sending of a 'euthanasia' data stream that will return your 'circuits' to a 'new' and blank or minimal, disorganized state from which you must start the training from PMR experience packets all over again? That would definitely happen as the resources represented by your existence would not be permitted to remain unused. Does this seem likely to you? You can re format a computer's hard drive to a blank state, but you were not self bootstrapped in that way.
Tom will have to take it beyond this point.
