Here is the thread being referred to. viewtopic.php?f=13&t=2798&p=4076&hilit=thynes+guides#p4076
Tom did not exactly say they were 'asleep'. Sleep is PMR, not NPMR. Inattentive is a different thing.
As has been said, you simply cannot take everything as fixed in the way that you might think here in PMR. Do not think of a guide to be someone hired to be your nanny. Yes, individual IUOCs in NPMR function as guides and there is always a shortage. No they do no oversee our every move and thought. Yes there is guidance that is not specific to a guide as an individual entity. Things are 'fluid' and as Tom says, guidance can be 'bubbled up' out of that 'fluidity'. Consciousness exists everywhere in the LCS. The Big Computer that is referred to as creating our PMR VR probabilistically and then as we experience it via its VRRE function is not like a great big super computer of here in PMR. TBC is also 'intelligent' and conscious. It follows a program but it does not just follow a program as a PMR super computer would do.
The model is a model to give us handles to 'get hold of' our PMR experience. It is very much like how things work most of the time and and in most ways, but it is not exactly like how things work and does not completely describe things. Without Tom's model, we would just be churning in confusion. Once you understand it however, you kind of let go of every little detail and realize where there is more to it than in 'just' the model.
It is like higher education in graduate school. You learn details, most of which you should have learned at lower levels. But the real purpose is to learn how to think within your particular field, what is significant, what matters within your particular field, what matters in intellectual pursuits in general, how do you contribute new knowledge to your field and in general, how to evaluate things and apply effective criteria to hypotheses to evaluate their credibility and value.
We must in general live with uncertainty. Learn to do it gracefully.
