Note: I'm afraid I can't be bothered to provide full links today - if any of the terms are unfamiliar, and you are interested in finding out more, just use the Blogger word search facility in the top left corner of this page. Just to note this post is an extension of the idea of undulation.
1. The morning is the time for Primary Thinking - Final Participation. I rise at 5.30 typically; and if any time is going to be possible on a given day to attain this highest (and most divine) of consciousness states, then it is mornings: up until about 10.00 or so. That's when I do my best thinking, by far (assisted by note-taking, the notes generally being discarded soon after) - and when I sometimes feel consciously that I am thinking from my Real Self. This is the time for Intuition (coming from within).
2. From around noon to the evening I am in the mainstream, modern Consciousness Soul state - that is, I am conscious mainly of my-self and more-or-less feel cut off from the world, from other people. And the self I am conscious of is not the real-self but one or another of the superficial and functional selves, learned by interaction with experience, inculcated by The World.
3. In the evenings I tend to sink into the Original Participation - that is an un-conscious, passive state of immersion in The World. I may respond strongly to external situations, arts and people, but in a kind of trancelike and only semi-conscious sort of way. A somewhat 'shamanic' and imaginative state of affairs - and perhaps a time for Inspiration (coming from without).
4. Deep sleep is, of course, wholly passive and completely cut-off. There is no consciousness at all - it is a kind of vegetable life. This is absolutely necessary; but what really is going on, I don't know. To come-out from deep sleep is to feel its importance - clarified, refreshed, re-booted!
5. Dreaming sleep is conscious, but in another place altogether, and another time - a time in which vast amounts of experience may be compressed into very little time-as-measured-during-awakeness. This is a mostly passive consciousness, but in the 'underworld' (something like Jung's collective conscious, or the Ancient Egyptian 'dwat') - and it seems to provide necessary experiences that otherwise I would not have.
As dreaming sleep comes to an end, presumably having done its work, the dreams become repetitive and I then awaken; and it is best if I immediately get up and awaken fully. Dozing on beyond this point is boring, pointless; and sometimes leaves me too dulled ever to properly awaken the next day.
I seem to be stuck with this cycle of activity, purposive consciousness declining through the day, then the two types of sleep; and it is futile and indeed counter-productive to try and fight against it.
Best just to make the most of it...
