Loren,
Please do not forget my (first) question:
Are there two kinds of order, one with low information - crystal - and one with high information - biological? (As life seems to be highly ordered and have high information.)
Perhaps you answered it with the black hole comment, but that seems like an extreme example with inherent ambiguity, as you say depending on what theory you use. I would have to go with the "no hair" theory: as the black hole in my head is covered with less hair it has lower density of observable information.
I retired largely because of the stress. I did have the best students in my school system, and I do not regret the energy I invested in teaching, but I had to get away.
My '70s experience was that altered consciousness was interesting, but LSD had nothing to do with it if you want to live within it. I am not interested in religion, I am interested in life truths being self-revealed through right consciousness.
There may be "ten easy steps to meditation" or something, and everyone will find what they can imagine it is that they can. When I start, I would sit and wonder "why am I doing this?" and I went ahead on faith that all those yogis had to have something going on - it is not just relaxation. After some time and various experiences and more time, I have come to the conclusion that meditation is about unmediated mind consciousness. (Unmediated by language, for example.) When the mind directly cognizes itself, without circuiting through the senses, or whirling in thoughts, it spontaneously creates awareness of its own anentropic state. The effects seem to include awareness of the interconnectedness of all things (related to ontogeny recapitulating phylogeny), a sense of luminous well-being, fearlessness of death, and stuff like that. It is still not religion, it is just life! In fact some people seem to have related experiences in normal life. (For me it takes patience - concentrating on not concentrating doesn't always work.) Some talk about spiritual "energy", but I think it is not about energy, it is about the brain applying its natural task, finding structure and seeking relationships, to the object with the highest anentropy and the highest information of anything in the known universe, namely the human brain itself; but not through reasoning, rather through direct processing.
I have tried to ask other physicists if the model makes any sense in terms of physics, but I can't say that I have ever gotten as far as actually stating the full case - it is hard to even get started on such things around them.
