You may be right... I am a bit CDO (see, they're all in alphabetical order now!) about some things, less so about others... and being in the outdoors is definitely a spiritual thing for me. It has been, ever since I was a kid and could talk to the trees... I keep trying to get that back... I'm almost there, but not quite... my daughter had it once too... maybe you lose it with age regardless; I don't know. Will have to talk to her about that sometime. She's 20 now.
Some of my "rituals" as you call them may simply be for comfort... One rather odd 'thing' I used to do on extended military deployments (back when I was in, 1984-1995) was eat literally the same MRE meal for weeks... I'd just kinda latch onto one and go for 3 weeks, maybe a little longer, 3 meals a day, same thing. Then I'd switch to another for a few weeks. At first I thought it was just that I didn't like the menu, but eventually figured out that it was for the stability... No matter what, I was going to have X for my next meal... I controlled that... not the Army, my boss, my subordinates, or the enemy... I decided what I was going to eat... makes sense to me now.
I also realized that my gear was always laid out exactly the same way... Slept with my back to a wall, boots, running shoes, and flip-flops under the cot in a certain order, clothing laid out the same way every evening, hat in the same place with the same pocket contents in it, flashlight hung up in exactly the same place, TP, mosquito repellent, tissues, earplugs, pistol, ammo, body armor, helmet, etc... all of it provided a sense of stability in a very unstable environment...
Some other things, however, fall into the spiritual realm... I think the way I actually set up my tarp... the knots I use and the orientation of the tarp, with its one reflective cord always in one particular corner... The fire setup, with how I lay in the firewood stock, sorted by size, etc... I think those things, which came about as a result of experience, practice, research, or were taught to me by another, which maybe fall under the category of "fieldcraft" or "woodcraft", those things might be more spiritual to me... they have real meaning... I know WHY I do them the way I do them, vs the other things from the previous paragraph, which, while there was purpose behind them, were more practical than nostalgic or spiritual, simply enabling me to react quickly to any situation in the dark, after being awakened from sleep...
Food for thought. thank you.
