Look up, there, at the highest branch of the nearest, tallest pine tree. See the needles at the end of that branch? Those needles are composed of a collection of molecules that, if traced back in time tens of thousands of years, might have flowed through the cardiac system of an ancient ancestor of a deer who lives, today, in those woods. Or they might have struggled, as components of a sapling, to rise above the forest floor. Some of those molecules could have been nestled comfortably inside a pebble submerged in a seasonal creek that no longer exists…but every element of those pebbles…and the water in that creek…and all the leaves and needles in the forest…and everything else, seen and unseen…still exists today. Even the pine borer beetles and the bright red plumage on the pileated woodpeckers and the fresh urine of the coyote cubs wandering the landscape today carry elements of those long-gone expressions of the natural world of a time long gone. Imagine tracing every moment of the existence of a single atom, back to its origin. It boggles the mind.

Do sound waves disappear? If so, where do they go? What transformations take place, between the moment a bell rings and the instant the sound waves no longer register in the ears and brains of a person five hundred feet away from the bell? Light travels billions of miles between its source and its detection in galaxies at the edge of the universe. Do light waves eventually stop moving across space and emptiness? What happens to light when the energy propelling it fades? We may have logical answers to those questions, but are the answers based in reality, or only in the complex minds of people who claim comprehensive knowledge of the laws of physics? Everything we know and all our experiences may be the products of a single mind’s imagination. Trees and pebbles and woodpeckers and people and pine borer beetles do not exist in reality; they are just ideas spawned by one individual…who could be a person or a saguaro cactus or a drop of ocean water…all of which also are just concepts, not physical objects. Imagine that; an imaginary being imagining a limitless number of other imaginary beings that also imagine an endless supply of additional imaginary beings. Rational thought, conjured by irrational minds created by artificial ideas. We trick ourselves into believing we are real, when in fact we have no substance outside our own vaporous existence—which lacks substance because it is not there, except in theories hatched by ideas that pretend to exist.

None of this represents my actual thinking, of course. Because thinking is an idea that some would say lacks physical substance. These are the sorts of mental intrusions that make it impossible to achieve a state of relaxation. At least for me. We cannot get a grip on reality if reality does not exist, right? If logic and knowledge are no more than temporary diversions from a tangled form of chaos that is growing exponentially, then logic and knowledge could be pointless respites from something we cannot define, cannot measure, and cannot explain.

I need rest. I want sleep. I would value six consecutive weeks of restorative unconsciousness; give or take a month or two.
