Some of the first scientific experiments done in psychology involved the measurement of perceptual thresholds. The example I will invoke here is the measurement of quantities of light: how many lumens do you have to increase a stimulus in order for the person to perceive it? This was measured across numerous people in numerous studies and numerous conditions.
What I would suggest is we live in a sea of light. As I have often repeated, Richard Feynman–who I will note was seemingly an atheist, but I would guess more out of habit than philosophical conviction, as I think it was just not a “problem” that interested him–said that every square meter of “empty” space contains enough latent energy to boil every ocean on Earth.
“Enlightenment”, so called, is a gradual process of seeing the next gradation of light, which happens gradually, but is perceived suddenly. It is quantized, from a perceptual perspective.
I have long been dissatisfied with Zen stories, where some seeker encounters some particular stimulus, and becomes “enlightened”. A made up but representative example might be “a twig then broke, and Kobayashi become enlightened.”
There are many enlightenments, in my view. The process is becoming more and more aware, and I think there is a certain point where, relative to this world, you achieve neutral buoyancy. You can go up and down with equal ease, where until that moment you were weighted down by an ignorance of what was possible.
We are all nomads, if we believe that when we die we travel “on”, in Dumbledore’s (Joanne Rowling’s) memorable phrase. We have no home but here. No purpose but being present.
And of course all of us exist within cognitive and purposive structures. On this planet we have to physically survive. We have needs which are often hard to meet–for food, for love, for companionship, for shelter (emotionally and physically). This is all part of it.
You never become one thing and not the other. The Buddha ate food. He decided each morning what to do with at least the first hour, and perhaps he planned weeks in advance at times. He had a Life Purpose first of achieving neutral buoyancy, then teaching others how to, possibly, do it themselves.
And he taught his followers to be nomads. Perhaps that is good and even necessary practice.
And what I feel is that each of us tends to want a nest to live within. We have a floor and we have a ceiling, in terms of what we allow ourselves to perceive.
But I think the large feelings–the traditional Four Greats are joy, peace, love and compassion–require room to circulate. Despair is very likely connected to joy. There is a loop which would go below our floor, then rise above our ceiling. If it is reliably stopped in both directions, it cannot circulate, and cannot become a part of our experience.
Perhaps peace depends on familiarity with terror and anxiety.
Perhaps love depends on the capacity to hate.
Perhaps compassion depends on the capacity for complete indifference.
All of them, perhaps are loops. And if we allow the loops to complete, we can CHOOSE what we emphasize, but the momentum will be UP, towards the higher sentiments.
And open space, of course, allows it all.
Oh, so much is possible in this world. It all starts with the courage to try, to seek, to risk, to fail, to endure confusion, heartache, pain, sadness, anger, and all the rest, and through all of it to remain open.
Openness is raising your roof, and lowering your floor, until both are far away, and perhaps one day vanish entirely.
Wherever you are, this will be invisible to those around you. They will merely see the effects, if they have any power of perception at all.
