I would like to add that some cultures have no words for enlightenment except those borrowed from other languages and then been modified to fit the cultures native language. The native Sami people that live on the north parts of Finland, Sweden and Norway refer instead of enlightment to a word which could be translated into a something as a journey to nowhere. Their shamans think that instead of a single instant change of mind there is a continous journey to realizing that there is no something that would be translated as a subject or me. The continuous journey leads ultimately to a unexistence of ones self and that is the part they became whole with the tribe.
Some come to an end of that journey in their childhood, some when they turn teenagers, some as adults and they ultimately believe that if you havent gone through your journey before die, that is the last time you are going to realize it.
They think that as the subject or me becomes obsolete during the journey then the body can unify with others and cross the barriers what others that havent reached to the end of their journey as a difference of living and death, animate and unanimate. Those who had made their journey cannot anymore differ those from the other. Rocks are same as people, trees are same as people. The sun and the rest of stars are same a the people. They leave their dualistic views behind and instead of being a person they are the whole world around them.
But what the hell, they drink pee from reindeers that have have feed with otherwise toxic mushrooms to get to a trabce state. I wonder how they came up to that idea that the mushrooms that exists where they live are deadly if eaten not depending how they are treated, one mushroom can kill your liver and also result in kidney failure. But when those are feed to the reindeer the reindeers metabolism (or a first liver pass) are not harmful to them and they excreet the hallucinogens of the mushrooms to their urine which is then no longer hepatoxic.
We Finns do not either have a word for enlightment that does not came from other languages. The borrowed word would actually mean someone having a vision and instantly changing their live and view of world. We do have two indigenous words that also explain the phenomena as a journey as the Sami people. Other one means when translated in english as learning to live. Learning to live leads to a same situation as the Sami peoples journey where you notice that there is no you bu instead everything. Tho other means being aware and being aware means that you notice that there are other subjects around you and you interact with them co-operatively but maintain your ownself instead of killing your ego.
I think that I am somewhat being aware but still also on a journey too but I am afraid of killing my ego. I do also feel connected to the world around me in a sense of new knowledge that we consists only of matter which is omnipresent everywhere in our endless universe and therefore I am not better than rest of beings that have the ability to sense the world around them. And ultimately matter equals energy so we all part of the born of the universe and the energy released upon that time in the form of radiation which then become into soup of atoms which gathered into formations because the soup was not totally smooth and caused the first stars to form abd release other heavier atoms after they died. Also the formation of galaxies, clusters of galaxies, black holes, etc and finally into a solar systems which could become habitable by a differeny forms of life and eventually into a species that try to think about the existence of everything.
Even though there is no dualism and our ideas are simply energy and matter doing their dance in our brains, we must understand that we have concepts that are here to help us to cope in this non-dualist world. Think them as a tools. If you would have a baby you would have concept of baby even though the baby is only material which can be also energy. But in order to cope with our existence with our bodies that have outdated as our minds have grown into a different levels faster than the body. And therefore we need to be also able to think ourselfs as a subjects to make that baby survive by giving him nutrition, shelter, ways to explore the world and start its journey and the process of being aware.
This just the conclusion where I have ended on my journey and I am not finished which means that I am open to new ideas instead of just building a wall around selfexistence and blocking out every opinions out.
I think that the enlightenment as you think can be reached through continuous learning and becaming more and more aware of the world instead of a heavenly strike that changes your mind in milliseconds or that it can be only gained by using psychedelic drugs. Psychedelics might help people that have no time to meditate or otherwose are being hesotant to a change in their views but in my opinion they are not needed to gain enlightenment as I see it through my cultural background which affects a lot as we are not so christian country even though most of us belong to evangelic-lutherian church which is a protestant church but it is more because the tradition than the true beliefs. We are mostlt pagans which happens because we are more connected to the wilderness (chaos of nature) than the cities (build to defeat the chaos of nature). Check out the way I used the word nature as there is only nature and nothing can be unnatural, we just tend to tinker with natures normal chaos form to lead it up in more constant environment such as villages and cities.
And as we live close to the chaos, there starts a forest from my backyard, we always remember the chaotical form of nature and tend not to develop irrelevant dualistic idea consisting of natural or unnatural and therefore we think LHC and particles created with it as natural as a tree that grows in our backyard and does it leaves. Therefore we have no problem using drugs synthesized from materials occurring in more or less chaotic nature. And everyone thinks that using oxycodonr is as natural as using weed. The other one just have to been uniformed more from chaos than the other.
Shoot me if you want but these are just my opinions which can be changed if better solutions arrive.
