Enlightenment is about the state of minds we occupy.
It can have real consequences to our actions, but it is my suspicion that the more genuine it is the less it will have.
Ofcourse, this can depend.
A person who is ‘normal’ will be leading a stable life, and so enlightenment shouldn’t really change that mode of life.
A person who is seriously troubled, living in an existential crisis, might have their day to day activities disrupted by their state of mind.
Achieving greater enlightenment may resolve some of these issues, causing them to act in a more stable manner.
The Bhagavad Gita has at times been described as the first recorded psychoanalytical therapy.
But when it comes right down to it the biggest thing that enlightenment changes is within ourselves, within our perspectives, not in the way we act.
According to several mystical traditions one form of enlightenment is to no longer see our true self as being our body, or the way we interact with the world. Pre-enlightenment we will take ourselves to be our body and think our self as directing this. Post-enlightenment we will no longer take ourselves to be our body, but the body will still be directed by the bodily inclinations.
Another form of enlightenment is to see our self as being one component in a greater whole, not much different to how our gut bacteria is a greater component in our bodily whole. To see the points at which we draw lines between different objects as being arbitrary (though created as a necesary reaction as part of an evolutionary process). In other words, seing our self as being the Universe in it’s entirety, and our consciousness as one little speck that has come to exist that is aware of this overall Universality. Such enlightenment could potentially lead to a form of fatalism in which no action is taken and the individual lies down on the ground in awed contemplation of what they truly are until they die. Eventually though, they will take action, because there is no reason not to.
When it comes to enlightenment being the development of perspectives, this will inevitably involve some change to mood. So while it may not directly inform action, it may indirectly alter the types of reaction that the individual experiences.
What is more, many people who have experienced some form of enlightenment will attempt to convey this to others. They might still chop wood and carry water, but they may also become a lay preacher for their own method and conclusions.
I think it is inevitable that many will do this, as when we find something we find amazing, we have an innate altruistic desire to gift others with an appreciation of it.
So, I would say enlightenment can heal and stabilise, it can instigate new ways of interacting with the world (e.g. meditation), and it can imbue a missionary spirit.
Personally, I enlightened myself out of existence, transcended transcendence, and the entity conveying this is somewhat akin to an answering machine message.
