As opposed to achieving some fixed form of high wisdom, I think enlightenment is more the idea that insight comes on an as-needed, when-needed basis. And that it is not to be treated as currency, nor can one be materialistic with it.
This is my complaint with traditional religion. The idea that if you are a good boy, and save up all your good deeds [ideas] you get some sort of cumulative reward for being a good spiritual materialist.
Instead I’m leaning more toward the idea of seasons, timing, alignment of factors, instinct, intuition. I think intuition is the sum total of many instantaneous surges of enlightenment. They become imprinted on your being and are later there but not as intellect but more-so as intuition. They inform your choices which could be seen as enlightenment in action.
