If you meditate frequently, you might (should?) reach a state of enlightenment. This will take probably at least a year to reach.
I wrote that a year is a good upper bound.
After you have reached ‘enlightenment’, you likely still have to keep investing significant hours into meditation to prevent sliding back into the period of mental degradation.
I explicitly stated that enlightenment is permanent. I should also have explicitly stated that partial enlightenment is permanent (in the sense of not regressing to non-enlightenment or a lesser category of enlightenment).
You can’t describe to us what enlightenment is, how it works, or what benefits it brings.
I have provided a metaphor about how it works and described numerous potential benefits.
You have no empirically tested benefits of enlightenment to share with us.
My claims about the benefits of enlightenment are on the basis of empirical observation; you simply don’t have access to the evidence on which those benefits are claimed. I explicitly stated that too.
What do you think the causes of your mischaracterization of what I’ve written are?
I suggested 3 months to a year for achieving partial enlightenment.
If you consider seeing progress according to the four stage model that I gave (or another more detailed model) to be something that reduces the uncertainty of the value of the pursuit, then obviously you will be in a position to better evaluate whether it is a worthwhile pursuit much sooner than that.
