The original meaning of "achieving enlightenment"
Achieving enlightenment in Buddhism does not originally mean going to the afterlife or becoming a god-like being in a religious sense.
When you continue to meditate in the correct way, you will come to a moment when your mental state changes significantly.
As a result, you can see the world from a higher dimension than before, gaining mental freedom and stability.
The original meaning of the word "achieving enlightenment" is to reach the above-mentioned mental state through meditation.
