Enlightenment is not one single gateway or light passage.
There isn't a moment when your spiritual evolution stops.
Imagine when you travel by plane.
The thrill and excitement has to do with take off's acceleration.
Once you reach a cruise speed, everything feels normal again even though you are traveling very fast.
In my experience, there isn't a one time enlightenment stage, rather a succession of key accelerations which bring you closer to universal awareness.
