Enlightenment is a mysterious state that anyone can enter, even those who have never studied martial arts can enter this state.
A single moment of enlightenment can cause one to ascend in broad daylight. Although this is just an exaggerated myth, enlightenment is a profound mystery to one's self, but it brings about immediate progress.
The common man might attain enlightenment by understanding certain matters, but a martial artist's enlightenment is directed towards martial arts.
No matter what one's strength is, once one enters enlightenment, their understanding of martial arts will certainly be renewed and their strength will greatly increase.
Moreover, enlightenment has endless benefits for future martial arts cultivation, such as progress in learning various martial arts cultivation techniques much faster than others etc.
These are just some of the obvious benefits. Other things such as the enhancement of a martial artist's potential are invisible.
