Path.
An abstract concept that held enough weight to decide one's life. An intangible meaning that symbolized the whole to some people.
In the eyes of mortals, it was a direction, a physical route that they use for their daily activities.
However, to cultivators, a path represented their future. It signified their destiny. It was their identity! Their past, present, and future!
At a certain stage in life, just like mortal youth, cultivators would have to choose their path.
They would stop at the periphery of multiple potential paths and choose one. One main path for them to traverse.
This periphery was in between [Realm 2] and [Realm 3]. Those who had already known their paths would have added an attribute to their energy.
That was the condition for the hidden stage of [Realm 2].
Jake had achieved that when he had gained insight into his path.
