What Is the Thing Under the Door Called?
The thing under the door is called a threshold. It is the point at which you cross from one place to another, or from one state of being to another.
It is a place of transition, and as such, it can be a place of great power. A threshold can be a physical place, like the door to a room, or it can be an invisible line that you cross in your mind.
Either way, it is a place where something changes. When you cross a threshold, you leave one thing behind and enter into another. The power of a threshold comes from its ability to change you.
As you cross it, you are no longer the same person you were before. You are transformed by the experience. A threshold can be a positive or negative experience.
It can be a place of great joy or great sorrow. It can be a place of new beginnings or of endings. But no matter what, it will always be a place of change.
So what is the thing under the door called? It is called a threshold. And it is a powerful place.
