In Gestalt view a liminal space is a place of transition, you are leaving something behind but have not yet arrived somewhere else. The space between a gestalt being completed and a new gestalt beginning to form in the fertile void between gestalts.
In such a place we might experience a sense of being on the edge of something,

Physical spaces are liminal space: the door to a new room,
the rolling stairway that connects 2 different levels of a building, the waiting room at the doctors.

The artist and the writer encounter liminal spaces when the sit at the margin
between intention, inspiration, the vision that they have for their piece and the actual form that starts coming together as they progress with their work

In therapy, I encounter liminal spaces when the client and I are meeting in a moment of reflection that opens a new way of seeing, a new experience.
That pause where no-thing happens, where I pause and the client feels what it is
Allowing themselves to be with both what was and with the potential of newness.
This stemming up defines the next move, the new form and a new experience.

What liminal space did you recently sat in, intentionally?
What liminal space you landed in, unintentionally?
And how the two feel for you?
