A liminal space does not have to be a void, though it can be. You can fill it with what you want. You can plant seeds in potted soil and carry them with you when you go. You can litter the space with so many of the things that have been holding you captive and simply leave them behind when you leave. A liminal space does not have to be a purgatory. It can be exactly what you make of it, because it is not a void-- it is filled with all of the potential of what you need it to be.
