At its most basic the labyrinth is a metaphor for life's journey.
The labyrinth is not a maze. There are no tricks to it and no dead ends. It has a single circuitous path that winds its way into the center. The person walking it uses the same path to return from the center and the entrance then becomes the exit. The path is in full view, which allows a person to be quiet and focus internally.
Generally there are three stages to the walk: releasing on the way in, receiving in the center and returning when you follow the return path back out of the labyrinth. Symbolically, and sometimes actually, you are taking back out into the world that which you have received.
There is no right way or wrong way to walk a labyrinth. Use the labyrinth in any way that meets what you need while being respectful of others walking.
