The concepts you listed all have in common that they involve a space or point of transition, separation, or connection. They also involve the potential for change or transformation, and the presence of unity or diversity. The gap can be seen as a space or point that exists between or among different things, and it can serve as a boundary or transition point between different states or conditions. The gap can also be a source of potential or possibility, where new things can emerge or be realized. It can also be a source of tension or resolution, depending on the context and the specific characteristics or features of the gap. Overall, the gap can be seen as a space of potential and change, where different things can interact and influence one another, and where new possibilities can emerge.
