The vase represents an immersive world, or the technology that surrounds us that we have created. It also stands as the maternal symbol; in this regard it is positive because it is about nourishment. The vase is supposed to be in the "spill" position most of the time, so it implies water flowing, which is also a maternal symbol.
The vase may be held, but it may also be big enough so the user can go inside. The vase can hold things inside as well. It will have a texture that moves like water. It can spin. In general, it can do anything that means holding, or being immersed or related to water motion.
