From what can be gleaned with the limited information, Shinheuh live by feeding off of shinsoo, controlling Shinheu is a literal and direct form of domination, and it seems the main method, since they live by feeding on shinsoo to begin with, is to fill them with your own shinsoo such that they are solely sustained by your shinsoo. Since they are basically filled with your own shinsoo controlling them is simpler, assuming you have the ability to do so.

The Bowl/Tank is essentially a container filled with your own shinsoo (imagine a fish tank where the water is your shinsoo), such that by being contained within they are automatically bathed in your shinsoo, serving both to sustain them and simultaniously maintaining control without substantial effort. The bowl basically makes controlling Shinheuh a passive convenient action when not activly used, instead of requiring constant active control.
