It would fill up with an energy that you have an unhealthy excess of and turn that energy excess into some energy that you lack. The idea is for a device that auto-balances energies in order to avoid issues like being too yin or too yang, or having anger issues or being a doormat.
I believe that balance is good and healthy both for mind and body and this would be an automatic balancing device. No idea if its a good idea. Some people might lose some of their quirks or not want to fix some of those imbalances.
