The solar plexus is referred to as Manipura by the Hindu tradition. It is the 3rd primary chakra. It is also referred to as the city of jewels. Not those jewels. Yogi stimulate this charka, and through meditation they attain the siddhi, or power to create, destroy, or save the world. Presumable not all three at same time which go against the scared practice of not being a big show off.
