The Half Circle as Torus and Portal Symbol

The half circle, as half a torus, acting as a portal symbol, and a division between one reality and another, typically happening along the horizontal plane of that torus portal. The Tibettan example also has 4 portals at the diagonal corners. The Mesoamerican example has horizontal flows from the horizontal plane, some go up to a curly portal, some go down.

People following me for a while have seen this collection, but if you are new to my work, it's such an important symbol to recognize. https://ca.pinterest.com/stevenbhalls/half-portals/
