Inverted Pentagram and Triangle Flow Markers
Inverted pentagram. Image A's pentagram versus image B's inverted one. I'm giving people a way to use the direction that a triangle is pointing, as a flow direction marker of energy (often through a portal, an inlet/outlet). Some people won't give up other meanings they were taught, but maybe later, and meanwhile there are many useful teaching points on the A and B pages, which I'm not covering on this post.
Image A's bird head is for the central flow path through a torus, it's upward but the curved beak means it also has a downward loop-back aspect. The center flow path is bidirectional. The bulge at the top of the wings, those are also portals, marked specifically as portals quite often with examples in this collection: https://ca.pinterest.com/stevenbhalls/wings-as-side-mounds/
Image A's bird feet are showing diagonal flow paths from the bottom-side portals to- and from- the core. Objects held by bird feet often show up and down flow direction markers https://ca.pinterest.com/stevenbhalls/bird-feet-holding/ and bird tails tend to be upward inward flow, but they can also be quite elaborate with outward flow markings. https://ca.pinterest.com/stevenbhalls/bird-tail/
Image B's bottom triangle is on the central flow path. These legs on B are not having extra markers about flow directions, but they at least hint of bidirectional flow. The side legs of B are equivalent to A's. The upper two portals go to horn blowers, straight horns are outflow, and these are pointing to the horizontal plane.
Image C and D are just examples of triangle shapes used for indicating 4 outflow directions of portals. Image E has 6 triangles on that famous star shape, it is found in worldwide use. https://ca.pinterest.com/stevenbhalls/star-of-david/ I chose to show image E because it has extra flow hints beside those 6 triangle portals. Image E also has a Hebrey "hey" (famous from Yod Hey Vov Hey), and hints about the flow implied by parts of it, which is cool.
