There is no such thing as an inverted pentacle or pentagram.
That indicates an up or down. We draw the pentagram in a circle, we walk
around the circle. The pentagram means the same when we stand at the north
and when we stand at the south.
The myth of the inverted pentagram comes from those whose sources are books
and jewelry, not practicing ritual.
Drawn in the air, one point up and one point down have different meanings,
but neither is INVERTED, because inverted means there is a right top!
There is not!!!
