Curly Fingers Symbolizing Downward Flow and Core Inflow

More curly fingers (for downward flow and inflow toward the core) with straight fingers (upward and/or outward flow).

My previous post on the subject is here.

https://www.facebook.com/share/p/1PcbrErV4n/ Image A is from Egypt.

Image B is from Persepolis.

Image C is reproduced many times on gravestones.

Image D has decorated sleeves that I cannot decode, but on C and D the arms are clearly showing horizontal plane flows and both polarities in the core.

Image E is modern but it nicely shows curly fingers and downward flow.

In my handshake collection, less than half of the images show straight and curly fingers together, so it's not a widely used symbol combination.

I imagine that mystery schools and secret societies teach a different meaning for various handshakes, but that shouldn't stop them from adding this to their understanding.
