This sign, after the manner of South Carolina hexeri Lee Gandee, is often called "spiritual rain." For me, this manifests as inspiration, hence my name for the sign.
The central hex rosette invokes general good fortune. Tthe three pointed "star" is a powerful representation of spiritual forces (the number three is a sacred number in many spiritual traditions). The raindrops and rays of sun interspersed between the points represent the blessings falling from the spiritual realm and the thankful connection between the owner of this sign and the spiritual powers from whom the blessing flow.
