 "Siddhachakra" most likely originally had only the "Panch Parmesthi", "Arihant" in the center and the other four in petals in four different directions.It may have been inspired from "Namaskara Valaya" based on the Namokar Mantra as in some older "Siddhachakra".The four last lines describing "phalashruti" (benefits) are depicted in addition to the petals at the four corners.
