Mahadevan's sign number 66 is a composite character. The adjective calm or quiet is surrounded by four points of light. A speck of light denotes that something is true. It follows that a point of light at each of the cardinal points is an ideograph for the noun everywhere. Therefore, sign number 66 means that everywhere is quiet.
