Mahadevan's sign number 250 is a composite character. The noun method or way is surrounded by four points of light. A point 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 adverb everywhere. Therefore, sign number 250 means to be the custom or practice everywhere.
