  The second word, in the dative case “to” or “for” man, stands between the names of two very unlike objects, ‘character’ and ‘deity.’  Grammatically, it can attach to either indifferently, and seems intended to be heard with both, so that it counts twice. Because of its double role, the word forms a kind of syntactic glue between the otherwise diverse subjects, joining them together in a unity.  Traditionally having a good or a bad guardian spirit constitutes one’s “luck”–one is eudaimôn or dusdaimôn, fortunate or wretched, at the mercy of one’s divine overseer. But Heraclitus turns one’s luck into a function of one’s character, one’s ethical stance, by making “man” the link.
